Double-Acting Ball Lock Pins (T Handle)

Ball Lock Pins & Quick-Release Pins

Product Information

T Handle

Double-Acting Ball Lock Pins are positive locking until released by either pushing or pulling the center spindle, which is connected to the handle. Pushing on the handle releases the balls and inserts the pin in one motion. Pulling on the handle releases the balls and removes the pin in one motion. Ball Lock Pins are high-strength, quick-release alignment pins with a precision ground shank and positive locking. The T-handle version shown here is one of three available handle styles. Made in USA.

Available in pin diameters from 3/16 to 1" (5 to 20mm in metric), in stainless steel only. All Double-Acting Ball Lock Pins are made to order, with standard grip lengths for each diameter listed in the tables below. Pins with special grip lengths up to 12” (300mm) and other special features can also be quickly made to order. The Part Configurator link at the top of this page can be used for any Double-Acting Ball Lock Pin, either standard or special.

Technical Information

Double-Acting Ball Lock Pins are positive locking until released by either pushing or pulling the center spindle, which is connected to the handle. Pushing on the handle releases the balls and inserts the pin in one motion. Pulling on the handle releases the balls and removes the pin in one motion.

Optional Drive Out

Double-acting pins are available with a "Drive-out" option, where the center spindle extends slightly beyond the shank end (see M dimension). This allows removing a pin under slight shear load by tapping the end with a hammer (releasing the balls at the same time). Add "-D" to the part number:

CL-4-BPDT-1.50-S-D

Optional 4 Ball

Pins are optionally available with four balls instead of two, for more-distributed ball-pullout force. Add "-4BALL" to the part number:

CL-4-BPDT-1.50-S-4BALL

Optional Cable
