<p>Engineered for storefront certainty, the Xiang’s SM1850-FBM Mechanical Storefront Door Lock delivers absolute owner control with a simple, patented Twist-to-Lock action—staff can lock up from the outside by turning the knob (no key, no code), while entry remains strictly by your physical key.

Purpose-built as a seamless retrofit for the industry-standard Adams Rite MS1850S, this commercial mortise deadbolt maintains heavy-duty security and upgrades daily convenience without altering your aluminum glass door. The five-minute, drill-free DIY installation drops directly into existing storefront prep, protecting your door, avoiding landlord issues, and saving about $200 in locksmith fees.

Beyond replacing the clunky Adams Rite 4510, SM1850 adds instant Stay-Open (Passage Mode) via the interior knob for business hours and a decisive Stay-Close (Anti-Pick) mode that uses a robust deadbolt with a built-in night latch—no extra latch guards needed. It’s the ideal solution for managing multiple doors: lock the front from inside, exit through a side or back door, and secure it with a twist.

Designed for mechanical longevity, the SM1850’s chassis uses a dedicated drive angle and is not interchangeable with keypad-style lock bodies.
