Extension Shaft
Mechanical shaft for transmitting rotation between an internally mounted device and an external rotary handle.
An extension shaft is used in door-coupled operators and other mechanical systems for remote manual operation of a device.
Its profile and across-flats dimension must match both the device operating mechanism and the selected handle.
In many systems the shaft is supplied with excess length and may be cut during installation to suit the required cabinet depth.
Selection criteria include shaft profile, across-flats size, length, cut-to-length capability, material and mounting position relative to the device.
Extension shafts for door-coupled handles and rotary operating mechanisms.
