Corbin Russwin 376F37-626 – Frequently Asked Questions
1) What is a sex nut on an exit device, and what does the Corbin Russwin 376F37 do?
A sex nut is the threaded barrel that mates with the mounting screw through the door, so the exit device is clamped through the door leaf rather than held by wood or sheet metal threads. The 376F37 is the Corbin Russwin replacement barrel for ED7000 crossbar exit devices. If you are pulling an old device off and the through-bolt hardware is stripped, chewed up, or missing, this is the piece you re-order rather than the whole device.
2) Will the Corbin Russwin 376F37 sex nut work on a 2 inch thick door?
Yes. The 376F37 is sized for both 1-3/4 inch and 2 inch doors, which covers standard commercial leaf thickness and the heavier 2 inch openings. On doors thicker than 2 inch you need the longer through-bolt hardware for that thickness instead, since the barrel has to bottom out correctly for the device to clamp flat against the face of the door.
3) I manage a building with ED7000 crossbar devices on several doors. Can I stock this part for all of them?
If those doors are 1-3/4 inch or 2 inch leaves, one part number covers them. That is the practical reason to keep a few on the shelf: crossbar devices get re-hung and re-mounted over their life, and a stripped barrel otherwise takes a door out of service. Confirm the leaf thickness on each opening first, because a 2-1/4 inch door takes different through-bolt hardware.
4) Is the Corbin Russwin 376F37 suitable for commercial and institutional use, or is it a residential part?
It is a commercial part, built for the same ED7000 crossbar exit devices used in schools, healthcare, offices, retail, warehouses and government buildings. Exit device mounting hardware is a life-safety assembly component, so using the manufacturer's own barrel rather than a generic through-bolt keeps the installation as the device was tested and listed.
