Detex SN1 – Frequently Asked Questions

1) What thread size are the Detex SN1 nuts?
The Detex SN1 nut kit uses 1/4-20 threading, meaning a 1/4 inch diameter with 20 threads per inch. Any mounting screw or stud on your Detex exit device that measures 1/4-20 will take these nuts. Two nuts come in the kit.
2) Will these Detex nuts work on my Von Duprin or Marks USA exit device?
The SN1 nuts are made as replacement fastening hardware for Detex exit devices, specifically vertical rod devices and related Detex hardware. For a Von Duprin 88 Series surface vertical rod device or a Marks USA M9900VR, use the fastener pack that belongs to that device rather than a Detex part. Match the fastener to the device brand and you avoid stripped or mismatched threads.
3) Is the Detex SN1 a complete exit device or just a part?
It is a parts kit, not a device. The SN1 is two 1/4-20 nuts used for fastening and mounting Detex exit device hardware. If you need the actual panic hardware for the opening, you are looking for a surface vertical rod exit device such as the Von Duprin 8827-3FT or the Marks USA M9900VR, not this kit.
4) How many nuts come in the Detex SN1 kit?
Two. If you are servicing several openings in a building, order one kit per pair of fasteners you plan to replace rather than expecting a bulk bag.
5) I need to re-secure a loose vertical rod exit device. Is this the right hardware?
If the looseness is at a 1/4-20 fastener on a Detex device, yes, these are the replacement nuts for it. They are intended for field service and repair work on Detex exit device hardware in commercial buildings, schools, healthcare and government facilities. Check the thread on the existing fastener first; anything other than 1/4-20 needs a different nut.
6) If I am replacing the whole exit device instead of just the fasteners, what fire rated vertical rod options are there?
For a fire rated opening you need a device that is listed as fire rated, and a nut kit plays no part in that. Fire rated surface vertical rod options include the Marks USA M9900FVR for a 36 x 84 door, the M9900F-VR for 48 x 84, and the Delaney F9100 Series Grade 1 for a 36 x 84 door. Non-rated vertical rod devices such as the Delaney 9100 Series or Cal-Royal 9860 should not go on a fire door.
7) The door with the loose exit device hardware is fire rated - do I need a different nut kit?
Fire rating is a property of the exit device assembly, not of a 1/4in-20 fastener, so the Detex SN1 nut kit carries no rating of its own. What matters is that the device itself is a labeled unit: the Delaney F9100 Series vertical rod device for a 36 in by 84 in door is fire rated and Grade 1, as are the Marks USA M9900FVR at 36 in by 84 in and the MARM9900F-VR at 48 in by 84 in. If the existing device is not a labeled one, replacing fasteners will not make the opening compliant.
8) Is a Grade 2 exit device like the Cal-Royal 9860 an alternative to buying the Detex SN1 kit?
They answer different needs. The Detex SN1 supplies two 1/4in-20 nuts for refastening or servicing exit device hardware in place. The Cal-Royal 9860 is a complete surface vertical rod device, heavy duty, ANSI Grade 2, exit only and not fire rated - a replacement for the whole device rather than a service part. Choose the 9860 when the device itself is being swapped out and the opening does not require a labeled assembly.
9) My opening is a 48 inch leaf - what vertical rod devices cover that width if I am replacing rather than repairing?
The Detex SN1 nut kit is width neutral since it is just fastening hardware. For a 48 inch by 84 inch leaf, the Marks USA M9900VR 48 in by 84 in is a non-fire-rated exit only vertical rod panic device, and the MARM9900F-VR M9900F at 48 in by 84 in is the fire rated exit only version of the same style. Narrower 36 inch leaves are covered by devices such as the Delaney 8100 Series Grade 1 vertical rod device for a 36 in by 84 in door.
