Vent Division Bar Weatherstrip

This Front Vent Division Bar Weatherstrip is designed to fit opposite the glass run channel, sealing your vent window tightly when closed. Made from top quality rubber with a corrosion-resistant brass metal core and attaching tabs, it ensures a durable, proper seal to keep out drafts and moisture.

Sold as a pair for both driver (LH) and passenger (RH) doors, it replaces factory parts #4090509 and #4090510, guaranteeing a precise fit for your vintage Buick, Cadillac, or Oldsmobile.

• Fully molded rubber with brass metal inserts for long-lasting durability
• Includes both left and right side weatherstrips
• Handcrafted in the USA for guaranteed fit

Installation is straightforward: remove the old weatherstrip from the vent division bar, align the new part with the metal core and tabs, then press firmly in place. This provides a reliable seal that reduces wind noise and prevents water leaks.
