Barbell Clamp

thingiverse

Clamp speeds up barbell weight changes. Fits 1" barbell. Works great for bench press, shrugs, curls, etc. I would not use overhead e.g. - overhead triceps extension with dumbbells. It held 35 lbs of weights on barbell in vertical position. You made need to scale to properly fit your bar. 2" long 1/4-20 bolts and nuts required.
