Sargent 8204 LNJ Trim Storeroom or Closet Function Mortise Lockset

Combining the ergonomic confidence of the J lever with the clean, circular profile of the LN Rose (2" dia), the Sargent 8204 LNJ delivers a storeroom/closet mortise lockset that feels as purposeful in the hand as it is resolute in the frame. Part of the Sargent 8200 Series — the industry benchmark for commercial mortise hardware — the 8204 function (ANSI F07) keeps the outside trim locked at all times, admitting only a valid key, while always allowing free egress from inside. Architects and facility managers specifying secure storage rooms, supply closets, and controlled-access spaces will find in the 8204 LNJ a single-cylinder solution that pairs Grade 1 performance with a lever form substantial enough to inspire confident, low-effort operation shift after shift.

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

The ANSI F07 operating logic is straightforward and uncompromising: the outside trim is locked at all times and yields only to a key, while the inside lever retracts the latchbolt freely without a key or any secondary action. There is no deadbolt, no thumbturn, and no electrification — this is a purely mechanical, single-cylinder storeroom function.

• Key-Only Outside Entry: A key inserted in the outside cylinder retracts the latchbolt for entry; when the key is withdrawn the outside trim returns to the locked state. Because the outside trim is locked at all times, there is no "passage" mode to accidentally leave active — an important detail for controlled-access storage and supply rooms.
• Always-Free Inside Egress: The inside lever retracts the latchbolt at all times without a key or any tool, satisfying life-safety egress requirements and keeping occupants from being trapped. No secondary unlocking step is needed from inside.
• Auxiliary Deadlatch — Stainless Steel, Non-Handed: The stainless steel auxiliary deadlatch depresses when the door closes against the strike, preventing the latchbolt from being retracted by shimming or slipping. Being non-handed, it functions correctly regardless of which way the door swings — an installation convenience that also eliminates a source of field error.
• Anti-Friction Latchbolt — One-Piece Stainless Steel: The one-piece stainless steel latchbolt delivers a 3/4" (19mm) throw with an anti-friction feature that reduces door-closing resistance. The A Multi-Function 8200/7800 Lockbody means this same case supports nine different functions, so the 8204 can be re-specified to a different ANSI function later without replacing the mortise case.

LNJ Trim: LN Rose (2" dia) and J Lever

The LN Rose at 2" diameter presents a refined, compact rose that suits contemporary commercial and institutional interiors without overcrowding the door face. Paired with the J lever — a design with a substantial, secure-feeling grip — the LNJ trim delivers smooth, low-effort operation that begins with only a modest arc of travel.

• 30-Degree Lever Rotation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. That shallow arc means less wrist movement and reduced operating force, which is why this lever suits high-traffic doors and users who benefit from easier handle operation — complies with the American Disability Act; consult local authorities to confirm applicability.
• Non-Handed Trim — No Handing Selection Required: The J lever trim is non-handed, so a single part number works on left-hand or right-hand doors without modification. This simplifies procurement for projects with mixed door swings and eliminates the risk of ordering the wrong hand.
• Through-Bolted, Fully Interchangeable Trim: Trim, levers, and roses are through-bolted and fully interchangeable between rose and escutcheon configurations, ensuring proper alignment and a mechanically sound connection. Lever springs are contained inside the lock case rather than in the trim, making trim removal and reinstallation cleaner and less prone to lost or misaligned components.
• Six Architectural Finishes: The LNJ 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 that covers contemporary, traditional, and institutional palettes.

Key Product Features

• ANSI/BHMA A156.13 Series 1000 — Operational Grade 1 and Security Grade 1: Certified to the highest commercial mortise lock standard with standard trims. Note: LFIC and SFIC cylinder options available on this listing do not meet Security Grade 1 requirements — specify the LA keyway or LC less-cylinder option where Security Grade 1 compliance is required.
• 16 Million Cycle 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 door that may see dozens of entries per day, that margin represents decades of reliable service.
• 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) /.109" thickness. The 8200 Series uses cold forged steel hubs paired with a high carbon steel spring cartridge — cold forged steel is the hub material for the 8200 line specifically.
• UL/cUL Listed — 3-Hour Fire Door and UL 10C Positive Pressure: Listed to US and Canadian safety standards for A-label single 4×10 and double 8×10 doors (3-hour fire rating) and lesser class doors. 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 in the field.
• Cylinder and Keyway Options: Four options are offered on this listing: LC (Less Cylinder) for owner-supplied cylinders; LA Keyway (standard, masterkey- and grand-masterkey-capable, construction keying available); 60 (LFIC Less Core); and 70 (SFIC Less Core). LFIC and SFIC cores do not meet ANSI/BHMA A156.13 Security Grade 1. The standard brass cylinder is size #41 (1-1/8").
• 10-Year Limited Mechanical Warranty: Sargent backs the 8200 Series lockbody with a 10-year limited mechanical warranty. Warranty coverage is limited to replacement of the lockbody.

Technical Specifications

Ordering & Installation Information

The 8204 LNJ requires door preparation to ANSI/SDI A250.14 modified per template 7057 and is standard for 1-3/4" (44mm) thick doors; the 8200 Series is offered across door thicknesses from 1-3/8" to 6" for non-standard applications. The fixed 2-3/4" (70mm) backset is the only backset available — confirm rough prep before ordering. A minimum 4-1/2" (114mm) stile width is required; narrower stiles cannot accept the mortise case. The lock body is field reversible without removing parts or opening the case — re-handing takes place at the job site. The J lever trim is non-handed and requires no handing selection at time of order. Six finishes are available: 626, 630, 613E, 605, 612, and 625. Two nickel-silver keys ship standard; construction keying, masterkeying, and grand masterkeying are available with the LA keyway. The 8200 Series also offers optional MicroShield antimicrobial coating, status indicators, ElectroLynx electro-mechanical configurations, and vandalism-deterrent or security trim options — consult the series catalog for those separately specified configurations. Lead time: 3–4 weeks as a factory order.
