Seat Belt Presenter Cover for Mercedes W124 / C124

This is a precision-engineered replacement for the seat belt presenter cover on the Mercedes-Benz W124 and C124. The factory presenter cover — OEM parts A1246921122 and A1246921222 — is the plastic housing that wraps the belt delivery arm on the B-pillar, and it is one of the most failure-prone trim pieces on the W124. It cracks at the snap-fit points, becomes brittle from UV exposure, and is completely unavailable new through Mercedes-Benz. We re-engineered this cover as a direct drop-in replacement in ASA composite.

✅ AVAILABLE IN BLACK & CREAM BEIGE: Two colour options to match the most common W124 / C124 interior specifications. Fits W124 sedans and C124 Coupé and Cabriolet variants.

The Engineering Edge

• ASA High-Performance Composite: Moulded from engineering-grade ASA — UV-stable, heat-resistant, and structurally superior to the factory material. The snap-fit geometry is redesigned with increased engagement depth, meaning the cover locks onto the belt arm mechanism and stays put permanently.
• Snap-Fit Redesign: The factory snap-fit tabs are the primary failure point. Our version features wider tabs with a deeper locking profile — the cover installs with a clean snap and will not work loose from vibration or temperature cycling.
• Direct OEM Replacement: Replaces A1246921122 (Left/Driver) and A1246921222 (Right/Passenger) directly. Installs to the factory belt arm with no tools and no modification to the surrounding B-pillar trim.
