GapMaster hooks
Impactable side frames
Pivoting canopy header


  • 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.
