The DON-JO 2SDSSL is a security strike plate designed for deadbolt applications in commercial and residential door assemblies. This reinforced strike provides a hardened mounting surface at the door frame, replacing the standard short-lip strike that ships with most deadbolt locksets. At 7.75 inches in length and 4 inches in width, the extended plate spreads kick-in force across a larger frame area, reducing the risk of frame failure under impact. The silver coated finish resists corrosion and coordinates with common hardware finishes. Door hardware specialists, locksmiths, and security contractors are the primary installers.
This security strike is suited for single-door residential and light commercial installations where deadbolt security needs to be upgraded beyond standard OEM hardware. The extended plate length is particularly effective on hollow-core frames and older construction where the original strike mortise offers minimal wood engagement. Sold individually, with a case quantity of 10 units for trade stocking orders.
Designed as an OEM-style replacement or upgrade security strike for residential and light commercial deadbolt lockset installations.
Installation is typically performed by a licensed locksmith or door hardware technician. Before installation, ensure the door and frame are plumb and that the existing deadbolt throw aligns with the new strike mortise location. Secure mounting with fasteners that penetrate through the door jamb and into the structural framing stud for maximum holding strength. Follow applicable building and security codes for frame reinforcement requirements in your jurisdiction.
