PDQ MR117 HJSJ Grade 1 Front Door Function Mortise Lock - Heavy Duty
The PDQ MR117 HJSJ is an architectural-grade, Grade 1 Front Door Function Mortise Lock for high-traffic commercial environments. It pairs the Houston (HJ) lever -- a solid, substantial straight lever -- on a J-Series Sectional (round rose) in a US32D (630) Satin Stainless finish, and is engineered to exceed the rigorous standards of BHMA Series 1000. It suits front doors and apartment corridor doors that need a keyed latch plus a separate deadbolt thrown by key from the outside or a thumbturn from the inside. Its "return-to-door" design is ADA compliant and helps prevent clothing, bags, or straps from snagging on the hardware in busy corridors.
Built to withstand punishing institutional use, the MR Series uses a heavy-duty forged brass and stainless steel internal mechanism and a 1-inch throw investment cast stainless steel deadbolt inside a deep mortise cassette -- providing significantly higher forced-entry protection than standard cylindrical locks, the industry standard for schools, hospitals, and government offices.
ANSI Function F08 or F10: Front Door
The Front Door function operates the latchbolt from either lever with an inside toggle and outside key, and adds a deadbolt controlled by outside key and inside thumbturn:
- Latchbolt operated by lever from either side.
- Toggle locks/unlocks outside lever.
- Key outside retracts latchbolt.
- Key outside extends/retracts deadbolt.
- Thumbturn inside extends/retracts deadbolt.

High-Performance Solutions for Building Security
The PDQ MR Series Mortise Lock addresses the most demanding commercial infrastructure challenges:
- Maximum Forced Entry Resistance: The steel cassette fits deep into the door pocket, providing superior resistance against "kick-in" attacks and physical tampering versus single-point cylindrical locks.
- Positive Deadlocking: The auxiliary deadlatch engages when the door closes, preventing "loiding" or shim attacks against the latch bolt.
- Simplified Key Management: Provided with a Schlage C (SCC) compatible cylinder, the MR117 integrates easily into existing master key systems and supports Interchangeable Core (IC) for rapid re-keying.
- Anti-Sag Lever Technology: The Houston lever is supported by an independent, high-tension spring cartridge that returns the handle to a level horizontal position every time.
- Vandal-Resistant Engineering: The trim features a break-away spindle design; extreme torque or a hammer attack breaks the spindle without compromising the internal locking mechanism.
- Architectural Integration: The Satin Stainless (US32D) base finish offers a clean, professional appearance and excellent corrosion resistance; premium finishes (605, 606, 612, 613E, 622, 629) are also available.
Finish availability: This J-Series lockset is offered in 630 (US32D Satin Stainless) as the base finish, plus premium architectural finishes 605, 606, 612, 613E, 622, 629. It is not offered in 626 (626 is an F-Series finish).
