Hager 4501M Mortise Lock Exit Device — Grade 1, 36-Inch, Non-Rated
The Hager 4501M is a heavy-duty mortise lock exit device from the Hager 4500 Series, engineered for demanding commercial single-door openings up to 36 inches wide. Combining the high-security deadlocking latch of a full mortise lock body with the hands-free egress of a push-bar panic device, the 4501M meets ANSI/BHMA A156.3 Grade 1 requirements — the highest commercial performance rating for exit hardware. As a Non-Rated (panic) device, it is designed for non-fire-rated single openings where maximum latch security and code-compliant egress are required together. Architects and specifiers looking for a mortise panic exit device with electrified options will also find the 4500 Series supports a full range of electrical prefixes including motorized latch retraction, request-to-exit, latchbolt monitoring, delayed egress, and authorized ingress — making it a strong fit for frame actuator controlled mortise exit device applications.
Grade 1 Features & Benefits
- Mortise Lock Security: The mortise lock case is installed within the door edge, providing superior resistance to forced entry compared to rim or deadlatch configurations — ideal for main entrances and controlled-access openings.
- Deadlocking Latchbolt: The anti-pick, deadlocking latch prevents latch manipulation from the exterior, a key requirement on high-traffic institutional and commercial doors.
- Field-Reversible Handing: The device can be configured for left-hand or right-hand doors in the field without special parts, reducing installation lead time and inventory complexity.
- Hex Key Dogging: Non-fire-rated construction allows hex key dogging so the latchbolt can be held retracted for push/pull traffic flow during business hours — a standard feature on non-rated devices.
- Broad Exterior Trim Compatibility: The mortise case accepts keyed levers, cylinder pulls, and thumbturns, supporting controlled entry while always providing free egress from the push side.
- Wide Electrification Menu: The 4500 Series supports electrical prefixes including RX (request-to-exit), LM (latchbolt monitoring), AI (authorized ingress), DE (delayed egress), OBDE (onboard delayed egress), and MLR (motorized latch retraction) — supporting integrated access control without a separate electric strike.
- Multiple Finish Options: Available in six BHMA finishes including 626 Satin Chrome, 630 Satin Stainless, 613 Oil Rubbed Bronze, 605 Polished Brass, 606 Satin Brass, and 625 Polished Chrome, accommodating a wide range of architectural specifications.
Applications
- Commercial single doors requiring a high-security mortise latch combined with panic egress
- Main entrances and controlled-access openings with exterior keyed trim
- Institutional, education, office, healthcare, and retail openings
- Openings requiring access control integration via electrified mortise exit device options
