Sargent 8204 OP Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8200 Series 8204 OP Trim Mortise Lockset delivers a precisely engineered Storeroom or Closet function (ANSI F07) for spaces that demand controlled entry with unrestricted egress. Outside, the door is secured at all times — only a key retracts the latchbolt — while inside, the lever always operates freely without a key or any secondary action. Specified here with the O Rose (2-3/4" dia) and P lever trim combination, this lockset pairs a compact, service-friendly rose carrier with a clean lever profile well suited to institutional and commercial interiors. Built on Sargent's patented multi-function lockbody, the 8204 carries ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 certification with standard trims, backed by a 10-year limited mechanical warranty.

8204 Storeroom / Closet Function — ANSI F07: Key-Controlled Entry, Always-Free Egress

The 8204 function is the standard specification for storerooms, supply closets, and similar spaces where only authorized personnel should enter but anyone inside must be able to leave immediately. The outside trim is locked at all times; no push button, no thumbturn, no occupancy indicator — entry requires a key, every time. The 8204 has no deadbolt and no thumbturn.

• Key-Only Outside Entry: Turning a key in the outside cylinder is the sole means of retracting the latchbolt from the corridor side — the outside lever is locked at all times. Because there is no push-button holdback on this function, the door returns to the secured condition the moment it closes, with no chance of the outside accidentally being left unlocked.
• Always-Free Inside Egress: The inside lever retracts the latchbolt at all times without a key or any secondary action. This unconditional egress path is critical for code compliance on occupied storerooms and means occupants are never trapped by a locked condition.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door is fully closed and the deadlatch is depressed by the strike, it guards against latchbolt manipulation — a key reason mortise locks remain the preferred specification over cylindrical locks in higher-security commercial applications.
• Anti-Friction Stainless Latchbolt on a Multi-Function Body: The one-piece, 3/4" (19mm) throw stainless steel latch incorporates an anti-friction feature that reduces closing force and wear over time. The lockbody itself is Sargent's patented multi-function design — the same case supports nine ANSI functions, so replacement bodies and upgrade paths remain available for the life of the opening.

O Rose (2-3/4" dia) and P Lever: Service-Ready Trim for Long-Term Installations

The OP trim combination pairs a 2-3/4" diameter O Rose carrier with the P lever design. The compact round rose keeps the trim footprint tidy on standard stile widths while leaving fastener access straightforward at service — a practical advantage in storeroom applications where hardware adjustments or cylinder rekeying may occur over long building lifecycles. The P lever is non-handed, simplifying stocking and replacement.

• Non-Handed P Lever: The P lever is non-handed, meaning a single trim assembly installs on either hand of door without modification. Combined with the field-reversible lock body, this reduces the number of distinct parts that need to be stocked for multi-door projects or future replacements.
• 30-Degree Lever Return: Only 30 degrees of lever rotation is required to fully retract the latchbolt. This low-rotation geometry reduces the wrist torque a user must apply, which is why the lever trim complies with the Americans with Disabilities Act — consult local authorities to confirm applicability to your specific jurisdiction and installation.
• Lever Springs Inside the Case: The lever return springs are contained inside the lock case rather than in the trim assembly. Because the springs are not disturbed when the rose and lever are removed, field cylinder changes or trim swaps do not risk losing or misaligning spring components — a meaningful serviceability advantage over designs where springs live in the trim.
• Through-Bolted, Interchangeable Trim: Trim, knobs, and levers are through-bolted and fully interchangeable between rose and escutcheon configurations to ensure proper alignment. Six finish options are offered on this listing — 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze, and 625 Polished Chrome — allowing coordination with the surrounding architectural hardware package.

Key Product Features

• 16 Million Cycle Verified Durability: The Sargent 8200 Series completed a UL "above and beyond" cycle test at 16 million cycles (Verification ID: V584148), exceeding the ANSI/BHMA A156.13 Grade 1 cycle requirement by 16 times. For a storeroom lock that may be keyed dozens of times per day, this verified longevity translates directly to reduced maintenance budgets.
• ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1: Certified with standard trims. Note that LFIC and SFIC cylinder options, which are offered on this listing, do not meet Security Grade 1 requirements — specify conventional cylinder options (LC or LA keyway) where Security Grade 1 must be maintained throughout.
• 12-Gauge Zinc Dichromate Steel Case: The lockbody case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, at 7/64" (3mm) /.109" wall thickness, with cold forged steel hubs and a high-carbon steel spring cartridge providing the structural foundation for the verified cycle life.
• UL/cUL 3-Hour Fire Rated and UL 10C Positive Pressure Listed: Listed to US and Canadian safety standards for A-label 4x10 single and 8x10 double (3-hour fire door) and lesser-class doors. The lock also meets ANSI/UL 10C Positive Pressure Fire Test requirements. The armored front is stamped with the letter F and UL symbol to confirm listing at the door.
• Cylinder and Keyway Options: Four options are available on this listing: LC (Less Cylinder) for owner-supplied cylinders; LA Keyway standard conventional cylinder (ANSI/BHMA A156.5 Grade 1, 6-pin, nickel silver keys included); 60 — LFIC Less Core; and 70 — SFIC Less Core. LFIC and SFIC cores do not meet ANSI/BHMA A156.13 Security Grade 1 requirements. The standard cylinder size for this trim is #41 (1-1/8") brass. The LA keyway can be masterkeyed, grand masterkeyed, or construction keyed.
• 10-Year Limited Mechanical Warranty: Sargent's 10-year limited mechanical warranty covers the lock body, providing long-term assurance for institutional and commercial facilities with extended asset lifecycles.

The standard door thickness is 1-3/4" (44mm); the 8200 Series is offered for doors from 1-3/8" to 6" thick when specified with the appropriate case option. The lock body is field reversible without removing parts or opening the case; the P lever trim is non-handed and requires no handing selection at order. Six architectural finishes are available: 626, 630, 613E, 605, 612, and 625. Cylinder options on this listing are LC, LA, 60 (LFIC less core), and 70 (SFIC less core). Factory lead time is 3–4 weeks. The broader Sargent 8200 Series also offers optional MicroShield antimicrobial finish coating, electro-mechanical configurations with ElectroLynx connectors, status indicators, push/pull ALP trim, and secure or vandalism-deterrent fastener options — consult DoorwaysPlus for series-level configurations.
