Tilt these trucks back onto the rubber stair-climbing rollers to easily move loads up and down stairs. They have padded contact surfaces to protect loads and a strap with ratchet-style tensioner to secure them in place. 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.
Aluminum trucks are lighter than steel trucks.
Steel trucks are more durable than aluminum trucks. They have an automatic recoil mechanism that stores excess strap.
