The Vestil Vinyl Dock Seal 8 ft x 9 ft D-350 Series offers heavy-duty dock protection for high-use loading zones. With 3 thick, foam-filled pads and up to 5" of compression, this seal creates a secure connection between your building and the trailer door. Available in 10" to 20" projection sizes, it’s designed to fit flush docks or Edge-O-Dock setups. Install in less than 1 hour. 90 day manufacturer warranty. Nylon-reinforced 36 oz vinyl ensures a lifetime of safe docking. Available in projections from 10" to 20". D-350 Series Seal Combines Reinforced Vinyl Strength with Built-In Air Relief. Each seal is made with 36 oz. nylon-reinforced vinyl for superior tear resistance... even better than hypalon. Sealed ends stop moisture from penetrating over time, and air tunnels help safely release pressure when a trailer presses against the seal. You get clean, dry, draft-free sealing for your 8x9 dock opening in all weather conditions. Vestil D-350 Dock Seal Projections from 10" to 20" for Precise Trailer Fitment. Whether you need a 10" projection for tight docks or a 20" model for Edge-O-Dock compatibility, the D-350 series has you covered. Designed for doors up to 96" wide x 108" high, this system offers max compression without overstuffing your dock entry point. Top pad and side pads bevel in to guide trailers in and hold firm under contact. Installs Fast with the D-350's Pre-Assembled 3-Piece Seal Design. This model ships as a three-piece system. (two vertical side pads and one top flap) Includes a through-the-wall mounting kit and installation instructions. Durable wolmanized wood backing, air release tunnels, and reinforced yellow guide stripes make it both functional and long-lasting. Important Product Specifications.
