Gordon Glass 11-5381 Accordion Boot Seal | Spring Clips are Facing The Same Direction | Slider to Slider Accordion Boot Seal | 20 FT | Compressed Width of 2" and 4-1/2" When Fully Stretched

I installed a sleeper cab with pass thru on my truck 8 years ago using this boot seal and it lasted longer than the cab. I just recently removed the cab so I could repaint it and relace the door & window seals. There were no issues with the accordian seal. My truck lives outside everyday like an RV. I rarely take time to clean and condition this seal so it is resilient.When I removed my old seal, I damaged it because I used 3M weather stripping adhesive when I installed it. Also, there was some corrosion on the metal skeleton at the ends where sealant finally broke down and allowed moisture to contact the metal skeleton.The instructions inform you that NO SEALANT is needed when installing. This makes installing much cleaner and easier. And you can remove it without damaging it if you need to.The seal did have quite a lot of powder on it so be sure to use air to blow out the channel so it will be watertight.Definitely worth the cost even in today's inflated economy.

The quality seems very good. I installed this on a 1986 peterbilt 359 and installation was straightforward and easy and it sealed up nicely. I used weatherstrip adhesive on the corners and the joint

Perfect for my truck

Waterproof and looks good
