Detex DTX-NSK-628-71 – Frequently Asked Questions

1) Will a Detex V40 or V50 exit device mount on a 2 inch narrow stile aluminum door?
Not on its own. Standard V40 and V50 Value Series rim devices need the Detex NSK narrow stile conversion kit to land correctly on doors with a 2 inch minimum vertical stile. The kit supplies the mounting and alignment components that let the device sit on the narrow stile of an aluminum storefront or glass door while keeping the panic function working.
2) What door widths does the Detex NSK narrow stile conversion kit cover?
It is laid out for 36 inch and 48 inch wide doors. If your storefront leaf falls outside those two widths, this kit is not the right part for the opening.
3) Do I have to replace my existing Detex exit device to convert it for a narrow stile door?
No. The NSK kit is a field-installed conversion, so an existing V40 or V50 rim device stays on the job and only gains the narrow stile mounting and alignment hardware. That is the point of the kit for a retrofit where the storefront stile is too narrow for a standard rim mount.
4) The opening needs a fire rated vertical rod device. Is the Detex narrow stile conversion kit the right part?
The NSK kit is a mounting and alignment kit that adapts V40 and V50 Value Series rim exit devices to narrow stile doors; the fire rating comes from the device and the door assembly, not the kit. If the job calls for a fire rated vertical rod device outright, the Delaney F9100 Series device for a 36 inch by 84 inch door is Grade 1 and fire rated, and Marks USA offers the M9900FVR at 36 inch by 84 inch and the M9900F-VR at 48 inch by 84 inch, both fire rated exit only.
5) If the door has a wide stile instead of a 2 inch narrow stile, what vertical rod exit device should be used?
The Detex NSK narrow stile conversion kit is built for aluminum and glass doors with 2 inch minimum vertical stiles, so it does not apply to a wide stile opening. For wide stile doors, the Von Duprin 8827-3FT is a Grade 1 surface vertical rod device listed as wide stile for a 3 ft door with a 1-3/4 inch door thickness, and the Imperial USA ED-VR531 is a Grade 1 surface vertical rod exit only device for a 36 inch door, also listed as wide stile. Those are complete devices rather than a retrofit kit.
6) Is the opening still code-compliant panic hardware after installing the Detex narrow stile kit?
The kit is the OEM Detex conversion, and it keeps the V40 or V50 operating as full panic hardware after installation. Nothing about the exit function is disabled or bypassed by the narrow stile mounting.
7) What is actually in the Detex NSK conversion kit?
All the mounting and alignment components needed to set a standard V40 or V50 rim device onto a narrow stile door, built from aluminum and steel hardware. The exit device itself is a separate purchase; the kit adapts it rather than supplying it.
8) Instead of retrofitting an existing exit device with the Detex conversion kit, what non fire rated vertical rod devices cover 36 inch and 48 inch doors?
The Detex NSK kit covers 36 inch and 48 inch doors by converting a V40 or V50 device already on the opening. To buy the device complete instead, Marks USA lists the M9900VR vertical rod panic device in 36 inch by 84 inch and in 48 inch by 84 inch, both exit only, non handed, and non fire rated. Delaney's 9100 Series Grade 1 heavy duty vertical rod device covers a 36 inch by 84 inch door in a stainless steel finish, also non fire rated.
9) Does the Detex NSK conversion kit change the ANSI grade of the opening, and what Grade 1 or Grade 2 devices are the alternatives?
The NSK kit supplies mounting and alignment components so a V40 or V50 rim device sits correctly on a 2 inch stile; grade is carried by the device itself. Among complete vertical rod devices, the Cal-Royal 9860 is a heavy duty Grade 2 exit only device, while the Delaney 8100 Series for a 36 inch by 84 inch door and the Von Duprin 8827-3FT in the 88 Series are both Grade 1. A facility standardizing on a stated grade would specify at the device level rather than through the kit.
10) Can a surface vertical rod device like the Von Duprin 8827 be substituted for the Detex narrow stile kit on a storefront door?
They solve different problems. The Detex NSK kit is an OEM accessory that lets an existing V40 or V50 Value Series rim device work on a narrow 2 inch stile aluminum or glass door without replacing the device. The Von Duprin 8827-3FT is a complete surface vertical rod device in the 88 Series, Grade 1, listed as wide stile for a 1-3/4 inch door. Ordering the 8827 in place of the kit means replacing the exit hardware and needing a stile that accepts a wide stile device.
11) What finish does the Detex narrow stile conversion kit come in?
628, also called US28, Satin Aluminum. That is the usual match for clear anodized aluminum storefront framing, so the conversion hardware blends with the door rather than standing out against it.
