The Detex 101812-1 is the OEM HD (Hex Dogging) fillerplate in 36-inch length for the Detex Value Series V40 and V50/V51 exit devices. "HD" in the Detex Value Series parts catalog stands for Hex Dogging -not heavy duty. This is the fillerplate body specifically designed for the hex dogging configuration of the V40 rim device and V50/V51 surface vertical rod device. It is item 10a in the Detex Value Series HD parts breakdown, and it is not the same fillerplate as the standard (non-dogging) or cylinder dogging (CD) configurations. Confirm the installed dogging type before ordering.

The 101812-1 is the 36-inch (3-foot) device version. The companion 48-inch (4-foot) version is 101812-2. Both carry the same HD hex dogging fillerplate function across the V40/V50/V51 device families.

What "HD" Hex Dogging Means on Detex Panic Hardware

Hex dogging is a function on exit devices that allows the push bar to be held in the depressed (latched-open) position using a hex key. When the hex key is inserted and turned, it dogs the push bar down, effectively disabling the exit device latch for as long as the dog is engaged. This allows the door to be opened from outside by trim (lever, thumbpiece, or knob) without having to depress the push bar each time.

Hex dogging is used on high-traffic commercial doors where the latch engagement on every entry would slow pedestrian flow or cause excessive wear on the exit device mechanism. Loading docks, retail stockroom entries, hospital service corridors, and school building passages are common applications. The hex dogging mechanism requires a hex key (100450 in the Detex Value Series parts catalog) to engage and release -only personnel with the correct hex key can activate or deactivate the dogged state.

The fillerplate for the hex dogging configuration (101812-1) differs from the standard fillerplate because it must accommodate the die-cast hex dogging assembly (102216-4) and the dogging bracket spacer (100164) that mount within the fillerplate body. A standard fillerplate does not have the correct mounting provisions for these components.

Detex V40 and V50/V51 Fillerplate: HD Parts Breakdown

The Detex Value Series V50/V51 parts price list (PPL) breaks the hex dogging fillerplate assembly into four individual components under Item 10:

101812-1 (Item 10a) = Fillerplate, HD, 36" -the structural body of the fillerplate (this product).

100164 (Item 10b) = Spacer, dogging bracket -positions the dogging assembly correctly within the fillerplate mounting.

102216-4 (Item 10c) = Die cast dogging assembly, Hex Dogging (HD) -the mechanical hex dogging mechanism that sits in the fillerplate.

PP-5802-124 (Item 10d) = Screw, 10-32 x 1-1/2" PFH -the fastener securing the dogging assembly to the fillerplate.

The complete pre-assembled kit (Fillerplate Subassembly, S&R, Hex Dogging, HD, 36") is part number 103806-15 and ships all four items together as a Service and Replacement unit. The 101812-1 is the fillerplate body only -for installations where only the structural body needs replacement and the dogging mechanism (102216-4), spacer (100164), and fasteners are undamaged and reusable.

Detex Exit Device Fillerplate Family: HD vs CD vs Standard

The Detex Value Series fillerplate family spans three dogging configurations. The 101812-1 (HD) and 101812-2 (HD, 48") are for hex dogging installations. The 102194-1 (CD, 36") and 102194-2 (CD, 48") are for cylinder dogging installations, where a mortise cylinder in the fillerplate is used to engage and release the dog rather than a hex key. Standard (non-dogging) Value Series devices use a separate base fillerplate without the dogging provisions entirely.
