Our rubber speed bumps are the perfect way to control your busy parking lot or other high traffic area. These durable speed bumps 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 2,500 lbs. Our rubber speed bumps also include a channeled bottom for cabling, piping, etc. For increased visibility, they have reflective ''cats eyes'' built in. 12'' lag bolts included for simple installation.
