Trim-Lok Sprinter Driver Side Rear Quarter 144 Window Edge Molding, 16 ft | 1610SB3-343-SPR-DR3-144-FT16

Trim-Lok Edge Molding for 2007–2027 Mercedes-Benz Sprinter Driver Side Rear Quarter Window Opening - 144" Wheelbase

Finish your van window installation with a clean, professional appearance using this Trim-Lok Edge Molding for the 2007–2027 Mercedes-Benz Sprinter 144" Wheelbase driver side rear quarter window opening. This black textured edge trim is supplied in a 16 ft length and is specifically designed to cover the exposed sheet metal edge created when cutting the rear quarter panel for a urethane-bonded window installation. This kit includes extra material to allow trimming and fitting during 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 Sprinter body structure, helping create a cleaner and more professional appearance around aftermarket van windows. It is commonly used on camper van conversions, expedition vans, cargo vans, work vans, fleet vehicles, and RV builds. 

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. Internal steel clips help retain the molding while allowing flexibility around curved sections of the opening.

Because this molding installs directly onto the exposed cut edge, it should be installed before the window is bonded into place. Installing edge trim after a window has already been installed is extremely difficult and generally not recommended.

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