Skid resistant safety tread deck. Bevelled edges allow smooth access from either end. Bend at upper end permits both ends of plate to lie flat. Steel legs fit between dock and truck; prevent movement when in use. High tensile aluminum alloy construction; no welds to break. HOW TO ORDER: 1. SELECT DOCKPLATE WIDTH: Add 12" to width of equipment to be used on dockplate. 2. DETERMINE HEIGHT DIFFERENTIAL: The vertical distance from dock floor to truck floor. The height differential decides the necessary plate length. 3. SELECT THE NECESSARY CAPACITY. COMBINATION BOARDS For a height differential exceeding 11", use a ramp in combination with dockplate. Each plate can be converted to an equivalent-size ramp. Call us with your requirements (866) 822-3901.
