Unistrut Trolleys are uniquely designed to work with the 1-5/8" wide Unistrut profiles, P1000/P1001/P5500/P5501/P5000/P5001.  

Unistrut Trolley systems can be designed to move equipment from 10 lbs to 600 lbs (higher loads can be reached with multiple trolleys) with reliability, ease, and economy.  Unistrut trolleys utilize steel or acetyl wheels with corrosion-free stainless steel wheel bearings, that require no lubrication.  The trolley systems are composed of three basic elements- trolleys, Unistrut track, and threaded rod supports.
