Fall-arrest barrier Dok-Guardian® HD and HDXL

extendablemanualpolymer

Overview
The Dok-Guardian® HD and HDXL are manually operated, retractable loading-dock safety barriers that provide a visible physical edge barrier to help prevent pedestrians and material handling equipment from falling off open dock edges. Models are suited for heavy-duty industrial environments and can interlock with other dock equipment for safe operational sequences.

Key benefits

• Clear warning: High-visibility curtain and restraint straps highlight the dock edge and alert operators and pedestrians to the hazard.
• Fall protection: Designed to stop material handling equipment and personnel from falling off the dock edge.
• Integration: Can be interlocked with Dok-Lok® vehicle restraints and other dock systems to form safe sequences of operation.
• Ventilation: Allows outside air into the facility when no trailer is present while maintaining edge protection.

Safety & compliance

• Impact resistance: HD/HDXL heavy-duty variants are BLAST (Barrier Load and Speed Tested) rated; consult manufacturer BLAST charts for matching barrier to application.
• Interlock capability: Supports interlocking with Dok-Lok® and Dok-Commander systems for controlled access and safe loading/unloading.
• OSHA: The taller HDXL model is designed to meet OSHA guardrail requirements (OSHA 1910.29) for protection of a ~4 ft (≈1.2 m) drop-off.

Design
The system is manually operated and retracts into two anchor/store units (Wardens) when not in use. Curtains are high-visibility PVC-coated fiberglass (HD) or PVC-coated fiberglass mesh (HDXL) with horizontal and vertical restraint straps for recognition and restraint in busy dock environments.
