Sargent 8204 WTF Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8200 Series 8204 WTF Trim Mortise Lockset brings a full-escutcheon architectural presence to storeroom and closet openings that demand both visual refinement and uncompromising access control. The WT Heavy Wrought Escutcheon (2-1/2" wide, surface mounted) paired with the F lever frames the door face with a clean, contemporary profile — a deliberate design choice for institutional and commercial interiors where the hardware is as much a statement as a safeguard. Operating under ANSI F07 Storeroom or Closet function, the 8204 grants entry by key only from the outside while ensuring free egress from the inside at all times, with no deadbolt, no thumbturn, and no electrification — exactly the straightforward, secure credential required for controlled-access ancillary spaces. Built on Sargent's proven 8200 Series lockbody platform, this configuration delivers ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 performance behind a trim that keeps the aesthetic vocabulary precise and modern.

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

The 8204 operates on a single rule: access in, freedom out. A key outside retracts the latchbolt for entry — the outside trim is locked at all times and cannot be turned without a key. Inside, the lever always retracts the latchbolt freely, ensuring unobstructed egress. There is no deadbolt, no thumbturn, and no electrification on this lock.

• Key-Only Outside Entry: The outside lever is locked at all times; only a valid key retracts the latchbolt from the corridor or public side. This eliminates any possibility of unauthorized entry by manipulating the trim alone, making the 8204 the correct function wherever a storeroom or closet must remain secured against casual access.
• Always-Free Inside Egress: The inside lever retracts the latchbolt freely at all times with no credential required. This unconditional inside release satisfies life-safety egress requirements for occupied ancillary spaces without the complexity of a deadbolt or an occupancy indicator.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door closes and the deadlatch plunger is depressed by the strike, it deadlocks the latchbolt against retraction by shimming or carding — a passive, automatic layer of protection that engages every time the door latches.
• Anti-Friction Stainless Steel Latchbolt: The one-piece latchbolt delivers a 3/4" (19mm) throw in stainless steel. The anti-friction feature reduces closing force against a door stop or weatherstrip, which matters in high-traffic service corridors and facilities where positive latching must be consistent across thousands of cycles.

WT Heavy Wrought Escutcheon (2-1/2" wide, surface mounted) and F Lever: Full-Plate Presence with Clean Modern Lines

The WTF trim pairs the WT Heavy Wrought Escutcheon (2-1/2" wide, surface mounted) — a full-height escutcheon plate that covers the lock area and gives the door face a strong, unified architectural look — with the F lever, whose contemporary profile suits the clean geometric language of modern institutional interiors. The this trim is handed; specify LH, RH, LHR, or RHR when ordering.

• WT Heavy Wrought Escutcheon (2-1/2" wide, surface mounted) — Handed Trim: Unlike the lock body, the this trim is handed and must be ordered to match the door swing: LH, RH, LHR, or RHR. Specifying the wrong hand at order entry is the single most common cause of trim rework on escutcheon mortise sets — confirm door swing before submitting.
• F Lever — 30-Degree Actuation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. That reduced arc means less wrist travel and lower operating force, which contributes to compliance with the Americans with Disabilities Act — though the catalog notes to consult local authorities to confirm compliance with jurisdiction-specific requirements.
• Through-Bolted, Interchangeable Mounting: Trim, levers, and escutcheons are through-bolted and fully interchangeable between rose and escutcheon configurations across the 8200 Series. This ensures proper alignment is maintained under repeated use and allows trim substitution without altering the lock case.
• Lever Springs Inside the Case: The lever return springs are contained inside the lock case rather than in the trim assembly. This simplifies trim installation and replacement in the field, since the springs do not need to be managed or re-seated when the escutcheon or lever is changed.

Key Product Features

• ANSI/BHMA A156.13 Series 1000 — Operational and Security Grade 1: Certified to and exceeding the highest grade in the ANSI/BHMA mortise lock standard with standard trims. Note that LFIC and SFIC cylinder options available on this listing do not meet Security Grade 1 requirements — specify LC or LA keyway if Security Grade 1 must be maintained end-to-end.
• 16 Million Cycle Durability: The 8200 Series completed UL above-and-beyond cycle testing at 16 million cycles — 16 times the ANSI/BHMA A156.13 Grade 1 requirement. For a storeroom lock on a busy service corridor, that margin translates directly into a longer service interval before mechanical wear becomes a concern.
• 12-Gauge Zinc-Dichromate Lock Case: The lock case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, at 7/64" (3mm) /.109" wall thickness. The zinc dichromate plate protects the interior steel components against corrosion during installation and throughout the lock's service life.
• Cold Forged Steel Hubs and High Carbon Steel Spring Cartridge: The 8200 Series uses cold forged steel hubs — not sintered iron — paired with a high carbon steel spring cartridge. Catalog page 4 names the materials for both lines without ranking them.
• UL/cUL 3-Hour Fire Rating and Positive Pressure Compliance: UL and cUL Listed for A-label 3-hour fire doors (4x10 single, 8x10 double) and lesser classifications, to both US and Canadian safety standards. 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.
• 10-Year Limited Mechanical Warranty: Sargent backs the lockbody with a 10-year limited mechanical warranty. The 8204 is a purely mechanical lock — it has no electrical or electromechanical components — so the mechanical warranty is the only warranty that applies. Warranty coverage is limited to replacement of the lockbody.

Technical Specifications

Ordering & Installation Information

The 8204 WTF installs to ANSI/SDI A250.14 modified per template 7057 door prep on 1-3/4" (44mm) thick doors standard, with a fixed 2-3/4" (70mm) backset — no backset adjustment is available, so confirm rough-in dimensions before ordering. A 4-1/2" (114mm) minimum stile is required; narrower stiles cannot accommodate the mortise case. The lock body is field reversible without opening the case or removing parts, but the this trim is handed — order must specify LH, RH, LHR, or RHR. Six finishes are offered: 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze, and 625 Polished Chrome. Cylinder and keyway options on this listing: LC (Less Cylinder), LA Keyway, 60 (LFIC Less Core), and 70 (SFIC Less Core) — note that LFIC and SFIC cores do not meet ANSI/BHMA A156.13 Security Grade 1. Two nickel silver keys are included; masterkeying and construction keying are available. The broader 8200 Series also offers MicroShield antimicrobial coating, status indicators, electro-mechanical configurations with ElectroLynx connectors, and security trim options as separately specified configurations.
