There's a lot there. This is NOT a set of 3 as the description and picture would suggest. This is the ONLY mount that holds 4 wheels connected with some kind of tube. most likely ABS pipes. So you need to order 3 of them for one tripod. Not the smoothest of the mechanisms in my opinion. Strong metal, nuts and bolts but the wheels lack the smoothness that makes the purchase ideal. I keep the ones I bought and take others closer from other sources.
