Designed to suit door openings up to 8' W x 10' H (2438mm x 3048mm) to 9' W x 10' H (2743mm x 3048mm), the Adjustable Head Pad Dock Seal's design can accommodate a variety of trailer heights. The foam head pad is raised and lowered on a track roller system while the torsion spring with integral follower curtain makes it easy to create a tight seal. By sealing all gaps that could let in water or dust, the Adjustable Head Pad Dock Seal protects employees and cargo during the cross-docking process.
