Trim-Lok Edge Molding for 2014–2027 RAM ProMaster Passenger Side Rear Quarter Window Opening - 159" EXT

Finish your van window installation with a clean, professional appearance using this Trim-Lok Edge Molding for the 2014–2027 RAM ProMaster 159" Extended Wheelbase passenger side rear quarter window opening. This black textured push-on trim is supplied in a 12 ft length and is commonly used to cover the exposed sheet metal edge after cutting the van wall for a urethane-bonded window installation.

While edge molding is not required for the window to seal, it is a great finishing accessory for DIY camper van builders, professional upfitters, and van conversion shops that want to hide the cut edge from sight. The trim is designed to cap over both the internal and external edges of the cut wall opening, helping create a cleaner transition between the van wall and the installed window.

Designed for Van Window Installations

This Trim-Lok edge molding is ideal for covering the raw cut edge created when installing aftermarket van windows, fixed glass windows, sliding windows, awning windows, and other urethane-bonded camper van windows. It helps conceal rough cuts, exposed metal, minor uneven areas, and interior cut lines that may remain visible after cutting the window opening.

Installation Notes

The molding presses directly over the cut edge of the van wall. In some installations, adhesive foam or insulation material may be too close to the cut edge. If needed, carefully trimming that material back can help the edge molding seat more evenly and create a cleaner finished appearance.

Minor trimming may be required depending on the exact cutout, wall thickness, and installation method. Always test fit the trim before final installation.
