Description

Mahr Federal, CR-20010-W42, 2.9375" x 4.2500" / 74.61mm x 107.95mm Collar Stop

Ring style Stop collars limit the depth a measuring head can be inserted into a bore. They are clamped onto the measuring head and are adjustable to set contact depth. Stop collars improve performance by assuring the same depth is measured consistently. Additionally, they help with alignment when plugs are used with shallow bores.

Special stop collars are available for diameters greater than 76mm/3". They provide the same function as the ring style except their design helps to reduce weight and can be used to set depth in deep holes.
