"Designed to safely span the gap between loading docks, freight truck trailers, dry vans or box truck beds, the 48"" x 72"" Guardian Steel Dock Board supports forklift operation with a maximum weight capacity of 16,000 pounds (forklift and load combined). This size accommodates a height differential of 5"" high. The high-visibility, bright yellow welded steel curbs on each side help line up forklifts during docking. Each dock board has built-in lifting loops that flip up when it’s time to move into position or off the dock with a forklift."
