Trim-Lok EPDM Dense Rubber Window Locking Gasket – Fits 1/4” Glass and 1/8” Panel Edge, 25’ Length – Two-Piece Locking System (Inline), Weather Stripping Seal for Stationary Windows or Windshields Review:


I purchased the one-piece style gasket and the hooked installation tool to replace the side/rear window seals on a 1967 Mercedes Benz van because I had little experience putting two-piece gaskets (L406dg).The packaging for the 100-foot length arrived in two boxes.I had done enough research to know that any gasket material exposed to the outdoors will shrink over time, so my goal was to cut big sections and then make them fit.About 60' worth of window openings might be covered by the 100' roll, leaving plenty of room for errors, overages, etc.My go-to tool for 90 degree cuts was a hose cutter with an inch and a half-long blade. The 45s were created with a hose cutter, razor knife, and carpenters square.I have five out of nine windows installed, but I'm still unsure that I've mastered a "method" for locking the gasket. My left handedness while using a tool designed for righties is part of the problem.There have been instances where the right balance of moisture addition, attack angle, and flow of motion led to several inches of advancement that locked the gasket into place. The majority of the time, progress is gauged in half-inch steps.The item looks fantastic in its location! It is replacing a fifty-year-old two-piece gasket that has long since outlived its usefulness due to shrinkage, fading, and other issues.
