Sargent 8204 LL Trim Storeroom or Closet Function Mortise Lockset

Straight lines, quiet authority, and a lever that responds with just a turn of the wrist — the Sargent 8200 Series 8204 LL Trim Mortise Lockset brings that combination to storeroom and closet doors demanding both reliable access control and effortless interior egress. Governed by ANSI F07 Storeroom or Closet function, this fully mechanical lockset keeps the outside lever locked at all times, admitting only those presenting a key, while the inside lever always retracts the latchbolt freely. The LL trim pairing — an L Rose at 3-1/2" diameter carrying an L lever — gives the door face a clean, linear profile well suited to commercial, institutional, and healthcare interiors. Certified to ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with standard trims, this is a factory-order item with a lead time of 3–4 weeks.

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

The 8204 defines a clear security boundary: the outside trim is locked at all times and yields only to a key, while the inside lever remains always operational so occupants can exit without delay. A stainless steel auxiliary deadlatch and an anti-friction latch work together to keep the door positively latched and resistant to unintended retraction. This is a single-cylinder, fully mechanical function — there is no deadbolt, no thumbturn, no occupancy indicator, and no electrification.

• Key-Only Outside Entry: The outside lever is locked at all times; only a key retracts the latchbolt. Because the outside trim never turns freely, there is no handle-force path an unauthorized person can exploit — entry is gated entirely by cylinder operation.
• Always-Free Inside Egress: The inside lever always retracts the latchbolt with no unlocking step required. This unconditional egress behavior is why the 8204 is the standard choice for storerooms and closets where occupants must be able to leave at any moment.
• Stainless Steel Auxiliary Deadlatch: The auxiliary deadlatch is stainless steel and non-handed. It guards against latchbolt depression — preventing the door from being pushed open by shimming or credit-carding the latchbolt — and it installs correctly regardless of which face of the door it ends up on.
• Anti-Friction One-Piece Latchbolt: The latchbolt is a one-piece stainless steel unit with a 3/4" (19mm) throw and an anti-friction feature that reduces the force needed to pull the door shut against the strike. The multi-function 8200/7800 lockbody underlying this configuration supports nine functions in a single case, so the same lock body can be respecified to a different function in the field without replacing the case.

LL Trim: L Rose (3-1/2" dia) and L Lever — A Clean Linear Profile

The L lever's straight, unadorned profile reads as contemporary and institutional in equal measure, pairing naturally with the round 3-1/2" diameter L Rose to produce a door face that doesn't compete with surrounding architecture. Only a 30-degree lever rotation is required to fully retract the latchbolt, so the door opens with minimal wrist travel — a practical advantage on a heavily trafficked closet or storeroom door throughout a full shift.

• 30-Degree Lever Rotation: Just 30 degrees of arc fully retracts the latchbolt. That shallow sweep means less wrist deviation per cycle and easier one-handed operation under load — relevant on doors where staff routinely carry items in one hand.
• Non-Handed Trim: The L lever trim is non-handed, so no handing selection is required when ordering this LL configuration. The lock body is separately field-reversible without opening the case, keeping last-minute door swing changes on the job site from becoming a hardware delay.
• Through-Bolted and Interchangeable: Trim — rose and lever — is through-bolted and fully interchangeable between rose and escutcheon configurations. This ensures proper lever-to-latch alignment and allows the same lever style to be carried across rose and escutcheon trims elsewhere in a project for visual consistency.
• Lever Springs Inside the Case and ADA Lever Form: Lever return springs are contained inside the lock case rather than in the trim, simplifying trim removal and reinstallation during service. The L lever complies with the American Disabilities Act; consult local authorities to confirm applicability to your specific jurisdiction and occupancy.

Key Product Features

• 16 Million Cycle Endurance: The Sargent 8200 Series completed UL cycle testing at 16 million cycles — 16 times the ANSI/BHMA A156.13 Grade 1 requirement (Verification ID: V584148). That margin matters on storeroom doors cycled dozens of times daily across a long service life.
• ANSI/BHMA A156.13 Series 1000 — Operational and Security Grade 1: Certified at both the highest operational and security grades with standard trims. Note: LFIC and SFIC cylinder options (offered on this listing) do not meet Security Grade 1 requirements — specify the LA keyway or LC less-cylinder option when Security Grade 1 must be maintained end to end.
• 12-Gauge Heavy-Duty Wrought Steel Case: The lock case is 12-gauge wrought steel, zinc dichromate plated, at 7/64" (3mm) /.109" thickness. Cold forged steel hubs and a high-carbon steel spring cartridge complete the internal load-bearing components of the 8200 lock body.
• UL/cUL 3-Hour Fire Rating and Positive Pressure: UL and cUL Listed for A-label 4×10 single and 8×10 double (3-hour fire door) and lesser-class doors to US and Canadian safety standards; meets ANSI/UL 10C Positive Pressure Fire Test. The armored front is stamped with the letter F and the UL symbol to confirm listing at installation inspection.
• Cylinder and Keyway Options: This listing is offered in four configurations: LC (Less Cylinder), LA Keyway (standard brass cylinder, #41 / 1-1/8", two nickel-silver keys included, masterkey and construction-key capable), 60 (LFIC Less Core), and 70 (SFIC Less Core). LFIC and SFIC options do not meet ANSI/BHMA A156.13 Security Grade 1. LFIC, SFIC, and standard interchangeable-core options beyond those listed are not available on this trim.
• 10-Year Limited Mechanical Warranty: Sargent backs the 8200 Series lock body with a 10-year limited mechanical warranty (warranty limited to replacement of the lock body). The field-reversible lock body — re-handed without removing parts or opening the case — also reduces installation labor and the risk of mis-handing on complex projects.

Technical Specifications

Ordering & Installation Information

The 8204 LL requires an ANSI/SDI A250.14 door prep modified per Sargent template 7057; confirm the door is prepared to this template before ordering. The lock operates on a 2-3/4" (70mm) backset only — no other backset is available — and demands a minimum 4-1/2" (114mm) stile; narrower stiles cannot accept the mortise case. Standard door thickness is 1-3/4" (44mm), though the 8200 Series is offered for doors from 1-3/8" to 6" thick; non-standard thicknesses require separate specification. The LL trim is non-handed; the lock body is field-reversible without opening the case, so handing can be set or changed on site. Six architectural finishes are available: 626 Satin Chrome, 630 Satin Stainless, 613E Oil Rubbed Bronze Equal, 605 Polished Brass, 612 Satin Bronze, and 625 Polished Chrome. Cylinder options are LC, LA Keyway, LFIC Less Core (60), and SFIC Less Core (70). The broader Sargent 8200 Series also offers optional MicroShield® antimicrobial finish coating, electro-mechanical ElectroLynx® configurations, status indicators, push/pull ALP trim, and secure fastener options — consult your Sargent representative for those separately specified configurations. Factory lead time: 3–4 weeks.
