What Is a Windshield Lockstrip?

The windshield lockstrip is the insert that fits into the groove of compatible gasket-style windshield weatherstrip.

Once the windshield glass and weatherstrip are properly positioned, the lockstrip is inserted into the gasket to help secure the glass and weatherstrip assembly.

You may also see this part referred to as a windshield lock bead, windshield locking strip, glass seal lockstrip, windshield gasket insert, or windshield weatherstrip lockstrip.

Over time, the original lockstrip can become faded, hardened, brittle, cracked, damaged, or missing. Replacing it is an important finishing step when installing new windshield glass or weatherstrip.

Black OEM-Style Appearance

This replacement lockstrip has a black finish for a clean, factory-style appearance around the windshield.

It is manufactured from original specifications using high-quality ozone-resistant material for an authentic replacement.

A center cover clip is included to finish the point where the ends of the lockstrip meet.

Installation

This lockstrip is designed to be installed during windshield glass replacement into compatible windshield weatherstrip designed to accept a locking strip.

Because proper glass and weatherstrip installation is important for both fit and sealing, Precision Replacement Parts recommends contacting a professional automotive glass technician for installation.

The windshield weatherstrip and glass are not included with this lockstrip unless otherwise specified.
