Detex 101478 – Frequently Asked Questions

1) What exactly is the Detex 101478 and what does it do on an exit device?
The 101478 is a shaft extension assembly, a replacement part that sits inside the trim side of a Detex exit device and carries the turn of the outside trim through to the device. It is not a complete trim and not a lock body, it is the drive shaft assembly. You order it when the original shaft extension is worn or damaged and the trim no longer operates the device reliably.
2) Which Detex trim does the 101478 shaft extension work with?
It is built for 08 and 09BN trim configurations on Detex exit devices. If the pull or lever trim on your opening is a different Detex trim series, this is the wrong shaft extension, so confirm the trim number stamped or documented on the existing hardware before ordering.
3) Is the Detex 101478 an OEM part or an aftermarket copy?
Genuine Detex OEM. That matters on a shaft extension because the length and end geometry have to match the device prep exactly for the trim to throw the mechanism, and it keeps the repaired device to original manufacturer specification.
4) My Detex exit device pushes open from inside but the outside lever turns without retracting the latch. Is the shaft extension the fix?
That symptom points at the trim drive train, and on a Detex device using 08 or 09BN trim the 101478 shaft extension is the part that transfers that motion. A worn, sheared or wrong-length shaft extension gives you exactly that, free-spinning trim with a device that still works from the inside. Replace the shaft extension assembly before you replace the whole trim or device.
5) Do I need to order anything else with the 101478, or does it come as a complete assembly?
The 101478 ships as an assembly, so it is not a loose shaft you have to build up. It does not include the trim itself or the exit device, so if the lever, escutcheon or cylinder is also damaged those are separate Detex parts.
6) Can I use the 101478 on a residential door, or is it commercial only?
It is a commercial-grade part, made for Detex exit hardware in commercial openings, offices, schools, healthcare, retail, warehouses, multi-tenant residential buildings and government facilities. Residential doors typically do not carry panic hardware at all, so there is normally nothing for this shaft extension to go into.
7) How do I order the right part, and what is the Detex model number for this shaft extension?
Order it by Detex model 101478. There is one configuration, no finish or length options to pick, so the only thing to verify is that the device it is going into uses 08 or 09BN trim.
