Stafford’s Staff-Lok™ lever actuated shaft collars can be opened, moved, and re-clamped by hand for use in larger, non-rotary applications. No tools required.

These collars feature an integral hinge with a conformal cam lever for clamping and a knurled nut for adjusting the clamping preset, which makes it easy to move by lifting the lever, moving the collar, and clamping it by hand.

Machined from steel with a smooth bore, Staff-Lok™ Shaft Collars come in three body and round bore size combinations: 2-1/8” O.D. with 1/2”, 5/8”, 3/4”, 7/8”, and 1” bores, 3- 1/4” O.D. with 1-1/8”, 1-1/4”, 1-1/2”, and 1-3/4” bores, and 4-1/4” O.D. with 2”, 2- 1/4”, and 2-1/2” bores.

Specials are offered with different bores.
