Unistrut (“strut”) also has trolleys that roll in the track (1). Very useful for overhead roller systems in a workshop. Be very mindful of fastener clearances if installing one. I don’t have the handheld, portable bandsaw (“portaband”) that tradespeople usually use to cut strut, so I use a grinder with a cutoff wheel (noisy) or a sawzall with a metal cutting blade (more civilized).
