Video Transcript for LaSalle Bristol Roof Vent Installation Kit Review

Speaker 1: Today we're going to be taking a look at the Vent Installation Kit, part number 344270KITW. Now, in our kit, we're going to have two different types of screws in it. We're going to have a wood screw, which is just going to have a round head on it, and a flat head section for a screwdriver. Then we're going to have a sheet metal screw, which is going to have a 1/4" socket head on it, but also a flat head section. The machine screws, there is going to be quite a bit more than the wood screws, and by the time we get our vent installed, you may notice that you have a few extra machine screws leftover, and that's to mount the switch if your vent has a fan built-in.The kit is also going to come with plenty of butyl tape. As you can see, it's going to be several feet of it.

We're not going to need all this, but it is always nice to have it on hand in case we need to make any repairs, or possibly add another vent into another trailer, or anything like that. It's also going to come with a tube of self-leveling sealant, and this is to make sure that our vent seals nicely and there's no leaks in the exterior part of our vent. You will need a caulk gun, which you can pick up at your local hardware store, to apply it to the roof.We can go ahead an grab the vent now. We want to make sure that the bottom edge is going to seal nicely to the roof. Then we don't have to worry about any kind of leaks.

So we can take our butyl tape, and our butyl tape is going to make sure that it is a watertight seal, and the longer it's on there, the better adhesion it's going to have. So the longer our vent sits here, it is going to stick and hold on a lot better because it is going to take a little bit of time for this to set up. It is going to be rolled up, so just take our roll, unroll a little bit. We're going to start at one corner and just push down, going along the edge here. Once we get to the other side, we can go ahead and tear us a piece off.

We're just going to repeat that for all the four edges. Just go down, going along the edge till we get to the other side. We can leave the backing on until we get ready to put it in place, then we don't have to deal with it too much, worry about getting it on our hands, or anything like that.So I just want to peel off the backing and remove it, and make sure that the butyl tape is still stuck to the vent. It's all right if you have a little bit of overlap. Those will squish out once we put the vent down and it'll seal up nicely.

So we take our vent, line it up in the hole in the roof, make sure that it goes all the way in the hole on all four corners. I'm just going to go around, just pressing it slightly into place, then we can work on getting our hardware in.We're going to be taking a #8 sheet metal screw and going into each one of the holes going around the perimeter of the vent. Again, it's all right if that butyl tape starts to come out. That way, we know we're going to have a good seal. It will start to squish out around the edge as we start to screw it down.With all the hardware in place around the vent and securely attached, we want to make sure that there's no leaks, so we're going to come back with the self-leveling sealant and we're going to make sure to cover up the bolt holes, as well as that outside flange. So just go in a zigzag motion going across. As you can see with the sealant, after only a few minutes, it is going to start to disperse and start to level itself out, so it's going to fill in all these little gaps on its own without having to go around with a putty knife and smooth it out. Once it dries, it is going to be paintable, but still remain flexible, and it is going to adhere to most surfaces like aluminum, wood, and even concrete.That will finish up your look at the Vent Installation Kit, part number 344270KITW.

- 344270KITW

Exactly what I needed to install my ven t. 640155

- 344270KITW

Everything I needed was in the kit. Plus plenty of extra screws. The butyl tape is an awesome product. First time using it. The two tubes of sealer applied easily and leveled out nice. Professional looked job. The extra I had left over I resealed my solar panel and every seam on my roof. 634922

- 344270KITW

Received my Maxx Fan and roof vent kit on Monday 6/17/19 right on time and everything was their and in good condition. I installed the Maxx Fan on my 2017 GMC cargo van the same day, took me a little longer than I thought it would but not bad for a 74 year old guy. I watched the videos that etrailer had on their site and some other [videos] and that really helped for a first time doing this type of install. I had the wiring ready to go and the fan worked great, thanks etrailer for the fast service and a great price on the Maxx Fan. 659547

- 344270KITW

The sealant is difficult to apply smooth and straight but that should be expected with this type of joint design. The e-trailer videos helped with the process. The trick is to carefully apply the sealant where it is needed and do minimal tooling to smooth and fill gaps. No product data sheet is apparently available to understand how to work with the sealant or to provide preparation recommendations, cure times, and safety considerations. No success with locating the product data on the internet or the manufacturer's site. The butyl tape should be shipped flat or attached to a flat sheet of cardboard. When I opened the box it was molded into to a taco shape and had to be set out overnight to creep back into a flat roll. I did not use the carbon steel self tapping screws. 670287

- 344270KITW

The kit does what it is supposed to do. I only used one tube of the sealant and the machine screws were useless. Recommend having self tappers on hand. 691662

- 344270KITW

All came in two separate boxes but at the same time. Packed well and no damage. 688160

- 344270KITW

Works great no problems installing. 683036

- 344270KITW

Not great but not bad and seemed to be a good value. Purchased to replace a roof fan/vent. I liked the convenience of buying the butyl tape and lap sealant together. The screws were okay but not what I would use on a RV roof but the fan came with some nice stainless steel screws anyway. 680541

- 344270KITW

Everything showed up early, very good s ervice!!! 679511

- 344270KITW

products arrived quickly and every thing I purchased had a great price. 664847

- 344270KITW

great value, the self leveling caulk looks nice and there is enough tape to wrap the whole trailer 652399

Great products. Good price and easy to work with. 639127

Great kit, used for installing new roof vent and repairing existing ones. 592359

Do you have a question about this Accessories and Part?

  • Replacement Roof Vent Cover for 2000 Skamper Sport 23D Pop-Up Camper Trailer
  • Thank you for the photo of your trailer roof vent for which you need a new lid. I conferred with several of my associates regarding the photo of your trailer roof vent which requires a replacement lid. Interestingly, this hinge design seems about halfway between a 3-point type like # 69284 and a continuous type like # BV0554-01. After much back and forth we came to the determination that you need a 3-point. We have only two options for a 3-point-hinge type lid, parts # 69284 and...

  • What Does Clamp-On Mean For Fan-Tastic Vent Roof Vent # FV801208
  • Instead of the normal installation of a roof vent that requires a kit like part # 344270KITW, the Clamp-on feature of the # FV801208 fan uses four screws to attach the garnish on the bottom to the dome assembly on the top to clamp the fan to your roof. You will also need a sealant like part # 0160297 to give you a waterproof seal.

  • Replacement Parts for Fan-Tastic Fan Malfunction on 2003 Cedar Creek 5th Wheel
  • It sounds like you need the Fan-Tastic Vent 3350 Series Upgrade Kit - Off White # FV803358 which will replace all the "guts" of your fan. It sounds like there is a circuit board issue and there aren't replacement parts for everything malfunctioning outside of this kit. If you also want the fan, you can use the # FVK8017-00. Alternatively, if you want to replace the entire assembly, I recommend the Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat - Powered Lift - 14-1/4" x 14-1/4"...

  • Supplies Needed to Install Replacement Ceiling Vent
  • The MaxxFan Deluxe Roof Vent w/ 12V Fan and Thermostat # MA00-06200K will install in the exact same cutout as the stock vent. You will simply need some sealant and screws. Many will choose to use the Roof Vent Installation Kit - Sealant, Butyl Tape, Screws - White # 344270KITW. You don't absolutely need both butyl tape and sealant, so many will use the LaSalle Bristol XTRM Universal Self-Leveling Sealant - White - Qty 1 # 34427034145-1 or # 0160297 and then the Zinc Sheet Metal Screw...

  • How To Add Power Wire for MaxxFan Deluxe Vent with Fan
  • The MaxxFan Deluxe Roof Vent w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed - Smoke # MA00-07500K requires 12V power at 5 amp draw. Since you are installing in a location that doesn't have power wires run, you will need to run a power wire like # 12-1-1 or # 10-1-1 (sold by the foot) to your battery or to another 12V power source that can handle that draw. There is a good chance the bathroom fan or a light could be a good tie in point as long as you tie in prior to a switch. You...

  • Is Butyl Tape Needed When Installing MaxFan Roof Vent
  • When installing the MaxxFan Roof Vent # MA00A04301K that you referenced you will want to use butyl tape on the vent edges in addition to the sealant that you will apply around the unit to cover up bolt holes and any other areas that might lead to a leak. I have attached a sample vent installation on a different model vent just so you can get a better idea of the process. We do have the Roof Vent Installation Kit # 344270KITW available that includes a 10.1 oz bottle of sealant, a 60...

  • Roof Vent Recommendation to Fit 14-1/2 inch Square Opening
  • A 14-1/4-inch x 14-1/4-inch rough trailer roof opening is very common and we offer a whole range of complete vent assemblies and also replacement lids and other parts for this size vent. Vents that fit this opening size are 14 x 14 size and the linked page will let you see all that we offer. These include both manual and powered types, plastic-domed vents in various colors and also metal vents. For instance, if you prefer a smoke-color manual vent you could use Ventline # V2092SP-29....

  • Recommended Roof Vent for Cargo Trailer Toy Hauler
  • For your roof vent, I recommend the Ventline Ventadome Trailer Roof Vent # V2092SP-29 which will let the light through and will mount to the roof only. The garnish/trim on the inside is designed for roofs between 1-7/8 and 3 inches thick. I recommend installation kit # 344270KITW for best fit and seal. If you determine you would like to add a fan, then I recommend the Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible # FV801250 which will fit ceilings up to 4 inches thick. The garnish/trim...

  • Installation and Wiring of Trailer Roof Vent with 12V Reversible Fan
  • The Fan-Tastic Vent Roof Vent w/ 12V Fan - Reversible # FV801250 will fit in the same opening as your current vent as they are industry standard size. I recommend using the Installation Kit # 344270KITW to install and seal your vent. You can run wires directly to your trailer battery or into the same circuit breaker as your lights using # 16-1-1. That will allow you to use your fan and have the lights off versus just splicing into the light power. The motor will draw 36 watts and...

  • How to Select the Correct Replacement Roof Vent and Roof Vent Lid or Cover 2012 Dutchmen Aerolite
  • Trailers can come equipped with a variety of vents depending on the options that were selected when it was initially purchased. Dutchmen will normally provide literature on the specific appliance and fan models with the purchase of the trailer. If you no longer have this documentation, we should still be able to help you find a replacement. To replace the entire vent, you will need to measure the existing vent so that you can make sure the replacement will fit in the existing opening....

  • Replacement Lid for 14 x 14-Inch Trailer Roof Vent
  • Thank you for the photo of your R-Vision Trail Lite camper's roof vent. You can use Ventline Old Style Rounded Dome # BV0554-01. If you prefer to replace the entire vent with a new one you can use a kit like Ventline # V2092SP-28 along with install kit # 344270KITW.

  • Recommended Roof Vent for 2013 Ford Transit Connect
  • I have a couple of different options for a roof vent on your 2013 Ford Transit. A lot of our roof vents sit around the same height, so it really just depends on what kind of style you would like to have. The Ventline Ventadome # V2110SP-24 is a good option because it only adds 2 inches in height when closed, and 11 inches in height when opened. You can also make sure that your roof vent matches the rest of your Transit by painting it. This manual vent doesn't include a fan and requires...

  • Can Maxxair Deluxe Roof Vent MA00-06200K Mount Off Center on Van Roof
  • MaxxFan Deluxe 12V Roof Vent # MA00-06200K and similar RV roof vents can be installed off-center in the roof of your Transit T-150. The minor difference in depth from the roof corrugations is not an issue since you'll be using an install kit with flexible sealant like # 344270KITW. For wiring the vent to your 12V power I recommend using 10-gauge wire # 10-2-1 and butt connectors # 224775.

  • Replacement Roof Vent for 1992 Palomino Filly Pop-Up Camper
  • We have many types of trailer roof vents and vent parts but we do not have a way to look up the vent originally installed in your 1992 Palomino Filly so I suggest confirming the dimensions. Most often square roof vents are 14 x 14-inches and fit roof openings that are generally 14-1/4 x 14-1/4. Based on photos of your pop-up that I could find it appears you do have a 14 x 14 vent so I linked for you our entire range of trailer vents in this size. We have manual vents, 12V powered vents...

  • Fan-Tastic Vent part # FV807357 is a partial unassembled upgrade kit but we do have complete fully-assembled powered vents like this that will fit the same standard 14-1/4 x 14-1/4 RV roof vent opening. This kit is compatible with many but not all Fan-Tastic Vent models so it will be helpful to tell me the model number of your vent which you'll find on the motor. Please refer to the linked page to see all complete 12V powered vents like the Fan-Tastic Vent # FV807350. This USA-made unit...

  • A motorized trailer vent such as the Fan-Tastic Vent model # FV802250 has a replacement fan blade/motor assembly # FVK8017-00 available but this has a manually-operated lid with a hand knob to open and close it. Since yours is not working it is probably going to be easier and less of a project to replace the entire assembly. Roof vents like this are all standardized in size so it will be easy enough to choose a new one and mount it in the existing trailer roof opening which is typically...

  • Replacement Parts Needed for a Northern Breeze Model V2525 Vent

Item 7 - # VC0476-00 Item 14 - # BV0115-04 We don't have items 1, 15 and, 16, but it sounds like 15 and 16 come with the item 14. In all honesty it would be much more cost-effective for you to just purchase a whole new 14" x 14" unit # V2094SP-34 as opposed to piecing it out. You would just need the screws and sealer...

  • Replacement Roof Vents and Vent Lids for 2008 Jayco Octane Toy Hauler
  • Sorry about Mother Nature giving your trailer a beating. We have both complete standard 14 x 14-inch roof vents as well as just replacement lids in many colors and in the most popular hinge designs. If you care to just replace the lids only (and not have to tear out all three whole vent assemblies) you can refer to the linked photo that shows the four common hinge types for 14 x 14 roof vents. Just match your hinge type and then select that one on the page for replacement lids that...

  • Thickness of Roof for the Ventline Vanair Trailer Roof Vent Part # VP-543SP
  • The Ventline Vanair Trailer Roof Vent part # VP-543SP will fit a roof from 1-1/2" - 2-1/2" thick out of the box. Since you have a 3-1/4" thick roof then you will need to use the Replacement Garnish Extension Ring for Ventline Vanair Trailer Roof Vent part # BVA0228-01-46 which allows for a roof from 2-1/2" - 3-1/2" thick. I also recommend using the part # 344270KITW which comes with everything you need for installation.

  • Trailer Roof Vent Recommendation for 110V Shore Power
  • The MaxxFan Deluxe Roof Vent # MA00-06200K is designed for use with 12V power. If you wanted to power it using shore power then the best way to do that would be with a converter like the Progressive Dynamics PD9100 Series Inteli-Power Converter # PD9140A which is meant to connect to 12V lighting and appliance circuits. Currently (as of February 2019) the only trailer roof vent available that is compatible with 110V shore power without a converter is the Ventline Roof Vent # V2128SP-01....

  • Trailer Roof Vent with Low-Profile Height for Clearance at Garage Door
  • The 14 x 14-inch trailer roof vent with the lowest profile is the manual Ventline Ventadome model # V2110SP-24 which has a flat metal lid that will be approximately 2-inches above the trailer roof once installed. This does not have a 12-volt fan like the Fantastic Vent EZ Breeze # FV800601 that you referenced which will extend above the roof by approximately 3-1/2-inches. For a vent with a 4-speed 12V fan and manual lid lift we offer MaxxFan Roof Vent # MA00A04301K which when closed will...

The Ventline Ventadome Trailer Roof Vent # V2094SP-28 has a manual lift and a 12V fan. The Ventline Ventadome Roof Vent # V2119-601-00 has a powered lift and a 12V Fan.

  • Install/Sealant Kit to Use When Installing Fan-Tastic Roof Vent # FV800900
  • You will need to use a sealant when you install the Fan-Tastic roof vent part # FV800900 that you referenced. For that we have the Roof Vent Install Kit part # 344270KITW which comes with all of the sealants you would need plus screws to attach the vent. I attached an install video that uses this kit on a similar roof vent for you to check out as well.

  • Trailer Roof Vent Installation Kits and Sealers
  • The Ventline trailer roof vent # V2092SP-28 does not include mounting screws or sealant. The reason is that trailer roofs vary in their materials and thickness and if hardware were to be included it would not work for each and every application. But we do have vent install kits and sealants to help you get the job done. I linked a video to help too. We have vent installation kit # 344270KITW for trailers with a metal roof; this includes both hardware and sealant. We also have a kit for...

  • Replacing Fan-Tastic Fan with MaxxAir Deluxe and Relocating Fan-Tastic Fan on 2018 Lance 1475
  • Yes. A mobile tech can replace the Fantastic Fan easily with a MaxxFan Deluxe like # MA00-07500K. The non-walkable roof is the biggest issue, but dispersing weight over the camper roof and supporting as much weight as possible on a ladder or other support will allow accessibility on the composite roof. Swapping out the bathroom vent for the Fantastic Fan will be a similar swap and the rain cover can easily be moved as well. It actually will be an easier swap because of the clamping...

  • Roof Vent Needed with 12V Fan That Sits Under 5 Tall
  • The Ventline Ventadome Trailer Roof Vent # V2094SP-34 that you referenced actually sits only 4-1/2" above the roof when it is closed so it will fit in your garage! It comes with a 12V fan that is powered by DC. Most of our vents fit this description though so you are in luck! If you are looking for a vent that can stay open and still fall under your 5" height restriction then you will need the Ventline Vanair Trailer Roof Vent # VP-543SP. This is a round vent with a diameter of 6-1/4"...
