Sargent 8204 LSL Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8204 LSL brings together the proven engineering of the Sargent 8200 Series mortise platform and a purpose-built trim package suited to storerooms, supply closets, and secured service spaces throughout institutional and commercial facilities. The 8204 Storeroom or Closet function (ANSI F07) delivers key-controlled outside entry with always-free inside egress — no codes, no credentials required to exit. Trim code LSL pairs the LS Security Escutcheon with the clean, straight-profile L lever, placing a full security escutcheon plate over the mortise preparation in the door face while maintaining a spare, linear aesthetic consistent with contemporary architectural interiors. This is a purely mechanical, single-cylinder lockset: key outside only, with no deadbolt, no thumbturn, and no electrification.

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

Designed specifically for spaces that must remain secured from the corridor side at all times, the 8204 (ANSI F07) keeps the outside trim locked continuously — no passage mode, no holdback. Inside, the lever always retracts the latchbolt freely, satisfying life-safety egress requirements without any additional hardware or credential.

• Key-Only Outside Entry: A key inserted in the outside cylinder retracts the latchbolt; the outside trim is locked at all times and cannot be turned without the key. This enforces continuous perimeter control on storerooms and service closets without relying on staff to re-secure the door after each entry.
• Always-Free Inside Egress: The inside lever retracts the latchbolt at all times regardless of the outside locked condition. Occupants can exit without a key, credential, or any secondary action — a critical life-safety requirement for occupied or potentially occupied spaces.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door closes, it deadlocks the latchbolt against push-in attack, preventing the latch from being depressed from the outside without the correct key.
• Anti-Friction Latchbolt and Multi-Function Lockbody: The one-piece stainless steel latchbolt carries a 3/4" (19mm) throw with an anti-friction design for smooth, consistent latching across high-traffic cycles. The lockbody is a Sargent Multi-Function 8200 unit — the same case supports nine distinct functions, so the hardware platform is consistent across a project even where door functions vary.

LS Security Escutcheon with L Lever — Plate Coverage and Linear Profile

Trim code LSL positions a full LS Security Escutcheon across the lock area of the door face, covering the mortise preparation with a security escutcheon plate. The L lever adds a straight, unornamented linear profile that reads cleanly against both contemporary and transitional architectural interiors — functional and unobtrusive in equal measure.

• LS Security Escutcheon: The LS is a security escutcheon that covers the lock area of the door face. Note that this listing uses the LS security escutcheon — it does not feature the freewheeling outside lever behavior associated with the separate FE trim.
• 30-Degree Lever Rotation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. In practice this means the inside lever responds with a short, light arc — reducing effort for occupants who may be carrying loads, and easing compliance with accessibility requirements. The L lever complies with the Americans with Disabilities Act; consult local authorities to confirm applicability to your jurisdiction and occupancy.
• Through-Bolted, Interchangeable Trim: Trim, knobs, and levers are 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, simplifying installation and trim replacement.
• Finish Options: The LSL trim is available in six architectural finishes: 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) — spanning the principal metal tones used in commercial and institutional specification.

Key Product Features

• 16 Million Cycle Verified Durability: The Sargent 8200 Series completed UL cycle testing at 16 million cycles — exceeding the ANSI/BHMA A156.13 Grade 1 cycle requirement by 16 times (Verification ID: V584148). This is the endurance foundation that makes the 8200 a defensible specification on high-traffic institutional doors.
• ANSI/BHMA A156.13 Series 1000 — Operational Grade 1 and Security Grade 1: Certified to and exceeding both Operational Grade 1 and Security Grade 1 with standard trims. The 8204 LSL carries no IC core option; it is offered with conventional cylinders only (LC or LA keyway), which preserves full Security Grade 1 standing — IC cylinders do not meet Security Grade 1 requirements.
• 12-Gauge Zinc Dichromate Steel Case: The lock case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, at 7/64" (3mm) /.109" thickness. Cold forged steel hubs and a high-carbon steel spring cartridge are specified for the 8200 lockbody, supporting the cycle life and mechanical integrity the Grade 1 rating requires.
• UL/cUL 3-Hour Fire Door Listed and UL 10C Positive Pressure: Listed to US and Canadian safety standards for A-label single 4 x 10 and double 8 x 10 (3-hour fire door) and lesser-class assemblies; the armored front is stamped with the F designation and UL symbol. The lockset also meets ANSI/UL 10C Positive Pressure Fire Test requirements.
• Cylinder and Keyway Options for This Listing: Two ordering paths: LC (Less Cylinder) for owner-supplied or existing-system cylinders, and LA standard keyway with a brass #41 (1-1/8") conventional cylinder — masterkeyed or grand masterkeyed as required, with construction keying available. LFIC and SFIC interchangeable core options are not available on this trim; specifiers standardizing on IC cores must select a different trim configuration.
• 10-Year Limited Mechanical Warranty: Sargent covers the lockbody with a 10-year limited mechanical warranty (replacement of lockbody). Two nickel silver keys are included; control or emergency keys must be ordered separately when required.

Technical Specifications

Ordering & Installation Information

The 8204 LSL installs to ANSI/SDI A250.14 modified per template 7057 door preparation on doors 1-3/4" (44mm) thick standard, with a fixed 2-3/4" (70mm) backset — no backset adjustment is available, so verify rough prep before ordering. A minimum stile width of 4-1/2" (114mm) is required; narrower stiles cannot accommodate the mortise case. The lock body is field reversible and can be re-handed without opening the lock case, which simplifies on-site adjustments. However, this trim is handed and must be specified at the time of order — indicate LH, RH, LHR, or RHR. Six finishes are available: 626, 630, 613E, 605, 612, and 625. Cylinder options on this listing are LC (Less Cylinder) or LA keyway conventional cylinder only; no interchangeable core is offered on this trim. Lead time is 3–4 weeks as a factory order. The broader Sargent 8200 Series offers optional MicroShield antimicrobial finish coating, status indicators, ElectroLynx electro-mechanical functions, and push/pull ALP trim — consult DoorwaysPlus for separately specified configurations.

The catalog states the security benefit directly: Cylinder is protected by the Escutcheon, and (4) Spanner security screws are exposed on inside trim standard. That pairing is the reason to specify LS — the cylinder sits behind the escutcheon plate rather than standing proud of a rose, and the fasteners left exposed on the inside take a spanner bit rather than a common driver.
