Sargent 8204 LF Trim Storeroom or Closet Function Mortise Lockset

Retrofit schedules and new construction alike call for a trim profile that coordinates with existing hardware families without demanding a full rose changeout. The Sargent 8200 Series 8204 LF Storeroom or Closet Mortise Lockset answers that need with the L Rose (3-1/2" dia) and F lever — a clean, round-rose silhouette sized to drop into a broad range of standard mortise preparations. Function 8204 (ANSI F07) delivers controlled single-cylinder entry with unconditional inside egress: key outside, always-free inside trim, and an auxiliary deadlatch that prevents latchbolt manipulation. Certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and tested to 16 million cycles, this is a specification-grade lockset built for the institutional and commercial applications where storeroom security and reliable egress are both non-negotiable.

8204 Storeroom/Closet Function — ANSI F07 Single-Cylinder Control

The 8204 (ANSI F07) function keeps the outside trim locked at all times — entry requires a key, every time. Inside, the trim always retracts the latchbolt freely, ensuring unrestricted egress with no credential required. There is no deadbolt, no thumbturn, and no occupancy indicator on this function; the security model is straightforward controlled access from one side only.

• Key-Only Outside Entry: The outside lever is locked at all times and retracts the latchbolt only when a valid key is used. Because there is no thumbturn or inside unlocking mechanism, there is no way to leave the outside trim in an unlocked condition — the door returns to secured status the moment it closes.
• Unconditional Inside Egress: The inside trim always retracts the latchbolt regardless of the outside locked state. No credential, no tool, and no mode change is needed to exit — a requirement in most occupancies where the space is occupied and egress must never be impeded.
• Stainless Steel Auxiliary Deadlatch: A stainless steel auxiliary deadlatch travels alongside the primary latchbolt. When the door is fully closed and the latchbolt seats in the strike, the deadlatch is depressed by the strike plate, preventing the latchbolt from being slipped or pushed back without key operation. The catalog confirms it is non-handed, so it functions correctly regardless of which way the lock body is oriented.
• Multi-Function Lockbody: The 8204 is built on Sargent's multi-function 8200/7800 lockbody — the same case that supports nine functions in one platform. For a facility manager coordinating multiple openings, this means the physical lock case itself is a common-inventory component; only the cylinder and trim change between functions, simplifying parts stocking and service.

LF Trim — L Rose (3-1/2" Dia) with F Lever

The LF trim pairs the round L Rose at 3-1/2" diameter with the F lever for a contemporary, uncluttered aesthetic that coordinates naturally with modern institutional interiors. The F lever is non-handed, which eliminates a trim handing decision at the time of order and simplifies inventory for projects with mixed swing directions.

• Round Rose Profile: The 3-1/2" diameter L Rose presents a broad, symmetrical footprint on the door face. Its proportions suit both new installations and retrofits where a similarly sized rose is already specified across the opening schedule, maintaining visual consistency without requiring other hardware changes.
• 30-Degree Lever Rotation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. This low operating arc reduces the effort and wrist rotation a user must apply, which is directly relevant to lever compliance — the lever design complies with the American Disability Act; consult local authorities to confirm applicability under your jurisdiction.
• Through-Bolted and Interchangeable Trim: Per Sargent's specification, trim is through-bolted and fully interchangeable between rose and escutcheon configurations to ensure proper alignment. Lever springs are contained inside the lock case rather than in the trim, so trim removal and reinstallation during service or finish changes does not disturb the spring mechanism.
• Six Architectural Finishes: The LF trim is offered in 626 (US26D Satin Chrome), 630 (US32D Satin Stainless), 613E (US10BE Oil Rubbed Bronze Equal), 605 (US3 Polished Brass), 612 (US10 Satin Bronze), and 625 (US26 Polished Chrome) — a range spanning warm bronze tones through cool chrome and stainless, enabling coordination with virtually any architectural hardware schedule.

Key Product Features

• ANSI/BHMA A156.13 Series 1000 — Operational and Security Grade 1: Certified to the highest ANSI/BHMA mortise lock grade for both operational performance and security with standard trims. Note that LFIC and SFIC cylinder options, while available on this listing, do not meet Security Grade 1 requirements — specifiers requiring Security Grade 1 should select the LC or LA keyway options.
• 16 Million Cycle Tested: The 8200 Series completed Sargent's UL above-and-beyond cycle test at 16 million cycles — 16 times the ANSI/BHMA A156.13 Grade 1 minimum requirement (Verification ID: V584148). For a storeroom or supply-room door seeing dozens of operations daily, this margin translates directly to reduced maintenance intervals.
• 12-Gauge Zinc-Dichromate Steel Case with Cold Forged Steel Hubs: The lock case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, at 7/64" (3mm) wall thickness. Hubs on the 8200 Series are cold forged steel — not the sintered iron used in the 7800 line — contributing to the superior strength and cycle life the catalog attributes to the 8200 hub-and-spring cartridge combination.
• UL/cUL Fire Listed and UL 10C Positive Pressure Rated: Listed to US and Canadian safety standards for A-label single (4×10) and double (8×10) 3-hour fire doors and lesser classifications; the armored front is stamped with the letter F and UL symbol to confirm listing. The lock also meets ANSI/UL 10C Positive Pressure Fire Test requirements — a qualification now required by many authorities having jurisdiction for fire-rated openings.
• Field-Reversible Lock Body: The lock case is re-handed without removing any parts or opening the case — a practical advantage on projects where door swing direction is confirmed late in the schedule or changes during installation, eliminating the need to return or re-order the lock body.
• 10-Year Limited Mechanical Warranty: Sargent's 10-year limited mechanical warranty covers the lock body, reflecting the manufacturer's confidence in the 8200 Series' construction. Two nickel silver keys are included; a control key or emergency key must be ordered separately when required.

Technical Specifications

Ordering & Installation Information

The 8204 LF mounts to a standard mortise prep per ANSI/SDI A250.14 modified per template 7057. Backset is 2-3/4" (70mm) only — no alternate backset is available, so verify the door edge-to-centerline dimension before ordering. A 4-1/2" (114mm) minimum stile is required; doors with narrower stiles cannot accept this lock body. The standard door thickness is 1-3/4" (44mm); the 8200 Series is offered for doors ranging from 1-3/8" to 6" thick, with extended spindles and accessories available separately. The lock body is field reversible without opening the case; the F lever trim is non-handed and requires no handing selection at order. Cylinder options on this listing are: LC (Less Cylinder), LA Keyway, 60 — LFIC Less Core, and 70 — SFIC Less Core; note that LFIC and SFIC options do not meet ANSI/BHMA A156.13 Security Grade 1. Six finishes are available as listed above. The 8200 Series also offers MicroShield antimicrobial coating, status indicators, and electro-mechanical configurations as separately specified options. Factory lead time: 3–4 weeks.
