DS Series trucks put deep steel trays on wheels, with a raised lip on every shelf, so parts, hardware, and in-process work ride contained instead of sliding off flat shelves. Tray depths of 3", 6", or 12" (top tray) match the size of what you carry.
Tray footprints run 18" x 30" to 24" x 48". Trucks with 5" polyurethane casters carry 1,200 lbs.; heavy-duty 6" caster models carry 3,600 lbs. All-welded Little Giant steel construction by Brennan Equipment keeps trays leak- and rattle-free.
