Trim-Lok ProMaster Rear Cargo Door Window Edge Molding, 8 ft | 1610SB3-343-PM-RCG-FT8

Trim-Lok Edge Molding for 2014–2027 RAM ProMaster Rear Cargo Door Window Openings

Finish your van window installation with a clean, professional appearance using this Trim-Lok Edge Molding for the 2014–2027 RAM ProMaster rear cargo door window openings. This black textured edge trim is supplied in a 12 ft length and is specifically designed to cover the exposed sheet metal edge created when cutting the rear cargo doors for a urethane-bonded window installation.

While edge molding is not required for a successful window installation, it is one of the most popular finishing accessories used by professional van upfitters, camper van builders, and DIY installers. The molding helps conceal exposed metal, rough cuts, paint imperfections, and uneven cut lines while creating a cleaner transition between the van wall and the installed window.

The flexible Trim-Lok design is engineered to cap over both the inner and outer wall skins of the ProMaster rear cargo doors, helping create a cleaner and more professional appearance around aftermarket van windows. It is commonly used on camper van conversions, cargo vans, work vans, fleet vehicles, RV builds, and commercial service vehicles.

Important: Edge molding is intended to be installed before the window is bonded into place. Because the trim covers the cut edge itself, installation becomes extremely difficult after a urethane-bonded window has been installed. For best results, install the molding immediately after completing the cutout and prior to applying urethane or setting the glass.

Installation Notes

Trim-Lok edge molding simply presses onto the cut edge of the sheet metal opening. Since the molding is designed to cover the cut edge itself, installation should be completed before the window is installed.

Because this molding fits over the cut metal edge, attempting to install it after a window has already been bonded in place is extremely difficult and generally not recommended.

In some applications, adhesive foam, insulation, or interior wall materials may extend too close to the cut edge. Trimming those materials back slightly can help the molding seat properly and provide a cleaner finished appearance.

Minor trimming may be required depending on cutout dimensions and installation methods. Always test fit prior to final installation.
