Detex 100783 – Frequently Asked Questions

1) What exactly is the Detex 100783, and what does it do inside an exit device?
The Detex 100783 is the cylinder nut for Detex EAX Series exit devices. It threads onto and retains the cylinder assembly in the device, holding the cylinder in alignment so the keyed function operates correctly. It is a genuine Detex factory replacement part, not an aftermarket equivalent.
2) My EAX alarmed exit device key cylinder is loose and spinning in the housing. Is this the part I need?
That is the usual symptom the cylinder nut fixes. If the cylinder turns or wobbles in the device rather than the lock failing, the retaining nut has backed off or is damaged, and the 100783 is the EAX Series part that clamps it back down. It restores cylinder retention without replacing the whole device.
3) Does the Detex 100783 include the cylinder, or is it just the nut?
Just the nut. The 100783 is the cylinder retaining nut on its own. If the cylinder itself is damaged or you are rekeying to a different keyway, you need to source the mortise cylinder separately, and the cylinder must match what the EAX device is prepped for.
4) Should I replace the whole EAX device or just order the cylinder nut?
If the alarm and latching still work and only the cylinder mounting is loose, the nut is the right call. It is a targeted replacement part that brings the device back to original working condition and keeps the door in service, which is cheaper and faster than pulling the device. Replace the full device only when the chassis, latch, or alarm module itself has failed.
5) Is the 100783 a commercial-duty part suitable for a school or hospital exit door?
It is classed as a commercial part, built for Detex EAX Series hardware in commercial service. Typical settings include office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and government buildings, all places where the exit device sees steady traffic.
6) I stock parts for several Detex EAX doors. Is this an OEM part I can standardize on?
Yes, the 100783 is a Detex factory part made to the manufacturer's own specification for the EAX Series, so the same part number covers every compatible EAX device in your building. That makes it straightforward to keep a few on the shelf for a fleet of alarmed exit doors.
