Three-Prong Knobs

Hand Knobs

Carr Lane three prong thermoplastic knobs are available tapped or with a tapped-through hole. Tapped three prong knobs are available in three sizes, with tapped hole sizes from 1/4-20 to 3/8-16, while tapped through three-prong knobs are available in a single knob size (2-1/2) and hole sizes of either 5/8-16 or 3/8-16. Whether tapped or tapped-through, Carr Lane three prong knobs are designed to provide quick-tightening and high levels of torque, featuring a molded-in brass insert for superior strength. Custom thread sizes, reamed holes, molded-in studs and special colors are available in quantities of 500 (tapped three prong knobs) and 250 (tapped through hole three prong knobs). All thermoplastic knobs manufactured by Carr Lane are proudly made in the USA.
