American Standard ANSI Grade 1 Fire-Rated Door Lock - Product Features & Advantages
- ANSI/BHMA A156.13 Grade 1: Top-Tier Commercial Security: Undergoes 2,000,000+ cycle testing and strict strength/security evaluations—outperforming Grade 2/3 locks. Ideal for high-traffic commercial spaces like office buildings, hotel lobbies, and retail stores where durability and anti-tamper performance are critical.
- UL Fire-Rated: 3-Hour Protection for Life Safety: Maintains lock integrity at 1,700°F for 3 hours—compliant with US fire codes (NFPA 80) for egress doors in hospitals, schools, and commercial towers. Ensures safe evacuation during fires.
- Corrosion-Resistant Stainless Steel Construction: Built with SUS304 stainless steel (SUS316 optional for coastal/industrial areas), resisting rust from humidity, cleaning chemicals, and salt air. Perfect for hotel pool areas, office restrooms, or coastal residential properties.
- Passage Latch: Lever Operation from Both Sides: The latch bolt is always operable via levers on either side—ideal for closets, office pantries, or hotel corridors where unrestricted access (no keyed entry) and quick passage are needed. Eliminates privacy lockouts common in basic latches.
- Seamless Integration with D&D Hardware Ecosystem: Matches D&D’s stainless steel door handles (matching SSS/PSS finishes) and door closers (ensures doors close properly after passage). Compatible with panic exit devices for emergency egress in commercial buildings—reducing cross-product compatibility issues.
American Standard ANSI Grade 1 Fire-Rated Door Lock - Installation Steps (ANSI-Compliant)
- Pre-Installation Preparation: - Confirm door material (wood/metal) and thickness (1-3/4" to 2-1/4" standard US doors). - Select finish (match D&D’s Stainless Steel Door Stops or door handles for aesthetic consistency). - Gather tools: ANSI-compliant drill bits, torque screwdriver, template (included with lockset), level, pencil.
- Mark & Cut Door Prep: - Use the included template to mark the lock body mortise, latch bolt hole, and lever mounting holes on the door. - Cut the mortise for the lock body (depth = lock body length) and drill the latch bolt hole (1" diameter) using ANSI-standard dimensions. - Ensure cuts are precise—ANSI Grade 1 locks require exact alignment for optimal performance.
- Install Lock Body & Latch Bolt: - Insert the lock body into the mortise, aligning the latch bolt with the drilled hole. Secure with provided stainless steel screws (tighten to 15–20 in-lbs torque per ANSI specifications). - Test the latch bolt: Operate the lever to extend/retract the bolt—confirm smooth movement without binding.
- Mount Levers & Integrate Hardware: - Attach the levers to both sides of the door, ensuring the spindle connects securely to the lock body’s follower. - For commercial applications, install D&D’s door closer (adjust closing speed to 3–5 seconds for seamless passage). - If integrating with a panic exit device, connect the lock’s latch bolt mechanism to the exit device’s rod (follow ANSI/BHMA A156.3 standards).
- Final ANSI Compliance Testing: - Cycle Test: Operate the lever 100 times—verify smooth latch bolt movement and no loosening of components. - Fire Test Simulation: Visually inspect for proper fire-seal integration (if using fire-rated door assemblies). - Compliance Documentation: Retain ANSI/BHMA and UL certification documents for building inspector audits.

American Standard ANSI Grade 1 Fire-Rated Door Lock - Production Process & Quality Control
D&D’s specialized process ensures each DDAL01 lock meets ANSI Grade 1 and UL standards:
- Material Sourcing (ANSI-Compliant): - Select SUS304/SUS316 stainless steel from US-certified mills; test via XRF to confirm chemical composition (meets ASTM A240 for ANSI compliance). - Reject batches with impurities that could compromise strength or corrosion resistance.
- Precision Machining (Grade 1 Tolerances): - Lock Body & Latch Bolt: CNC-machined to ±0.005" tolerance—ensures ANSI Grade 1 smooth operation and strength. - Levers: Die-cast with ergonomic contours; edges deburred for user safety; finished with PVD/electropolishing for durability.
- Assembly & ANSI Calibration: - Assemble in ISO 8 cleanrooms to avoid debris in mechanisms; use aerospace-grade lubricants for 2,000,000+ cycle life. - Calibrate latch bolt tension to 5–7 lbf (meets ANSI Grade 1 operation force requirements).
- ANSI & UL Testing: - ANSI Cycle Test: 100% of units undergo 5,000 pre-shipment cycles—reject any with friction increase. - UL Fire Test: Random samples endure 3-hour fire testing at 1,700°F—only locks that maintain integrity proceed. - Strength Test: Sample units withstand 900 lbf force without deformation—verifies ANSI Grade 1 impact resistance.
- Packaging & Compliance Documentation: - Pack in ANSI-labeled boxes with UL certification stickers, installation template, and compliance certificates. - Final inspection: Verify ANSI Grade 1 markings, finish quality, and operation—reject batches with ≥0.5% defects. Include batch-specific test reports for buyer audits.
