Detex NSK-628 Narrow Stile Door Conversion Kit for V40 and V50 Series Exit Devices (Satin Aluminum, 628 Finish)

The Detex NSK-628 is a narrow stile door conversion kit that allows standard Value Series V40 and V50 rim exit devices to be installed on aluminum and glass doors with narrow 2-inch stiles. This kit is essential for adapting panic hardware to fit frameless glass or storefront doors where standard exit devices would otherwise exceed the available mounting surface.

Designed for use with 36" and 48" wide doors, the NSK-628 kit retrofits Detex V40/V50 devices by providing all necessary components to achieve proper alignment, support, and function on doors with 2" minimum vertical stile dimensions. The result is a code-compliant, secure installation without the need to replace the exit device.

Finished in 628 / US28 Satin Aluminum, the kit is ideal for matching existing hardware aesthetics and is built to Detex’s commercial-grade standards.
