Front door triangle sealing strip L/R

The Front Door Triangle Sealing Strip L/R is a small but crucial weatherproofing component located at the front corner of the vehicle's door frame, typically where the side mirror attaches or at the A-pillar/door junction. This rubber or thermoplastic seal prevents wind noise, water leaks, and dust intrusion into the cabin. It also contributes to the vehicle's aerodynamic efficiency by reducing air turbulence around the door area. The "L/R" designation indicates side-specific parts that are precisely contoured to match the mirror base and door frame geometry on each side of the vehicle.
