The DON-JO MST261SL is an ANSI-standard strike plate designed for use with mortise and cylindrical locksets in commercial and residential door hardware applications. Finished in silver plated, this strike provides a clean, durable surface at the door frame to accept the latch bolt and deadbolt. Measuring 4.85 inches in length, 1.85 inches in width, and 0.3 inches in height, it fits standard door frame preparations. Door hardware installers and locksmiths rely on this type of strike for consistent latch engagement and frame reinforcement on standard door assemblies.
The MST261SL is suited for interior and exterior door applications where an ANSI-pattern strike is specified. It installs into the door frame strike pocket and pairs with cylindrical or mortise locksets that require a standard ANSI strike pattern. This strike is sold individually and is a practical replacement or new-construction component for door hardware projects in light commercial and residential settings.
Designed as an OEM-style replacement or new-installation ANSI strike for standard residential and light commercial door frames that accept a 4.85-inch by 1.85-inch strike pattern.
Installation is typically performed by a licensed locksmith or door hardware technician. Ensure the door and frame are properly aligned before mortising the strike pocket to the correct depth. Remove the door from service or secure it open before chiseling the frame. Follow applicable building code requirements for strike reinforcement on exterior or high-security door applications.
