Sargent 8204 LSE Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8204 LSE brings the considered presence of a full-plate escutcheon to storeroom and closet openings that demand both architectural coherence and reliable controlled access. Part of the proven Sargent 8200 Series, this mortise lockset pairs the LS Security Escutcheon with the E lever to create a trim assembly that makes a deliberate statement at the door face — one suited to institutional corridors, commercial facilities and any project where the opening is as visible as it is functional. The 8204 Storeroom/Closet function (ANSI F07) delivers key-controlled outside entry with always-free inside egress: the lock keeps the outside trim secured at all times while occupants exit freely by lever from within. Every component is built to ANSI/BHMA A156.13 Series 1000 Grade 1 standards, ensuring the lock performs as confidently as it looks.

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

The 8204 is a single-cylinder storeroom and closet function: the outside trim is locked at all times, and only a key retracts the latchbolt from outside. Inside, the lever always retracts the latchbolt freely — no key, no credential, no delay. The 8204 has no deadbolt, no thumbturn and no occupancy indicator. Its job is straightforward controlled access, executed with hardware-grade precision.

• Key-Only Outside Entry: Turning a key in the outside cylinder is the sole means of retracting the latchbolt from the corridor side — the outside trim does not turn in the locked state. This makes the 8204 appropriate wherever a room must remain secured against casual entry while staff carry keyed access.
• Always-Free Inside Egress: The inside lever always retracts the latchbolt, with no key or special action required. Because egress is never impeded, the 8204 supports life-safety requirements for occupied spaces where unobstructed exit is essential.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door closes and the latchbolt seats in the strike, the deadlatch automatically deadlocks the latch against the strike, preventing the latchbolt from being shimmed or pushed back without key operation.
• Anti-Friction Stainless Steel Latchbolt & Multi-Function Lockbody: The one-piece stainless steel latchbolt has a 3/4" (19mm) throw with an anti-friction feature that reduces closing resistance against the strike — important on high-traffic doors. The lockbody is Sargent's A Multi-Function 8200/7800 design, meaning the same case can be configured across multiple functions, supporting facility standardisation on a single lockbody platform.

LS Security Escutcheon with E Lever: Full-Plate Trim Designed for Controlled Openings

The LSE trim combines the LS Security Escutcheon — a full escutcheon plate that covers the lock area of the door face — with the E lever. Where a rose-mounted trim exposes the door stile around the cylinder, the LS escutcheon spans that zone with a continuous plate, giving the opening a more resolved, architectural finish appropriate to institutional and commercial corridors.

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.

• LS Security Escutcheon: The LS is a security escutcheon that covers the lock area of the door face. Because it is a full escutcheon and not a rose, it presents a larger, more formal plate profile — a deliberate architectural choice as much as a functional one.
• E Lever and 30-Degree Operation: The E lever requires only 30 degrees of rotation to fully retract the latchbolt. That reduced arc means less wrist effort for every user — a practical benefit on doors that see continuous daily traffic, and one that supports compliance with the Americans with Disabilities Act; consult local authorities to confirm applicability for your jurisdiction.
• Through-Bolted, Fully Interchangeable Trim: To ensure proper alignment, trim is through-bolted, and levers are fully interchangeable between rose and escutcheon configurations across the 8200 Series. Lever springs are contained inside the lock case rather than in the trim, which simplifies trim removal and re-installation without disturbing the spring mechanism.
• Handing — Trim Must Be Specified: This trim is handed. Unlike the lock body, it cannot be reversed in the field — specify LH, RH, LHR or RHR at the time of order. Failing to specify handing is the most common cause of trim mis-shipment on escutcheon-style mortise locksets, so confirm door swing direction before submitting the order.

Key Product Features

• 16 Million Cycle Durability — Verified: The Sargent 8200 Series completed UL cycle testing at 16 million cycles (Verification ID: V584148), exceeding ANSI/BHMA A156.13 Grade 1 cycle requirements by 16 times. For facility managers specifying locks on high-traffic doors, this is the most direct measure of long-term mechanical reliability available.
• ANSI/BHMA A156.13 Series 1000 — Operational and Security Grade 1: The 8204 LSE is certified to and exceeds ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with standard trims — the highest classification under that standard.
• 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, and heavy-duty wrought steel hubs with a high carbon steel spring cartridge contribute to the cycle life and operating strength of the lockbody.
• UL/cUL 3-Hour Fire Door Listed and UL 10C Positive Pressure: The 8204 is UL and cUL Listed for A label 4×10 single and 8×10 double (3-hour fire door) and lesser class doors, and meets ANSI/UL 10C Positive Pressure Fire Test requirements. The armored front is stamped with the letter F and UL symbol to confirm listing at the door.
• Cylinder and Keyway Options for This Listing: This listing is offered with LC (Less Cylinder) or LA keyway conventional cylinders — brass, size #41 (1-1/8"). The LA keyway supports masterkeying and grand masterkeying; construction keying is available. Important: interchangeable core options (LFIC and SFIC) are not available on this trim configuration — specifiers standardising on an IC platform must select a different trim. Two nickel silver keys are included with a keyed cylinder.
• 10-Year Limited Mechanical Warranty: Sargent backs the 8200 Series lockbody with a 10-year limited mechanical warranty (warranty limited to replacement of the lockbody), reflecting the manufacturer's confidence in the components and construction behind the Grade 1 rating.

Technical Specifications

Ordering & Installation Information

The 8204 LSE installs to ANSI/SDI A250.14 modified per template 7057 door prep on doors 1-3/4" (44mm) thick standard, with a fixed 2-3/4" (70mm) backset — no alternative backset is offered, so verify door prep before ordering. A 4-1/2" (114mm) minimum stile is required; narrower stiles cannot accommodate the mortise case. The lock body is field reversible and can be re-handed without opening the case or removing parts, but this trim is handed and must be ordered as LH, RH, LHR or RHR — specify door swing at time of order. Available finishes are 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze and 625 Polished Chrome. Cylinder options on this listing are LC (Less Cylinder) and LA keyway conventional cylinders only. The broader Sargent 8200 Series offers optional MicroShield® antimicrobial coating, status indicators, ElectroLynx® electro-mechanical functions and vandalism-deterrent trim with secure fasteners — consult the series for those configurations. Lead time: factory order, 3–4 weeks.
