Sargent 8204 LW1B Trim Storeroom or Closet Function Mortise Lockset

Specified to ANSI F07 Storeroom or Closet function, the Sargent 8204 LW1B is a heavy-duty mortise lockset from the Sargent 8200 Series — a line long regarded as the industry benchmark for institutional and commercial mortise hardware. This configuration pairs the LW1 Escutcheon with the B lever to deliver a trim profile that reads cleanly in a hardware schedule and coordinates readily across door types within a project. Entry is by key outside only; the inside lever always retracts the latchbolt freely, supporting unobstructed egress. The 8204 has no deadbolt and no thumbturn. For architects and specifiers building out a hardware schedule around escutcheon-trim mortise locksets, the LW1B offers a well-defined function, a defined cylinder size, and a broad finish selection within a single orderable configuration.

8204 Storeroom or Closet Function — ANSI F07: Key-Controlled Entry with Always-Free Egress

The 8204 ANSI F07 function keeps the outside trim locked at all times — entry requires a key on every approach. Inside, the lever always retracts the latchbolt without a key or auxiliary action, so egress is never impeded. An auxiliary deadlatch and anti-friction stainless steel latch complete the bolt work. There is no deadbolt, no thumbturn, and no electrification on this function.

• Key-Only Outside Entry: The outside trim is locked at all times; a key is required to retract the latchbolt and gain entry on every use. This makes the 8204 appropriate for storerooms, closets, and any space where uncontrolled access must be prevented regardless of time of day or occupancy.
• Always-Free Inside Egress: The inside lever retracts the latchbolt at all times without a key or any unlocking step. Because egress is never contingent on a credential, this function supports life-safety requirements for occupied spaces where the door must always be openable from the secure side.
• Auxiliary Deadlatch: The stainless steel auxiliary deadlatch is non-handed and engages automatically when the door closes. It deadlocks the latchbolt against the strike, preventing the latch from being slipped or pushed back when the door is in the closed position.
• Anti-Friction Stainless Steel Latchbolt: The one-piece latchbolt has a 3/4" (19mm) throw and is built from stainless steel with an anti-friction feature that eases the door into the strike under spring pressure. The multi-function 8200/7800 lockbody that carries this bolt work supports nine functions in a single case, so the same mortise pocket accommodates future function changes.

LW1 Escutcheon with B Lever: Trim Profile for Hardware Schedule Coordination

The LW1B trim combines the LW1 Escutcheon carrier with the B lever design. Specifying a named escutcheon and lever style in a hardware schedule gives the project team a consistent, verifiable trim reference across all 8204 openings. Note that this trim is handed — the correct hand (LH, RH, LHR, or RHR) must be specified at time of order.

• Trim Handing Requirement: The this trim is handed — LH, RH, LHR, or RHR must be declared when ordering. This is distinct from the lock body, which is field reversible without opening the case. Confirm door hand before submitting the order to avoid trim replacement on the job site.
• 30-Degree Lever Rotation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. The reduced arc lowers the operating force applied to the trim and makes the action feel positive and controlled — a characteristic that reads well against lever-operation requirements in a hardware specification.
• Through-Bolted, Interchangeable Trim: To ensure proper alignment, the trim is through-bolted and fully interchangeable between rose and escutcheon configurations within the 8200 Series. Lever springs are contained inside the lock case rather than in the trim, which simplifies trim removal and reinstallation during a finish change or maintenance call.
• ADA Lever Operation and Finishes: The lever design complies with the American Disability Act — consult local authorities to confirm applicability to your jurisdiction. Six architectural finishes 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, supporting finish coordination across a hardware schedule.

Key Product Features

• ANSI/BHMA A156.13 Series 1000, Operational Grade 1 and Security Grade 1: The 8204 LW1B is certified to and exceeds these grades with standard trims. Note that if LFIC (option 60) or SFIC (option 70) cores are installed, the assembly does not meet Security Grade 1 requirements per the catalog.
• 16 Million Cycle Durability: The Sargent 8200 Series completed a UL cycle above-and-beyond test at 16 million cycles — sixteen times the ANSI/BHMA A156.13 Grade 1 cycle requirement (Verification ID: V584148). For high-traffic storeroom or closet openings, that durability margin directly reduces long-term maintenance exposure.
• 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" (3mm) thickness. The 8200 Series hubs are cold forged steel, paired with a high-carbon steel spring cartridge — components that the catalog credits with superior strength and cycle life.
• UL/cUL 3-Hour Fire Rating and UL 10C Positive Pressure: The lockset is UL and cUL Listed for A-label 4×10 single and 8×10 double (3-hour fire door) and lesser class doors. It also meets ANSI/UL 10C Positive Pressure Fire Test of Door Assemblies. The armored front is stamped with the letter F and UL symbol to confirm the listing at the door.
• Cylinder and Keyway Options: Four options are offered on this listing: LC (Less Cylinder) for owner-supplied cylinders; LA Keyway (standard 6-pin brass, #41 size, masterkey and grand masterkey capable); 60 — LFIC Less Core; and 70 — SFIC Less Core. LFIC and SFIC core options do not meet ANSI/BHMA A156.13 Security Grade 1 requirements.
• 10-Year Limited Mechanical Warranty: Sargent backs the 8200 Series lockbody with a 10-year limited mechanical warranty, limited to replacement of the lockbody. The 8204 is a fully mechanical function — there is no electrical or electro-mechanical component in this configuration.

Technical Specifications

Ordering & Installation Information

Door preparation follows ANSI/SDI A250.14 modified per template 7057. The backset is 2-3/4" (70mm) only — no alternative backset is available, so confirm rough frame and door edge conditions before specifying. A 4-1/2" (114mm) minimum stile is required; doors with narrower stiles cannot accept this lockbody. Standard door thickness is 1-3/4" (44mm), though the 8200 Series is available for door thicknesses from 1-3/8" to 6" — consult factory for non-standard thickness. The lock body is field reversible without opening the case, but this trim is handed: specify LH, RH, LHR, or RHR with every order. Six finishes are available: 626, 630, 613E, 605, 612, and 625. Cylinder options are LC, LA, 60 (LFIC less core), and 70 (SFIC less core). The broader 8200 Series also offers MicroShield antimicrobial coating, status indicators, ElectroLynx electro-mechanical configurations, and vandalism-deterrent trim options — all separately specified at the series level. Lead time: 3–4 weeks factory order.
