Seat Rail Cover / Seat Track Sealing Trim

Compatible with Mercedes Vito / Viano / V-Class (W639 / W447)
Reference Part Number: A6396840918 7C45

One of the most common problems with sliding seat systems is dirt, sand, small stones, and debris entering the seat rails. Over time, this contamination causes resistance, noise, uneven movement, and in many cases makes seat adjustment difficult or unreliable.

This seat rail cover is the most effective solution to that problem. It seals and covers the exposed seat tracks, preventing debris from entering the rails and ensuring smooth, trouble-free seat movement.

Key Benefits

• Prevents dirt, sand, and small objects from entering seat rails
