Precision Glass Weatherstrip Lockstrip WLS 900 is a durable lockstrip designed to secure glass weatherstrips into door and vent channels. It holds the rubber weatherseal firmly against the glass, preventing water intrusion, reducing wind noise and vibration, and restoring proper window alignment and operation. Built for durability and ease of replacement, the WLS 900 is ideal for repair and restoration projects where a reliable, corrosion-resistant lockstrip is required.
Features:
- Corrosion-resistant steel core with protective plating for long service life
- Secures rubber weatherstrip to glass, preventing leaks and reducing wind noise
- Restoration-grade replacement for worn or damaged lockstrips on doors and vents
- Easy to trim and fit for a precise, secure installation
- Helps maintain proper window alignment and smooth operation
Installation / Application:
- Difficulty: 2/5
- Estimated time: 30-60 minutes
Instructions:
- Remove the door or vent panel as needed to access the window channel and lower/raise the glass to a position where the lockstrip can be removed and installed safely.
- Carefully lower the glass into the channel and support it so it won’t shift during work. If needed, remove the glass from the door following vehicle-specific procedures.
- Cut and peel out the old lockstrip: score any adhesive and pry the old strip free with a trim tool and pliers. Remove all old adhesive, rust flakes, and debris from the glass channel.
- Clean the channel thoroughly with solvent and dry. Inspect the channel for damage and treat any rust or rough spots before installation.
- Measure the new WLS 900 against the channel and trim to the correct length with hacksaw or metal snips. File any sharp edges.
- Position the new lockstrip onto the glass or into the channel according to application: slide the strip into the glass channel or press it into the rubber weatherstrip until fully seated. Use a rubber mallet gently if needed to work it into place.
- If the application calls for adhesive or clips, apply as recommended for your vehicle to secure the strip. Reinstall the glass into the door and verify smooth operation.
- Reassemble the door or vent panel and test the window for correct alignment, smooth travel, and a watertight seal.
