This bolt-on knife fits 47° and 50° shanks. The top hole is slotted to fit 1 3/4" - 2 1/4" (45-57 mm) bolt hole spacing.  The tubes on this holder accept 1 1/4" (31mm) O.D. and 1 1/8" (28mm) O.D. airhose.  An insert, 880-BSH-1130, is included for use with the 1 1/8" inch hose.

This knife also provides maximum flexibility as it can be used with any of the Category 1 replaceable tips.  That means you can go from a narrow 3/4 inch tip right up to a 4 inch spread tip.  In certain conditions, corrosion may make removal of this replaceable tip difficult.  We recommend an anti-seize product be applied to the tongue of the holder prior to the tip being installed. This will ensure easy removal of this tip when it is being changed.
