The Slab from AME International comes as a cribbing item used to stabilize machinery during repair or maintenance, to its product line. Made of 55 lbs of recycled plastic and high density polyethylene measuring 6" thick, 12" wide and 24" long, the crib comes sturdy enough to handle the jobs that would splinter, crack, split and/or break wood cribbing. Its triangle patterned surface provides interlock traction at various angles and connects with smaller cribs, making it easy to stack multiple pieces to create large platforms 4' to 6' feet high.
