Master SOFI A4113NEOPA Flush Bolt Black Lacquered with Pin 172x25mm Mortise Type

Product Overview

The Master SOFI flush bolt with strike (A4113NEOPA) is a black lacquered mortise bolt designed for door security and stability in residential and commercial interior applications. At 172x25 mm, its compact form factor enables integration into wooden or metal doors where a concealed locking mechanism is required. Its robust construction ensures consistent performance in high-use environments.

The key differentiator of this SKU is the integrated bolt pin (bolec), which delivers additional locking strength compared to standard flush bolts without a pin. This feature mitigates the risk of door sagging and enhances security, making the model especially suited for partition doors, conference room dividers, or entrance doors in office spaces where reliability and discrete aesthetics are prioritized.
