Perko offset cam bar number 4 has a 3/8" threaded shaft to suit newer style locks and latches. As such this cam bar will not fit the older 'square shaft' Perko latches.
Typical flush lock and latch applications for the Perko 109100488A cam bar include:
• Perko 1091 & 1092
• Perko 1094 & 1095
This cam bar measures 73mm (2-7/8"). This measurement is taken from the centre of the lock set to the end of the cam bar shaft end. The Perko 1091, 1092, 1094 and 1095 locks & latches have an offset shaft so you will need to add 15.9mm (5/8") when measuring for your application.
