Description
Trim-Lok Bulk Edge Molding (1610SB3-343) – Fits 1/8" to 1/4" Wall Thickness – Sold Per Foot
Trim-Lok® 1610SB3-343 Edge Molding is a professional-grade, flexible PVC edge trim designed to cover exposed edges of sheet metal, fiberglass, aluminum, plastic, and composite panels while creating a clean, finished appearance. Sold by the foot, this universal edge molding is commonly used for camper van window installations, RV conversions, cargo trailers, marine applications, automotive fabrication, and industrial equipment. The steel-reinforced internal clips and gripping tongues provide a secure mechanical grip without requiring adhesives in most applications.
The larger profile of the 1610SB3-343 makes it ideal for thicker wall materials ranging from 1/8" to 1/4". Its black pebble texture closely matches many OEM interior and exterior trim finishes while helping conceal rough cuts, exposed metal edges, paint imperfections, and fabrication marks. This profile is especially popular for van window installations on the Mercedes-Benz Sprinter, Ford Transit, and RAM ProMaster rear doors. :contentReference[oaicite:1]{index=1}
Because this is a universal bulk product, year, make, and model do not apply. It can be cut to length and used wherever a durable edge-protection solution is required.

Installation Notes
Trim-Lok edge molding is designed to press directly onto exposed edges without requiring adhesives in most applications. Internal steel clips and gripping tongues help maintain a secure fit while allowing the trim to conform around curves and irregular openings.
For van window installations, edge molding should be installed immediately after the cutout is completed and before the window is bonded into place. Because the molding covers the exposed cut edge itself, installation after a urethane-bonded window has been installed can be extremely difficult.
Why Choose Trim-Lok?
Trim-Lok products are widely used throughout the automotive, RV, marine, transportation, and manufacturing industries because they provide a durable, professional solution for protecting and finishing exposed edges. The steel-reinforced construction offers superior retention while maintaining flexibility for curved openings and complex installations.
