Frequently Asked Questions
What is the difference between QD and taper-lock bushings?
QD (Quick Detach) bushings are the North American standard (Dodge/Browning/Martin) with split flange and bolts that both install and extract the bushing. Taper-Lock is the European standard (Fenner/Dodge UK) with a simple tapered sleeve and separate extraction holes. Both provide taper interference fit. QD is more common in North American industrial applications.
