Sargent 8204 LP Trim Storeroom or Closet Function Mortise Lockset

When a retrofit schedule demands drop-in compatibility with an existing 3-1/2" round rose footprint, the Sargent 8200 Series 8204 LP Trim Mortise Lockset is engineered to meet it. Built on Sargent's century-proven 8200 Series platform, the 8204 Storeroom or Closet function (ANSI F07) delivers key-controlled outside entry with always-free inside egress — the exact operational profile required for storerooms, supply closets, and secured utility spaces. Trim code LP pairs the L Rose (3-1/2" dia) with the P lever, a combination that slots into standard ANSI mortise prep without alteration and coordinates naturally against other LP-trimmed hardware across a project schedule. Certified to ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with standard trims, this lockset is a first-choice specification for architects and facility managers who need proven security with clean, schedulable aesthetics.

8204 Storeroom / Closet Function — ANSI F07 Key-Only Outside Entry

The 8204 ANSI F07 function is purpose-built for spaces that must remain secured from the corridor at all times. There is no deadbolt, no thumbturn, and no occupancy indicator — the lock does exactly what a storeroom requires: key outside for controlled entry, always-free lever inside for unrestricted egress, and a stainless auxiliary deadlatch that keeps the door positively latched the moment it closes.

• Key-Only Outside Entry: The outside trim is locked at all times — only a valid key retracts the latchbolt from the corridor side. Because there is no thumbturn and no inside-release override for the outside trim, access is fully controlled by key possession, which is the defining requirement of a storeroom or closet function.
• Always-Free Inside Egress: The inside lever always retracts the latchbolt, with no key or credential required. This unconditional inside release is critical for life-safety compliance in occupied spaces, ensuring occupants are never trapped regardless of how the outside is secured.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. When the door closes against the strike, the deadlatch plunger engages automatically, preventing the latchbolt from being shimmed or pushed back without a key — a meaningful layer of passive security that requires no action from the user.
• Anti-Friction Latchbolt & Multi-Function Lockbody: The one-piece stainless steel latchbolt offers a 3/4" (19mm) throw with an anti-friction design that reduces door-closing resistance and wear over time. It is housed in Sargent's multi-function lockbody — the same case that supports nine functions.

LP Trim: L Rose (3-1/2" dia) with P Lever

The LP trim combines a 3-1/2" diameter L Rose with the P lever, a pairing chosen by specifiers who need the largest of the standard round roses to match existing ANSI-standard round-rose hardware already on a project. The P lever's geometry returns close to the door face, keeping the trim profile clean and consistent across mixed-use corridors where lever projection must be managed.

• Non-Handed Trim — No Handing Selection Required: The P lever trim is non-handed, meaning a single part number installs on doors of any swing without modification. This eliminates handing errors at the point of order and simplifies field inventory, particularly useful on retrofit projects where door swing may not be confirmed until installation.
• 30-Degree Lever Rotation: Only 30 degrees of lever rotation is required to fully retract the latchbolt. This low-arc operation reduces the force and travel needed to open the door — a practical benefit for high-traffic closets and a key reason the lever design complies with American Disability Act guidelines; consult local authorities regarding requirements in your jurisdiction.
• Through-Bolted, Interchangeable Trim: Per Sargent's specification, trim is through-bolted and fully interchangeable between rose and escutcheon configurations to ensure proper alignment. This means an LP-trimmed lock can be updated to a different rose or escutcheon style in the future without disturbing the mortise case, protecting the hardware investment across building lifecycle changes.
• Lever Springs Inside the Lock Case: The lever return springs are contained inside the lock case rather than in the trim roses, which simplifies trim removal and reinstallation during maintenance without the risk of losing or misaligning external spring components — a detail that reduces service time in facility management environments.

Key Product Features

• 16 Million Cycle Durability — Verified: 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). For a storeroom lock that may see dozens of key operations per day, this durability margin directly translates to reduced replacement and maintenance costs over the building's life.
• ANSI/BHMA A156.13 Series 1000 — Operational Grade 1 & Security Grade 1: Certified with standard trims. Note: LFIC (option 60) and SFIC (option 70) cylinders, while available on this listing, do not meet Security Grade 1 requirements — specify the LC or LA keyway options when Security Grade 1 must be maintained through the cylinder.
• 12-Gauge Heavy-Duty Wrought Steel Case: The lock case is 12-gauge wrought steel, zinc dichromate plated, at 7/64" (3mm) /.109" thickness. The cold-rolled steel inside front further secures the lock body within the door, and the cold forged steel hubs — paired with a high carbon steel spring cartridge — provide the hub and drive strength that supports the 8200 Series' extended cycle life. Cold forged steel hubs are specific to the 8200 line.
• UL/cUL 3-Hour Fire Door Listed & UL 10C Positive Pressure: The 8204 LP is UL and cUL Listed for A-label 4x10 single and 8x10 double (3-hour fire door) and lesser class doors for both US and Canadian safety standards. It 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 status in the field.
• Cylinder & Keyway Options for This Listing: Four options are offered: LC (Less Cylinder — supply your own); LA Keyway (standard Sargent LA keyway, 6-pin, masterkey and grand masterkey capable, construction keying available, two nickel silver keys included); 60 (LFIC Less Core); and 70 (SFIC Less Core). All cylinders on this trim are brass, size #41 (1-1/8"). LFIC and SFIC cores do not meet ANSI/BHMA A156.13 Security Grade 1. Security key systems — Degree, Signature, Keso, Keso F1, and XC — are available through Sargent.
• 10-Year Limited Mechanical Warranty & Field-Reversible Lock Body: The lock body carries a 10-year limited mechanical warranty (limited to replacement of the lockbody). In the field, the lock body is re-handed without removing parts or opening the lock case — a fast, error-reducing process that matters when hardware arrives on-site before door handing is fully confirmed.

Technical Specifications

Ordering & Installation Information

The 8204 LP requires door prep per ANSI/SDI A250.14 modified per template 7057 and a fixed 2-3/4" (70mm) backset — no other backset is available, so confirm rough opening and door edge prep before ordering. A 4-1/2" (114mm) minimum stile is required; doors narrower than this cannot accept the mortise case. Standard door thickness is 1-3/4" (44mm), though the 8200 Series is offered for door thicknesses from 1-3/8" to 6" — consult factory for non-standard thickness configurations. The lock body is field reversible without opening the case; the P lever trim is non-handed and requires no handing selection at order. Six finishes are available: 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). Cylinder options are LC, LA Keyway, 60 (LFIC Less Core), and 70 (SFIC Less Core); LFIC and SFIC cores do not meet Security Grade 1. The 8200 Series also offers MicroShield antimicrobial coating, status indicators, ElectroLynx electro-mechanical configurations, and vandalism-deterrent secure-fastener trim as separately specified series options. Factory lead time: 3–4 weeks.
