Video Transcript for Review of TRC Enclosed Trailer Parts - Butyl Tape - 362BT-18X1-50

Today we'll be taking a look the butyl tape for enclosed trailers. Now this is going to be an essential part of your install for any kind of vent or fan that you might put on your enclosed trailer. This butyl tape will create a nice watertight seal for that fan or vent. It can adhere to not only roof membranes on your trailer but also to glass, aluminum and galvanized steel. So it's kind of this putty-like really sticky material. It comes pre-formed and it's a synthetic polymer base.

So you pretty much just unroll it as you need. Stick it where you need it to go. Whenever you unroll it, you can just tear it off into however big a size, chunk, you need. This roll here is going to be 50 feet long. It's an eighth-inch thick and an inch wide.

So I'll show you that on the ruler here. Roughly an inch wide as far as the butyl tape itself. Of course, it has that little brown backing so it doesn't completely stick to itself. And, again, we're going to get 50 feet total with this. So it should be enough to get most of those enclosed trailer accessories, like a vent or a fan installed and still have some extra left over.It does remain flexible even after being on the roof for a long time, going through hot and cold and, again, it's going to create that nice watertight seal.

If you need any other accessories for your fan or vent install, like self-leveling adhesive, which is typically going to go over the top of that shroud off of that vent or fan, we also have that available here at etrailer.com if you want to pick that up. Hardware, the vents and fans themselves, we've got all those accessories for you and more right here at etrailer.com. And that's going to do it for our look at the butyl tape for enclosed trailers.

Used the Butyl tape to seal off the solar slide out topper in stalled on a 2021 Winnebago micro Minnie. 2108 DS The tape works well as a sticky place holder while installing the top slide rail and under brackets

Ordering was simple, and shipping was quick. The project is still in process so I can't comment of the product.

- 362BT-18x1-50

Due tyo flopping around loosely inside the large shipping box, the roll was pretty beat-up and misshapen around the outer edges.However, it unrolled OK as long as I was careful to not "get ahead" of myself with the brown paper and the butyl tape, and working to not let the tape stretch longer than its original length. Applying it to a powder-coated aluminum flat bar, it wanted to stick to my fingers more than the bar, so that part was a bit tricky. Once pressed in place, on the fiberglass side of my trailer, it made what appears to be a water-tight bond, all's well.

Appears to be ok. I haven't used it yet.

  • Slide Topper For A 2018 Avenger 28dbs With A 14' Slide
    For your 2018 Avenger 28dbs I recommend the Solera RV Slide-Out Awning - 14'7" Wide - 48" Projection - Black Item # LCV000251477. This topper provides you with 3" of over hang on each end. You want the edges of the canopy to at least meet the outer edge of your T-molding that runs vertical on your slide out. This ensures you have a 3" overhang on each end past the edge of the inner box to prevent anything from blowing onto the top of your box from an angle. I also recommend putting Butyl...

  • Solera RV Slide-Out Awning Bracket Dimensions and Attachment Instructions
    I have linked the photo I believe you are speaking of. The bracket on the Solera RV Slide-Out Awning part # LCV000182037 is right at 2" which should allow you to mount it in the space you have. We have always used the supplied fasteners which are threaded screws and have had zero issues. Using butyl tape like part # 362BT-18x1-50 also helps out in sealing the holes you create but acts as a slight buffer and helps keep any wiggling or movement to a minimum.

  • How to Properly Seal When Installing a Roof Vent
    When installing the MaxxFan Deluxe Roof Vent w/ 12V Fan, Thermostat, and Remote # MA00-07500K you will want to use both the Butyl Tape # 362BT-18x1-50 for under the flange and Alpha Systems 1021 Self-Leveling Sealant # AL98KV to cover the flange and screws to get a complete seal. I have included an installation video that demonstrates installing the fan and the use of the butyl tape and self leveling sealant.

    For a slide out that is 103" wide you need the Solera RV Slide-Out Awning - 9'1" Wide - 48" Projection - Black Item # LCV000168325.

  • Slide Toper For 2020 Sierra 321RL
    Ideally when you put a slide topper on, you would have a couple inches of overhang on the right and left sides. However, in your case, there just is not room for that. To have a slide topper you will have to buy one that is a little smaller than your slide. This means that instead of having a topper that is a couple inches bigger on each side - you will have a topper that is a couple inches too small on both sides. Most RV'ers will say that a slightly smaller topper is far better than...

  • Slide Topper For A 2018 Lance 2375 TT With A 90 Slide Box

Since there are so many different variations of campers and RV's, the awning extrusion rails are included in every kit. Not all campers and RV's will use them. Some are equipped with what you have, which doubles as a gutter with extrusion, some have the extrusion separate from the gutter and pre-installed, and some have just a...

  • Mounting of Solera RV Slide-Out Awning
    For the Solera RV Slide-Out Awning, # LCV000165063 and all other awnings in this category, if at all possible, you will want to mount with a three inch height above top of slide out flange so as to provide the needed slope for proper draining when extended. Please note the linked installation video where Shane walks through the steps of measuring and installation. I highly suggest that you use Butyl Tape, # 362BT-18x1-50 when making the installation.
