Some of the components are plastic
This is not a heavy duty application what so ever . One of the flanges broke . We do not recommend this product

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.
