Purchase options and add-ons

  • Super Cap Seal XL dimensions are 2 1/8" Width x 1/2" Height x 23' Length. For beds less than 8ft use Super Cap Seal XL 20ft (ASIN: B00NCCNUJQ).
  • 2 1/8" wide triple bulb seal gives you greater coverage area for filling all bed rail gaps. Use on caps that weigh more than 200 lbs. Easily trims to size to fit smaller width front bed rails. Complete kit includes seal, butyl tape, alcohol pads and detailed instructions for a professional installation.
  • Excellent compression set resistance for maximum service life and vibration absorption. Long-lasting EPDM rubber is preferred by professional installers over PVC/foam seals.
  • No need to replace this seal every time your cap is removed. MADE IN U.S.A.
  • Professional Installer Review: "We don't use the Super Cap Seal XL very often, but when we do it works great." Eric (General Manager, A & A Topper Sales & Service Center) Lakewood, CO

Customers say

Customers like the quality, ease of installation, and performance of the weather stripping. For example, they mention it's a heavy duty seal that really seals your cap and provides a good support for the cap. That said, some complain about the adhesion, saying that the tape-like adhesive doesn't stick well to fiberglass. Opinions are mixed on fit.

Great product...but
2 Stars
Great product...but
Well, its a great product , but....Going by the measurments it "should have" been long enough for my 8' aluminum truck cap . It was about 8" to "short" . I didn't waste any , made the proper notches , but it came up short . I wish I would have measured it "Before" I unrolled and started cutting , as My first thought was it doesn't look long enough.Having to do this in cold weather I hurried to get it done and didn't take the time to "Measure" the length of the roll before starting. (My Bad!) I ended up rolling some workout mat to the same thickness and filling in the last 7-8" under the cap .Excellent product that is pretty easy to install and cut as directions , but it was about 8" short of doing the job for a standard 8' truck cap on a early 90's Frod F150....Its 22'8" Outside measurements on this cap so it (the roll length) WAS SHORT by atleast 7-8" ! It is advertised to be 23' ....it was NOT .
