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.

Roof Vent Installation Kit - Sealant, Butyl Tape, Screws - Beige - 344270KITB

Average Customer Rating:  4.7 out of 5 stars   (6 Customer Reviews)

When I received the shipment, I found the tape was messed up due to how it was packaged in the box. You get quite a bit of the product so I was able to work around the damaged stuff to get enough for the installation. The screws shipped with the kit are too short and small. I didn't use any of them and instead put them in my RV kit with other screws for on-the-road repairs. If I ever do another fan install, I'll buy the sealant and tape and use appropriate size screws. 649912

Max fan RV vent arrived with mounting kit a few days ahead of expected delivery date. Excellent service and best pricing I could find on this item and free shipping ...WoW! 614329

We purchased this product for two of our projects, upgrading our HD TV antenna and installing a vent fan in my truck cap. Both products worked well. Both the truck cap an antenna install have no leaks, rain tested at 60 MPH. The only problem was with the way the Butyl Tape packaged. The roll was not secured on type of cardboard pallet, it was bent over to fit in the box so when we received it it looked a bit like a potato chip. After a day lying on a flat surface and some hand shaping all ended well. 670034

  • Replacement 14 x 14 Trailer Roof Vents and Installation Kit
    Standard square RV roof vents usually measure 14 x 14-inches and typically the roof opening measures very slightly larger than this, about 14-1/4 x 14-1/4. The Ventline vent # V2092SP-28 that you referenced is this 14 x 14-inch size. If your existing roof openings measure 14 x 14 then this vent or any of the similar units we offer will fit well. This particular vent includes a garnish (the interior plastic trim piece that covers the gap between the vent and the roof) which will work...

  • Rough Opening Size for MaxxFan Deluxe Roof Vent Item # MA00-06401K
    The 14-1/4 by 14-1/4 is the standard opening for a roof vent or vent fan, so the MaxxFan # MA00-06401K would be a great choice to replace your existing fan.
