Quick answer: Double height guardrail uses 41.5″ steel posts with two rails at 17.61″ and 40.16″, so it blocks forklift forks and wheels and gives people a visible barrier at waist height. It is the usual choice for pedestrian walkways and work areas, and is rated 10,000 lb at 4 mph when properly installed. Starter kits start at $473 and add-on kits at $297.
Double height guardrail uses 41.5″H posts with two rails to create a taller, stronger barrier between forklifts and the people, racking and equipment around them. It is the go-to choice for high-traffic forklift aisles, loading docks, mezzanine bases and pedestrian walkways that sit next to active lanes.
Start a new run with the double height starter kit (2 posts, 2 rails and hardware), then extend it with add-on kits. Spare double height post kits and guardrail beams are available for custom lengths and repairs.
For lower-risk areas such as wall and equipment protection, compare our single height guardrail.
Use double height wherever people walk or work next to forklift traffic. Single height is enough for protecting racking and equipment.
No. It is designed and rated for vehicle impact, not as an edge guardrail. For mezzanines and dock edges, see our guide to OSHA guardrail requirements.
Two 41.5″ posts, two rails of your chosen length and the hardware kits, including wedge anchors.
