Frequently Asked Questions
Q: What is the dentil mechanism and what does the dentil shaft do?
A: The dentil mechanism is a latch or indexing system used in hoist-type commercial door operators to positively hold the door in position. The dentil shaft carries the latch or cam element that engages notches or teeth on the drive to lock the door against uncontrolled movement.
Q: Is the 108855.0001.S a complete assembly or just the shaft?
A: The 108855.0001.S is a shaft assembly, meaning it includes the dentil shaft and the attached dentil cam, latch, or engagement element as a pre-assembled unit ready for installation. Individual shaft and latch components may also be available separately.
Q: What other dentil mechanism parts are available for service?
A: Related dentil mechanism service parts include the dentil spring (108122), the dentil component (111110), and associated hubs and sleeves. Refer to the operator parts diagram to determine which components require replacement.
Q: What happens if the dentil shaft assembly fails?
A: A failed dentil shaft can cause the door to drift or creep from its set position under load, fail to latch properly in the open or closed position, or produce clicking or grinding sounds during the dentil engagement sequence.
Q: What safety precautions should I follow when replacing the dentil shaft assembly?
A: Disconnect and lock out power, safely support the door in position before disengaging the dentil latch, extract the worn dentil shaft assembly, install the new 108855.0001.S assembly, and verify proper latch engagement and spring tension before restoring operation.
