In addition to rotating rubber stair climbers on the back, these trucks have fold-down rear legs for increased stability when moving loads up and down stairs and over curbs. They have padded contact surfaces to protect loads and a strap with ratchet-style tightener to secure them in place. An automatic recoil device stores excess strap. Their rubber tread-on-core wheels have a hard core for strength surrounded by a shock- and sound-absorbing tread for a cushioned ride on all surfaces.
