Sargent 8204 LNF Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8204 LNF brings the disciplined geometry of a 2" diameter LN rose and a F lever to the workhorse of controlled-access hardware: the storeroom/closet mortise lockset. Part of the proven Sargent 8200 Series, this configuration delivers ANSI F07 storeroom/closet function — outside entry by key only, with the inside lever always free for immediate egress — in a trim profile designed for architects and specifiers who prioritize minimal visual weight on the door face. Where a full escutcheon plate commands the elevation, the compact LN rose steps back, letting the lever read as its own design element. Behind that restrained face sits a mortise lockbody certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, built to perform across institutional, commercial, and high-traffic facilities.

Storeroom/Closet Function — ANSI F07: Controlled Entry, Unrestricted Egress

The 8204 is a single-cylinder, key-outside-only function: the outside trim remains locked at all times and yields only to a valid key, while the inside lever always retracts the latchbolt freely. There is no deadbolt, no thumbturn, and no occupancy indicator — this function is purpose-built for storerooms, supply closets, and secured utility spaces where inside occupants must never be trapped.

• Key-Only Outside Entry: The outside trim is locked at all times; only a valid key retracts the latchbolt. Because there is no thumbturn and no inside control of the outside trim, the secured side remains consistently controlled regardless of occupant action inside.
• Always-Free Inside Egress: The inside lever retracts the latchbolt at all times without a key or any unlocking step. This unconditional egress path is the defining characteristic of ANSI F07 and is essential for life-safety compliance in occupied storage areas.
• Stainless Steel Auxiliary Deadlatch: The non-handed auxiliary deadlatch is stainless steel and works in concert with the latchbolt to resist unlatching from outside. Because it is non-handed, it functions correctly regardless of which way the lock body is oriented in the door.
• Anti-Friction Latchbolt: The one-piece stainless steel latchbolt provides a 3/4" (19mm) throw with an anti-friction design, reducing the force needed to pull a door closed against the strike — a practical benefit on high-traffic service corridors where doors are closed repeatedly throughout the day.

LN Rose (2" Diameter) with F Lever: Refined Proportions, Lasting Performance

The LNF trim pairs a 2" diameter LN rose with the F lever, a combination that keeps the door face open and uncluttered. The compact rose presents a smaller footprint than a full escutcheon plate, allowing the lever's own profile to carry the visual statement. This trim is non-handed, so no handing declaration is required at order.

• Compact LN Rose (2" Diameter): At 2" in diameter, the LN rose is notably smaller in footprint than a full escutcheon plate, creating a cleaner sightline on the door face. The result is a contemporary, pared-back aesthetic well suited to modern institutional and commercial interiors.
• Low-Effort Operation: Only 30 degrees of lever rotation is required to retract the latchbolt. That shallow arc reduces the wrist torque a user must apply — a direct benefit for frequent users and for facilities seeking to comply with accessibility guidelines. The lever complies with the American Disability Act; consult local authorities to confirm applicability for your jurisdiction.
• Lever Springs Inside the Case: The lever return springs are contained inside the lock case rather than mounted on the trim itself. This simplifies trim installation and ensures spring geometry remains correct regardless of which finish trim is mounted — a practical advantage when field-changing trim.
• Through-Bolted and Fully Interchangeable: Trim, including the LN rose and F lever, is through-bolted and fully interchangeable between rose and escutcheon configurations to ensure proper alignment. Available in six finishes: 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze, and 625 Polished Chrome.

Key Product Features

• ANSI/BHMA A156.13 Series 1000 Grade 1 — Operational and Security: Certified to and exceeds both Operational Grade 1 and Security Grade 1 requirements with standard trims. Note: the LFIC (option 60) and SFIC (option 70) cylinder configurations available on this listing do not meet Security Grade 1 requirements; specify LA keyway or Less Cylinder (LC) where Security Grade 1 must be maintained.
• 16 Million Cycle Verified Durability: The 8200 Series completed a UL "above and beyond" cycle test at 16 million cycles — exceeding the ANSI/BHMA A156.13 Grade 1 cycle requirement by 16 times. This verified performance (Verification ID V584148) directly translates to a longer service life in high-use storeroom and closet applications.
• 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) thickness. The 8200 Series hubs are cold forged steel — not the sintered iron used in the 7800 line — contributing to the series' cycle life performance.
• UL/cUL 3-Hour Fire Listed and UL 10C Positive Pressure Tested: Listed to US and Canadian safety standards for A label 3-hour fire door assemblies (4×10 single and 8×10 double), with the armored front stamped with the F designation and UL symbol. Also meets ANSI/UL 10C Positive Pressure Fire Test requirements — critical for smoke-control corridor and stairwell applications.
• Cylinder and Keyway Options: Four options are available on this listing: LC (Less Cylinder) for owner-supplied cylinders; LA Keyway (standard, masterkey and grand masterkey capable, two nickel silver keys included); 60 — LFIC Less Core; and 70 — SFIC Less Core. The cylinder is a brass #41 (1-1/8") standard size. LFIC and SFIC cores do not meet ANSI/BHMA A156.13 Security Grade 1.
• 10-Year Limited Mechanical Warranty and Field-Reversible Lock Body: Sargent backs the 8200 Series lockbody with a 10-year limited mechanical warranty (replacement of lockbody). The lock body is field reversible — re-handed without removing parts or opening the lock case — streamlining installation on projects with mixed door handing.

Technical Specifications

Ordering & Installation Information

The 8204 LNF installs on 1-3/4" (44mm) doors as standard, with the series offered across door thicknesses from 1-3/8" to 6" where required. Door preparation follows ANSI/SDI A250.14 modified per template 7057. The 2-3/4" (70mm) backset is the only backset available — verify the door stile before ordering, as a minimum 4-1/2" (114mm) stile is required to accept the lock body. The lock body is field reversible without opening the lock case; the F lever trim is non-handed and requires no handing selection at order. Specify one of six finishes: 626, 630, 613E, 605, 612, or 625. Cylinder options: LC, LA, 60 (LFIC less core), or 70 (SFIC less core) — note LFIC and SFIC do not meet Security Grade 1. This is a factory order item with a 3–4 week lead time; confirm availability with DoorwaysPlus before specifying on time-sensitive projects. The broader Sargent 8200 Series also offers optional MicroShield antimicrobial coating, electro-mechanical ElectroLynx configurations, status indicators, push/pull ALP trim, and secure vandalism-deterrent fastener options — all available as separately specified configurations.
