Skatestopper

Skatestoppers are skate-deterrent or anti-skate devices placed on urban terrain features, such as benches and handrails, to discourage skateboarders from grinding on the surfaces where they have been installed.

[1] The name Skatestopper is a registered trademark of Intellicept of El Cajon, California,[2] but in some skateboarding circles it has become a genericized term referring to any anti-skate device.

[3] The most basic skatestopper design is an L-shaped bracket affixed at intervals along a grind-able structure.

Because the devices have been targeted for removal by skateboarders, there have been attempts to make skatestoppers tamper resistant.

The presence of skatestoppers can actually encourage skateboarders to stay in a location longer.
