SUMBIN Commercial Door Handle | Vacant Occupied & Commercial Restroom Lock for Public Bathroom and Industrial Buildings UL CUL & ADA in Brush Gold
- 1. Premium Security & Fire Safety Certification：This mortise lock is engineered for critical applications, boasting the highest ANSI/BHMA Grade 1 rating for superior durability, strength, and security in commercial and heavy-traffic use. It is also a UL Listed Fire Rated Mortise Lock (compliant with standards like UL 10C), designed for fire-rated door assemblies (e.g., 3-hour rated) to help restrict the spread of fire and smoke, making it suitable for fire exits, stairwells, and compartmentalization doors.
- 2. Heavy-Duty Commercial Construction & Materials：Built for demanding daily use in commercial, office, apartment building, hotel, and hospital settings. Features a robust mortise lock body made from hardened steel or other durable metals, with a high-strength bolt (deadbolt) and reinforced strike plate to resist forced entry, repeated cycling, and abuse common in public or high-traffic doors.
- 3. Complete Mortise Lock Set for Architectural Hardware：This is a complete architectural mortise lock set designed for integration into the door edge. The package typically includes the mortise lock body (case), trim (such as lever or knob handles on both sides), a heavy-duty mortise deadbolt, the necessary faceplates, strike plate, mounting screws, and keys. It is designed to meet the specifications for commercial door mortise lock and office door mortise lock installations.
- 4. Specific Compliance & Intended Use：Clearly designed for specific code-compliant applications. As a fire exit mortise lock, it meets relevant panic/egress hardware requirements while maintaining its fire rating. Its Grade 1 fire rated mortise lock status ensures it is tested and approved for use on labeled fire door assemblies where life safety is paramount, such as in corridors of apartment buildings, hotels, and hospitals.
- 5. Professional Installation & Compatibility Notes：Intended for professional installation by a qualified locksmith or door hardware installer. Critical pre-installation verification is required: Confirm your door's fire rating label, door thickness, hand (handing), backset, and preparation for a mortise lock pocket. This lock is not a direct replacement for cylindrical locksets and requires a correctly sized mortise pocket in the door edge. Always consult local building codes and the door manufacturer's specifications before purchase and installation.
