These universals are fantastic and
last for years. The JCD Universal is a removable
machined socket that houses a swiveling rope-core
urethane joint. The joints swivels smoothly at
any angle and with zero play, eliminating the twisting
loads that cause universal failure. The device
is adaptable to 16mm (5/8") with sleeve and 20mm
sticks and is fixed to the stick with a single screw.
