Reviews
"It is as described and works well."
"good material somewhat pricey and shipping was on the slow side."
"Unistrut is just incredibly strong and versatile as structural support for just about anything. The number of compatible accessories in the Unistrut line fills pages, and I use it for shelf brackets, table and bench legs, light fixture support, conduit support, duct support, and just about anything else you can think of. For example, The little Milwaukee M12 band saw, only $139 at Home Depot and a dynamite little saw, has an opening EXACTLY 1 5/8x 1 5/8, which is EXACTLY the cross section of the full size Unistrut."
"The track pulleys which Unistrut offer (same company) hardly match the dimensions of these track beams."
"Arrived as a silver galvanized versus as a black enamel as described.... quite disappointed but tome crunch required it be used."
