Sargent 8204 OE Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8204 OE Trim Mortise Lockset brings the trusted engineering of the Sargent 8200 Series to storeroom and closet openings that demand controlled entry without the bulk of a large escutcheon. The 8204 storeroom/closet function (ANSI F07) is a single-cylinder design: a key outside is the only means of retracting the latchbolt from that side, while the inside lever remains free at all times for immediate egress. Trim code OE pairs a slender O Rose at 2-3/4" diameter with the E lever, covering the minimum of door face and keeping sight lines clean — an advantage on narrow stiles and in interiors where hardware should serve the space rather than dominate it. Certified to ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, this lockset is a factory-order item built to institutional standards.

Single-Cylinder Storeroom/Closet Control — ANSI F07 Function Explained

The 8204 defines a clear access boundary: only a key holder can retract the latchbolt from outside, while occupants on the inside always operate the lever freely. There is no deadbolt, no thumbturn, and no occupancy indicator — the function is purposefully simple, and that simplicity is what makes it reliable for storerooms, supply closets, and similar controlled-access openings.

• Key-Only Outside Entry: The outside trim is locked at all times — only a presented key retracts the latchbolt. Because no inside release affects the outside lever, there is no way for an occupant to inadvertently leave the door unsecured from the corridor side.
• Unrestricted Inside Egress: The inside lever always retracts the latchbolt freely, with no key, no code, and no delay. For any occupant already inside, exit is immediate — a practical and life-safety requirement on any door used for storage or access to supplies.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door closes, it deadlocks the latchbolt against push-back, so the latch cannot be slipped without a key — a meaningful upgrade over a latchbolt operating alone.
• Anti-Friction One-Piece Latch: The stainless steel latchbolt delivers a 3/4" (19 mm) throw with an anti-friction design, so the door closes positively against the strike without requiring the lever to be held or the door to be slammed. This also reduces wear on both the latch face and the strike over the life of the hardware.

O Rose (2-3/4" dia) and E Lever — Compact Footprint, Consistent Operation

At just 2-3/4" in diameter, the O Rose occupies less door face than a full escutcheon, making it the natural choice where stile width is tight or where a clean, understated appearance is the design intent. The E lever works with that compact base to deliver an opening that is straightforward for every user, regardless of hand strength or grip.

• Compact Rose Carrier: The O Rose measures 2-3/4" (diameter) — a minimal footprint that leaves surrounding door face clear and is well-suited to narrow-stile doors requiring the 4-1/2" minimum stile the lockbody demands. Less trim coverage also means fewer surfaces to maintain.
• Low-Force Lever Operation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. That shallow arc reduces the force and range of motion a user must apply, supporting accessibility at the opening. The lever design complies with the American Disability Act — consult local authorities to confirm requirements in your jurisdiction.
• Lever Springs Inside the Case: The lever return springs are contained inside the lock case rather than in the trim assembly. This simplifies trim removal and reinstallation in the field and means the spring mechanism is protected from the environment at the door face.
• Through-Bolted, Interchangeable Trim: To ensure proper alignment, the trim is through-bolted and fully interchangeable between rose and escutcheon configurations. The E lever is non-handed — no handing selection is required when ordering trim — and the same lever works on either face of the door.

Key Product Features

• ANSI/BHMA A156.13 Series 1000, Operational Grade 1 and Security Grade 1: Certified to the highest commercial grade for both operational performance and security with standard trims. This is the specification grade required by most institutional and commercial project specifications.
• 16 Million Cycle Verified Durability: The 8200 Series completed UL cycle testing at 16 million cycles — sixteen times the ANSI/BHMA A156.13 Grade 1 requirement (Verification ID: V584148). For a storeroom lock cycled dozens of times daily, that margin translates directly to a longer service life before maintenance.
• 12-Gauge Zinc-Dichromate Case with Cold Forged Steel Hubs: The lock case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, at 7/64" (3 mm) thickness. The 8200 Series hubs are cold forged steel — not the sintered iron used in the 7800 line — backed by heavy-duty wrought steel hubs and a high-carbon steel spring cartridge.
• UL/cUL 3-Hour Fire Door Listing and Positive Pressure: Listed to US and Canadian safety standards for A label 4×10 single and 8×10 double (3-hour fire door) and lesser-class doors. Also meets ANSI/UL 10C Positive Pressure Fire Test requirements. The armored front is stamped with the letter F and the UL symbol to confirm the listing at inspection.
• Cylinder and Keyway Options: This listing is offered in four cylinder configurations: LC (Less Cylinder) for owner-supplied cylinders; LA Keyway (standard keyway, two nickel silver keys included, masterkeying and construction keying available); 60 — LFIC Less Core; and 70 — SFIC Less Core. Note that LFIC and SFIC cylinder configurations do not meet the ANSI/BHMA A156.13 Security Grade 1 requirement.
• 10-Year Limited Mechanical Warranty and Field-Reversible Lock Body: The lockbody carries a 10-year limited mechanical warranty (warranty limited to replacement of lockbody). The lock body is field reversible — re-handed without removing parts or opening the lock case — reducing installation time and eliminating the need to stock separate handing on the job site.

Technical Specifications

Ordering & Installation Information

The 8204 OE trim lockset requires a door prepared to ANSI/SDI A250.14 modified per template 7057. The backset is 2-3/4" (70 mm) only — no other backset is available for this lockset, so confirm rough prep before ordering. A minimum stile of 4-1/2" (114 mm) is required; doors with narrower stiles cannot accept this lockbody. Standard door thickness is 1-3/4" (44 mm), though the 8200 Series is offered for door thicknesses from 1-3/8" to 6" — specify door thickness when ordering for non-standard applications. The lock body is field reversible without opening the case; the E lever trim is non-handed and requires no handing selection. Choose from six finishes: 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze, or 625 Polished Chrome. Cylinder options are LC, LA, 60 (LFIC less core), or 70 (SFIC less core). The broader 8200 Series offers optional configurations including MicroShield antimicrobial coating, electro-mechanical functions, status indicators, and security trim styles — consult DoorwaysPlus for Series-level options. Lead time: factory order, 3–4 weeks.
