Ron, Hand transportable Dock Plates are roughly 48 x 48 and weigh just under one hundred pounds. The Safety Legs(those two prongs hanging down) are located about eleven inches from track side - forty-seven from the dock side. Allowing for maximum slippage when the fork lift truck approaches the dock plate, the greatest distance between the edge of the dock and the edge of the box car can be ten inches. John
