Avdel Pip Pin
The 3201 original 'pip pin', manufactured by Avdel in England and now no longer in production.
The registered trade mark pip-pin® has become a general term for a ball lock fastener.
The 3201 series pip pin was a steel double action (push / pull) 2 ball pin with it's characteristic loop handle.
The pip pin was sized by diameter in 1/16" and grip in 1/10" and this number was stamped on the pin. Many 'special' variations were produced, our technical department can advise on many of the now obsolete pins.
The pip pin was originally supplied cadmium plated and was approved by AGS as AGS 2105-xxxx
