Flexible dock shelter GapMaster™

Overview
This impactable dock shelter GapMaster™ is a full‑access enclosure designed to provide a complete perimeter seal for trailers, including hinge and swing‑door gaps. It prevents energy loss through exposed gaps and reduces intrusion of weather, dust and pests while allowing unobstructed loading access.

Key Features

• Impactable side frames protect the shelter from damage caused by backing trailers.
• Full, unobstructed access to trailer openings while maintaining a perimeter seal.
• Rugged GapMaster™ hook‑shaped curtain edges seal hinge gaps on swing‑out trailer doors to reduce energy loss and white space at the dock opening.
• HMWPE‑wrapped foam side frames provide vertical stability and horizontal flexibility at extended projections for effective sealing and longevity.
• Slim side‑frame profile (6" standard, 152 mm) minimizes footprint for tight dock areas and can avoid repositioning nearby fixtures.
• Detachable side curtains allow easy removal for ventilation or curtain replacement.

Header

• Independent fabric canopy header prevents damage to side frames and avoids header sag under snow loads.
• Integral fabric‑wrapped rain gutter diverts water away from the shelter sides.
• Pivoting header accommodates off‑center or higher trailer approach to prevent impact damage.

Additional Options

• Available with high‑strength Durathon™ fabric for increased abrasion resistance and service life.
• Available with Firefighter™ heat‑dissipating protection in the head curtain to prevent burning from trailer marker light heat.
