Least expensive option and best for my application
Used to make a home made holder for to attach the spare tire to my jeep. Welded directly to the body, not bolted. The last few months have held up great and dealt with some abuse at the track. No complaints!
Pros
HEAVY DUTY: Locking design allows for instant clamping and unclamping of the workpiece while providing fine adjustment of mounting distance and clamping force
