Our rubber speed bumps and speed humps are the perfect way to control your busy parking lot or other high traffic area. They are made from durable rubber and will conform to uneven pavement to make installation easy. They can be removed or replaced unlike permanent ones. They will not crack, warp or rot and can withstand up to 2,500 lbs. A channeled bottom for cabling, piping, etc makes them even more versatile. For increased visibility, they have reflective ''cats eyes'' built in. 12" lag bolts are included for simple installation. Optional end caps can be used to round off the outside edges of the bumps.
