An expanded line of lever actuated shaft collars that can be opened, moved and re-clamped by hand for use in larger, non-rotary applications is being introduced by Stafford Manufacturing Corp. of Wilmington, Massachusetts. Staff-Lok™ Shaft 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.  Eliminating the need for tools, this line of lever actuated collars has been expanded to include larger body and bore sizes. 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 or materials.
