Flexible dock seal GapMaster™

loading

The impactable GapMaster dock shelter is a full-access enclosure that provides high sealing efficiency. It can prevent the loss of expensive energy through exposed trailer door hinge gaps, and reduce intrusion of outside elements into your facility. Fully impactable side frames protect the unit from damage from backing trailers. Full, unobstructed access to trailer loads by sealing the perimeter of the trailer. Rugged GapMaster™ hooks on curtains seal hinge-gaps on swing-out trailer doors. Provides dramatic energy savings. Also helps eliminate problematic "white space" at dock door openings, minimizing infiltration of dust and pests. HMWPE-wrapped foam side frames provide vertical stability and horizontal flexibility at extended projections ensuring maximum sealing effectiveness and longest product life. Slim profile (6" std, 152mm) side frames create a narrow footprint. Product fits tight spaces; can eliminate costly repositioning of lights, conduit, etc. Detachable side curtains allow easy removal and reattachment for ventilation or to replace or exchange curtains when needed. Fabric canopy header is independent of side frames, preventing damage to side frames and sagging of header under snow loads. Integral, fabric-wrapped rain gutter diverts water off sides of shelter. Header pivots to avoid damage if trailers back in off-center or higher than expected. Available with high-strength Durathon™ fabric - friction-resistant, high-wear fabric for added life. Available with Firefighter™ heat dissipating protection in head curtain to prevent burning from heat of trailer marker lights.
