Marine Ball Lock Pins are similar to the standard single-acting Ball Lock Pins, and even have their handle made of stainless steel (instead of aluminum) for extra strength and corrosion resistance. Ball Lock Pins are high-strength, quick-release alignment pins with a precision ground shank. They are positive locking until released by pushing the button, which moves the center spindle forward to allow the balls to retract. Made in USA.

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

To order pins with a standard cable assembly attached, add "-C" to the part number. For an optional 10" nylon lanyard, add "-NL" to the part number.
