TTB Type
Product Description
Designed for thin template jig plates from 3/64″ to 3/8″ thick. Bushings are held in place by a threaded retainer ring. Left-hand thread is self tightening during drilling to prevent the retainer ring from loosening. OD serrations prevent the bushing from rotating during drilling. Choose standard countersunk type for flush mounting, or flanged type for installation without countersinking the jig plate.
