Arrow BM-386A Lever Spindle — Replacement Spindle for BM Series Mortise Locks with Lever Handles

The Arrow BM-386A is a genuine replacement lever spindle engineered specifically for Arrow BM Series mortise locks fitted with lever handles on raised ('G') escutcheons. When a spindle wears, bends, or breaks, the entire lever set loses mechanical connection to the lock body — this direct-fit part restores full latch-retraction function without requiring a complete lock replacement.

Facility managers, maintenance contractors, and locksmiths sourcing Arrow BM Series mortise lock parts will find the BM-386A a precise, cost-effective alternative to full lock body replacement on standard 1-3/4" commercial doors.

Key Benefits

• Direct OEM-fit replacement — designed exclusively for Arrow BM Series mortise locks with lever trim
• Raised escutcheon compatible — correct geometry for 'G' (raised) escutcheon configurations, ensuring proper lever engagement and smooth operation
• Correct door thickness — engineered for standard 1-3/4" commercial door thickness, the most common commercial door specification
• Part-level repair — restore lever function at the component level, avoiding costly full lock replacement
• Reduces downtime — stocking this spindle allows rapid in-field repair, critical for high-traffic commercial openings

Applications

• Commercial office buildings with Arrow BM Series mortise lock installations
• Institutional and education facilities maintaining existing Arrow BM Series hardware
• Replacement and repair programs for lever-trim mortise locks on 1-3/4" doors
• Maintenance and facilities management parts inventory for Arrow lever mortise lock hardware

Compatibility Note

The BM-386A spindle is compatible with Arrow BM Series mortise locks with lever handles on a raised ('G') escutcheon. Verify your existing escutcheon style and door thickness before ordering. This spindle is not designed for knob-trim BM Series locks or flat escutcheon configurations. If you are evaluating a full hardware replacement rather than a part-level repair, DoorwaysPlus can quote comparable mortise lock hardware from preferred commercial lines such as Sargent, Corbin Russwin, and PDQ — contact our support team for a comparison.
