Plastic or rubber speed bumps and speed humps are used for traffic calming in private streets, parking lots and access roads. Speed humps are shallower and wider (in the direction of travel) than speed bumps.
The SP18-716 is the recommended anchor for this application. We suggest that you apply anti-seize grease to the bolt before securing the bump. The reason is that the rubber bumps wear out over time and need to be replaced. The bolts may rust and make it impossible to remove, unless the anti-seize paste has been applied.
For extremely tough applications, where continuous trucking traffic pounds the bumps and requires their constant replacement, contact us about our SP58 anchors. These have a 5/8" internal thread. Ths SP58 is available as a special order only.
