A mortise exit device puts the latch inside the door, where it's protected from tampering and abuse. Shop Sargent mortise exit devices, including the Grade 1 8900 Series for wide stile wood and metal doors and the 8300 Series for narrow stile doors, in mechanical, fire-rated, and electrified versions with E, F, J, and G rails. In stock at Commercial Door Hardware.

Why Choose a Mortise Exit Device

Every exit device has to latch the door somewhere. A rim device latches with a bolt mounted on the face of the door into a strike on the frame. A vertical rod device latches at the top and bottom of the door. A mortise exit device latches through a mortise lock body installed in a pocket cut into the door edge.

That pocket is the point. The latch mechanism sits inside the door, where it's far harder to pry, tamper with or damage than surface-mounted hardware. The result is a cleaner appearance and better resistance to attack, which is why mortise exit devices are a common choice on perimeter doors, main entrances and high-abuse openings in schools and public buildings.

Mortise vs. Rim vs. Vertical Rod

Feature	Mortise	Rim	Vertical rod
Latch location	In a mortise pocket in the door edge	Surface-mounted on the door	Top and bottom of the door
Security	High; latch concealed in the door	Good; latch exposed	Good; two latch points
Door prep	Mortise pocket required	Minimal	Rods surface or concealed
Pairs of doors	With a vertical rod device on the inactive leaf	With a mullion	Without a mullion
Best for	Perimeter and high-security single doors	Simple single doors and mullion pairs	Pairs without a mullion

Sargent Mortise Exit Device Series

Series	Door type	Key point
8900	Wide stile wood and metal doors	4-1/2" minimum stile; concealed single-point guarded latch
8300	Narrow stile doors, including aluminum	1-3/4" minimum stile; hollow stile with at least 1-3/8" square inside
KP8977 / KP8978	Wide stile doors with keypad entry	Standalone, battery-powered keypad mortise exit device
12- prefix	Fire-rated openings	Fire exit hardware versions with no mechanical dogging

Measure the stile first. The stile width decides the series. A wide stile 8900 needs 4-1/2 inches, while narrow aluminum storefront doors call for the 8300.

Available Finishes

Code	Finish	Where it fits
630 / US32D	Satin stainless steel	The standard exit device finish; resists wear and cleaning
629 / US32	Bright stainless steel	Polished stainless entrances
613 / US10B	Oil-rubbed bronze	Bronze and darker hardware schedules
605 / US3	Bright brass	Traditional polished brass entrances
606 / US4	Satin brass	Satin brass hardware schedules
689 / US28	Aluminum painted	Matches aluminum framing and closers
BSP	Black suede powder coat	Contemporary and dark hardware schedules
WSP	White suede powder coat	White frames and light entrances

Sargent 80 Series exit devices are offered in most standard finishes but not in 626/US26D satin chrome, so 630/US32D satin stainless is the usual match where locksets elsewhere are satin chrome. Availability varies by model; confirm on the product page.

Finish codes follow the BHMA system, with the older US designation shown alongside. The two codes describe the same finish, so 630 and US32D are interchangeable on a hardware schedule.
