Double Acting Pins are activated by pull or push motion and are ideal for quick removal and insertion. When the handle is pushed, the locking balls release and and the pin can be placed in one, easy motion. Similarly, pulling on the handle releases the locking balls and the pin can be removed swiftly. The stainless steel build gives corrosion resistance for increased durability. All of our Double Acting Pins meet or exceed NASM 23460 and MS17989 design specifications. Monroe offers an optional drive out feature, for removing pins under slight shear load, where the center spindle of the pin extends beyond the shank end. Additionally, four ball options are available upon request.
