The Precision Glass Run Channel, Left or Right Hand GRB 3110 72 is a 72-inch replacement glass run designed to guide and seal side windows in left- or right-hand vehicle doors. It restores proper window alignment, reduces wind noise and water intrusion, and protects the glass and regulator from wear. Made from durable rubber with a reinforced backing, it delivers long-lasting flexibility and reliable performance for restoration, collision repair, or routine maintenance.
Features:
- 72-inch glass run channel for left or right hand door applications; universal length for many full-length door openings
- Constructed from durable, flexible rubber compound with reinforced backing for long service life
- Guides and seals the window to reduce wind noise, water intrusion, and vibration
- Press-fit design for a secure, OEM-like fit; resists shrinking and cracking over time
- Ideal for vehicle restoration, collision repair, and routine door/window maintenance
- Can be trimmed or adjusted to fit specific door rails when needed
Installation / Application:
- Difficulty: 3/5
- Estimated time: 1–2 hours
Instructions:
- Lower the window several inches to expose the glass and make removal easier.
- Remove the door panel and any inner vapor barrier per vehicle-specific procedure to access the glass run groove.
- Carefully detach any clips or retainers holding the old glass run; remove the old channel by sliding or pulling it out along the door frame.
- Clean the channel groove and surrounding area of dirt, adhesive residue, and old rubber using solvent and a rag. Allow to dry.
- If needed, trim the new channel to approximate length, leaving extra to seat fully in the door frame; test-fit before final installation.
- Apply a thin film of silicone lubricant to the glass run interior to ease window movement and help seat the channel.
- Starting at one end, press the new 72" channel into the groove, working along the length to ensure the channel seats evenly. Use gentle heat if the rubber is stiff (avoid overheating).
- Reposition the window into the channel and cycle it up and down slowly several times to seat the glass and confirm smooth operation and proper alignment.
- Reinstall any retainers, the vapor barrier, and the door panel. Verify there are no gaps and check for wind noise and water tightness after installation.
