The Detex 100696-1 is the OEM BP2 narrow stile mounting plate for four Detex exit device series: the Advantex 10/40 rim device, the Advantex 20/50 surface vertical rod device, the Value Series V40 rim device, and the Value Series V50/V51 surface vertical rod device. The mounting plate is the first component installed on the door during exit device installation. It mounts directly to the door face and serves as the structural base that the exit device body mounts over, the strike locator that positions the matching strike on the door frame, and the door face reinforcement that distributes exit device load across a wider surface area than the device fasteners alone.

The BP2 designation identifies this plate as the narrow stile configuration within the Detex Backplate family. The BP numbering (BP2 through BP8) spans multiple stile widths and finish configurations across the Detex product line. Confirm BP2 narrow stile is the correct designation for the installed device before ordering - wide stile applications use a different mounting plate.

Detex V40 and Advantex Mounting Plate System: Patented Strike Locator

The Detex mounting plate system is a patented feature of the Advantex and Value Series exit device families, explicitly described by Detex as providing the easiest and most accurate installation of panic hardware available. The plate's strike locator is a built-in alignment feature - it positions the matching strike plate on the door frame precisely relative to the mounted exit device on the door face, eliminating the guesswork of measuring and marking the frame strike location separately.

This strike locator function matters most in replacement and retrofit situations. When a mounting plate is damaged, corroded, or missing and a replacement plate is installed, the strike locator re-establishes the correct device-to-strike alignment without requiring a new template or field measurement. For a locksmith servicing a building with multiple V40 or Advantex devices, this alignment system reduces installation time and eliminates mis-strikes from human measurement error.

Detex Exit Device Series That Use the 100696-1 Mounting Plate

The BP2 narrow stile mounting plate is shared across both the Advantex and Value Series product families in narrow stile configurations.

The Advantex 40 Series is Detex's super-heavy-duty narrow stile rim exit device, Grade 1, for all types of narrow stile single and double doors with mullions. The narrow stile design accommodates aluminum storefront and glass doors where the stile width is too narrow for standard wide-body exit devices.

The Advantex 50 Series is the super-heavy-duty narrow stile surface vertical rod exit device for narrow stile double doors without a mullion. The SVR configuration requires rod routing inside the door to top and bottom latches, with the centercase surface mounted on the narrow stile.

The Value Series V40 is Detex's Grade 1 narrow or wide stile rim exit device at an economical price point. The V40 is designed for all types of single and double doors with mullions and uses the same patented mounting plate system as the Advantex family.

The Value Series V50/V51 is the narrow stile SVR variant in the Value Series product family, designed for narrow stile double door applications at the Value Series price point.

All four device series share the BP2 mounting plate (100696-1) for narrow stile applications.

Detex Panic Hardware: Narrow Stile vs Wide Stile Mounting Plates

Narrow stile glass and aluminum storefront doors present specific installation challenges for exit hardware that wide stile hollow metal doors do not. The stile width on a narrow stile glass door can be as small as 1-3/4" to 2", leaving very limited surface area for mounting fasteners. The Detex narrow stile mounting plate is dimensioned specifically for this application, providing correct hole spacing for the narrow stile doorframe while maintaining the full strike locator function.

The Detex Advantex 10/40 Series installation instruction (Detex document 104881) references the full BP mounting plate family - BP2, BP3, BP5, BP6, BP7, and BP8 - each corresponding to a specific configuration, finish, or stile application. The 100696-1 is the BP2 version, and the correct finish code must be confirmed against the installed device specification at time of order.
