Model 250 Interior Sliding Ladder Racks mount on the inside roof of a van or truck with a metal cap or an enclosed trailer, and allow users to load up to an eight-foot A-frame or extension ladder. Also available, Weather Guard Bulkhead and shelving systems universally fit Ford and Chevy vans, and feature strong 16-gauge steel construction and 3/16-inch steel top mounting angles. A nine-inch by 12-inch Dog Hatch in the bottom of the bulkhead allows easier and safer transportation of long-length material.
