✅ In Stock The PRP 2175TL is a 21mm conventional-style underglass molding with an integrated decorative trim line. It creates a clean, finished appearance along the glass edge and is designed for use in a wide range of standard glass openings. Tape-backed for fast, secure installation. Specifications Part Number: PRP 2175TL Width: 21mm Length: 75ft (22.8m) roll Style: Conventional with Trim Line Tape Backing: Yes Application Designed for conventional glass openings where a finished, decorative trim line is preferred. Use this molding wherever a clean edge profile with an integrated accent is required. Check the width guide below to confirm fit before ordering. Width Selection Guide Measure the gap between the glass edge and the pinchweld or channel. For conventional-style molding, the width should fill the gap without overhanging onto the glass surface. At 21mm, this is one of the wider options in the Precision line — suited for wider openings commonly found on truck cab glass, rear windows, and some commercial applications. What's the difference between conventional and underside molding? Underside molding (USM) runs underneath the glass edge and is hidden from view. Conventional molding with a trim line sits along the edge of the glass and is visible from the exterior, creating a finished decorative appearance. PRP 2175TL is designed for applications where that visible edge detail is part of the finished look. What does the trim line do? The trim line is a decorative accent integrated into the molding profile — it runs the length of the strip and gives the installation a clean, factory-finished look from the outside. It's common in applications where bare molding would look unfinished or where aesthetics are a priority alongside weatherseal function. Is this molding tape-backed? Yes. PRP 2175TL includes a tape backing along the bonding surface, which helps secure the molding in position during installation. Clean and dry the surface before applying for best adhesion. How much molding do I need per job? For a standard windshield, most installers use 6 to 9 feet of molding depending on the vehicle. A 75ft roll covers approximately 8 to 12 installations. If you're doing high-volume work, buying by the roll is significantly more cost-effective than per-piece purchasing. How do I cut and shape this molding? Use a sharp utility knife or molding cutter for clean cuts. For corners and curves, warm the molding slightly — a heat gun on low or warm water — to make it more pliable before bending. Avoid sharp kinks; gradual curves hold their shape better and seal more evenly.
