Sargent AD8410-F Narrow Stile Concealed Vertical Rod Exit Device, for Aluminum Doors - Exit Only - 36"

About this item

The Sargent AD8410-F is the go-to concealed vertical rod exit device for narrow stile aluminum storefront doors in commercial buildings. Architects, general contractors, and facility managers specify it by model number because it solves a problem that rim devices and surface-mounted hardware can't: it latches at both the top and bottom of the door while keeping every rod hidden inside the stile. The result is a full glass storefront door that meets building code life safety requirements without any visible hardware running up or down the face of the door.

This is the F-size rail, which fits door widths from 33" to 36". It ships as an exit-only device, meaning there's no outside trim. Anyone pushing from the inside exits freely. No one enters from the outside without a separate access device. That's the correct specification for secondary egress doors, stairwell exits, and controlled exit points in retail centers, schools, and government buildings.

What Makes the Sargent AD8410 a CVR Exit Device Specification Standard

The AD8410 is part of Sargent's 80 Series exit device platform, the same family that covers rim, mortise, and surface vertical rod configurations. The concealed vertical rod design places both the top and bottom latching rods inside the door stile cavity. This protects the rods from tampering, vandalism, and everyday abuse while keeping the door profile clean. Stile must be hollow with an inside dimension of at least 1-3/8" (35mm) square to accept the device. Minimum stile width is 1-3/4" (44mm).

Hex key dogging is standard on this non-fire-rated configuration. If you need cylinder dogging, specify the 16-AD8410 prefix. For electric latch retraction, request the 56-AD8410. Request-to-exit signal monitoring uses the 55- prefix. Electric dogging uses 58-. All electric options integrate with access control systems without compromising the panic-compliance of the base device.

The NB Option: No Bottom Rod for Wheelchair and Cart Access

Specify NB-AD8410-F when the application requires free bottom clearance for wheelchairs, carts, or equipment. The NB configuration removes the bottom rod and bottom strike entirely. This eliminates the tripping hazard from the bottom strike plate and meets ADA accessibility standards for high-clearance thresholds. It's a common specification on loading dock egress doors and accessible building exits.
