Sargent 8204 OJ Trim Storeroom or Closet Function Mortise Lockset

The Sargent 8200 Series 8204 mortise lockset in OJ trim — O Rose (2-3/4" dia) paired with the J lever — brings the clean, low-profile sightline of a round rose to storeroom and closet openings that demand Grade 1 security without visual bulk. Functioning to ANSI F07 Storeroom or Closet, the 8204 keeps the outside lever locked at all times: entry is by key only, while the inside lever always provides free egress. There is no deadbolt, no thumbturn, and no occupancy indicator — a deliberate, tamper-resistant configuration suited to supply rooms, file storage, and back-of-house closets wherever controlled single-point access is the requirement. Built on the patented Sargent multi-function lockbody and certified to ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, this is a specifiable, finish-coordinated solution for institutional and commercial interiors.

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

The 8204 defines a strict access boundary: the outside lever is locked at all times and yields only to a key, while the inside lever remains freely operational for unimpeded egress. A stainless steel auxiliary deadlatch and a 3/4" anti-friction latch work together to secure the door positively on every closing, with no deadbolt and no thumbturn required or present.

• Key-Only Outside Entry: The outside trim is locked at all times — a key is the sole means of retracting the latchbolt from the corridor side. This resists unauthorized lever manipulation, making the 8204 the correct function for storerooms, supply closets, and any space requiring controlled single-point access.
• Always-Free Inside Egress: The inside lever always retracts the latchbolt freely, with no key, no thumbturn, and no unlocking step required. Because egress is never impeded, occupants can exit at any time — a critical life-safety characteristic for occupied storage and utility spaces.
• Stainless Steel Auxiliary Deadlatch: The non-handed auxiliary deadlatch is stainless steel and engages automatically when the door closes against the strike. It prevents the latchbolt from being slipped or retracted by external pressure without a key, adding a second line of engagement independent of the primary latch.
• Anti-Friction One-Piece Latchbolt: The stainless steel latchbolt delivers a 3/4" (19mm) throw and is built as a single anti-friction piece, so the door closes smoothly and positively each time. The multi-function 8200/7800 lockbody hosts the 8204 function alongside up to eight other functions in one case, giving specifiers flexibility to standardize on a single lockbody across a project.

O Rose (2-3/4" dia) and J Lever — Refined Round-Rose Trim

Where a full escutcheon plate would dominate a door face, the O Rose at 2-3/4" diameter keeps the mount compact and the lever visually prominent. Paired with the J lever, the combination reads as contemporary institutional hardware — substantial in the hand, restrained on the door. Because the J lever trim is non-handed, no handing declaration is needed at the time of order.

• Low-Profile O Rose Carrier: At 2-3/4" diameter, the O Rose presents a smaller footprint than an escutcheon plate, allowing the J lever's form to anchor the visual rather than the surround. This makes the OJ combination well suited to interiors where architectural detailing is intended to read cleanly.
• 30-Degree Lever Rotation: Only 30 degrees of lever travel is required to fully retract the latchbolt. That shallow arc reduces the wrist torque demanded of users and contributes to operation that complies with the Americans with Disabilities Act — consult local authorities to confirm applicability to your specific installation.
• Through-Bolted, Interchangeable Trim: Trim, including the J lever and O Rose, is through-bolted and fully interchangeable between rose and escutcheon configurations. Lever springs are contained inside the lock case rather than in the trim, which simplifies field installation and reduces the chance of spring misalignment during a trim swap.
• Six Architectural Finishes: The OJ trim is offered in 626 Satin Chrome (US26D), 630 Satin Stainless (US32D), 613E Oil Rubbed Bronze Equal (US10BE), 605 Polished Brass (US3), 612 Satin Bronze (US10), and 625 Polished Chrome (US26), covering the full range from warm traditional bronze to cool contemporary stainless.

Key Product Features

• ANSI/BHMA A156.13 Series 1000 — Operational Grade 1 and Security Grade 1: The 8204 OJ is certified to the highest commercial mortise lock grade for both operational performance and security with standard trims. Note that LFIC and SFIC cylinder options offered on this listing do not meet Security Grade 1 requirements.
• 16 Million Cycle Verified Durability: The 8200 Series completed a UL "above and beyond" cycle test at 16 million cycles — 16 times the ANSI/BHMA A156.13 Grade 1 requirement — with Verification ID V584148. That test result speaks directly to the total cost of ownership in high-traffic institutional and commercial applications.
• 12-Gauge Zinc-Dichromate-Plated Steel Case: The lock case is fabricated from 12-gauge heavy-duty wrought steel at 7/64" (3mm) thickness and finished with zinc dichromate plating. The inside front is 1/8" cold-rolled steel, holding the lock securely in the door preparation.
• Cold Forged Steel Hubs and High-Carbon Steel Spring Cartridge: The 8200 Series specifies cold forged steel hubs — not the sintered iron copper-infiltrated hubs of the 7800 line — combined with a high-carbon steel spring cartridge. This material specification underpins the hub strength and cycle life the 8200 line is designed to deliver.
• UL/cUL 3-Hour Fire Door Listed and UL 10C Positive Pressure Rated: The lockset is UL and cUL Listed for A-label 4×10 single and 8×10 double (3-hour fire door) and lesser-class doors, and it 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 in the field.
• 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 confidence the manufacturer places in the 8200's construction and component quality.

Technical Specifications

Ordering & Installation Information

The 8204 OJ mortise lockset requires a door prepared to ANSI/SDI A250.14 modified per template 7057. The lock is built for a 2-3/4" (70mm) backset only — no other backset is available — and the door stile must be a minimum of 4-1/2" (114mm) to accommodate the case; undersized stiles are a common ordering error on narrow-stile aluminum doors, so confirm stile width before specifying. Standard door thickness is 1-3/4" (44mm), though the 8200 Series is offered for door thicknesses from 1-3/8" to 6" when required. The lock body is field reversible without removing parts or opening the case, making handing changes straightforward on the jobsite; the J lever trim is non-handed and requires no separate handing selection. Cylinder options on this listing are: LC (Less Cylinder), LA Keyway, 60 — LFIC Less Core, and 70 — SFIC Less Core; note that LFIC and SFIC options do not meet ANSI/BHMA A156.13 Security Grade 1. The standard cylinder is brass, size #41 (1-1/8"). Six finishes are available. Factory lead time is 3–4 weeks. For projects with specialized requirements, the broader 8200 Series also offers MicroShield antimicrobial finish coatings, electro-mechanical configurations with ElectroLynx connectors, status indicator options, and vandalism-deterrent trim with secure fasteners — all separately specified.
