Device types in this collection

• Rim devices latch into a strike on the frame or a mullion, and suit single doors or pairs with a mullion.
• Vertical rod devices, surface or concealed (27 and 47 in the model number), latch at the top and bottom for pairs without a mullion.
• Mortise devices work with a mortise lock case in the door edge.

The 98/99 Series has the widest range of options here. 33A/35A devices are made for narrow stile doors. Read choosing an exit device for more detail.

Reading the model number

Suffixes describe the outside function: EO is exit only, DT is dummy trim, NL is night latch, TP is thumbpiece and L is lever trim. An F suffix means fire exit hardware, which has no mechanical dogging. Trims such as the 996L and 990NL are listed separately, so pick the trim that matches your device series and handing.

Sizes and finishes

Devices come in 36" and 48" lengths, cut to suit the door width. Finishes include 26D satin chrome, US3 bright brass, 643E aged bronze and 313 dark bronze anodized. For other brands, see all exit devices and trims.
