What the BJSJ Code Means

If you searched "bjsj" and landed here, that's a PDQ trim option code. In PDQ's ordering system, the letters identify the lever design, trim series, and finish combination. B is the Boston lever one of PDQ's 10 standard lever styles. J identifies the J series escutcheon. The last two characters designate the specific finish configuration. PDQ's J series finishes include 605 (Bright Brass), 606 (Satin Brass), 612 (Satin Bronze), 613 (Oil Rubbed Bronze), 629 (Bright Stainless), and 630 (Satin Stainless). If you're ordering from a hardware schedule or spec sheet that shows "BJSJ", you're getting the Boston lever with J series escutcheon in a specific stainless finish confirm the finish code with American Locksets before ordering if the spec sheet isn't clear.

MR115 Storeroom Function at the Door

The MR115 function is storeroom. Outside lever is always rigid turning it without a key does nothing. A key in the outside cylinder retracts the latch for entry. Inside lever is always free, so anyone inside can exit at any time without a key. The auxiliary latch deadlocks the latchbolt the moment the door closes into the frame, so the latch can't be pushed back without a key.

This is the right function for server rooms, pharmacy corridors, equipment storage, supply closets, and any space where unrestricted public access isn't acceptable but egress always has to be available.

J Series Escutcheon and the JW Wide Option

The J in MR115J is the trim series. J is PDQ's standard J series escutcheon sectional trim that mounts through the door in the standard configuration. The JW (J Wide) escutcheon is the retrofit variant. It has a larger face plate that covers the previous fastener holes left behind when you're replacing a different brand of mortise lock Schlage, Best, or Corbin Russwin hardware all leave specific hole patterns. If you're doing a retrofit and the existing holes would show with standard J trim, specify JW. The JW trim also complies with Unified Facilities Guide Specification 08 71 00 for federal projects.

Cycle Test, Materials, and Certifications

PDQ's MR series lockcase is 12-gauge cold-rolled steel. The cycle test result is the main competitive claim: PDQ exceeded BHMA standards by over 11 times more than 11 million cycles. The lock is protected under US Patent 5,813,255 for its innovative reduced-part count design, which also makes it field reversible. You can change handing on-site without sending the lock back to the factory (the MR115 is field reversible; some other MR functions are not confirm before installation).

Cylinder compatibility is wide. The standard cylinder is 6 or 7-pin brass with Schlage C keyway. Large format interchangeable cores compatible with Schlage LFIC also work. The cylinder is also compatible with Best, Falcon, and Arrow cores, making this lock suitable for facilities running any of those key systems.
