Tapered Unflanged Guards

Tapered Unflanged Machine Safety Guard

Tapered unflanged guards cover belt or chain drives with different sized sheaves or sprockets.

A tabbed backplate covers the back of the machine guard. Unflanged guards are mounted through the side of the guard and the tabs of the backplate, with extruded u-nuts that ensure fastening metal-to-metal.

Tapered Unflanged Guard Sizing

Note: MGC normal manufacturing policy does not include cutting holes for shafts or making brackets for mounting. This can be done on special orders.
