Don-Jo FL-212W4 Security Strike – 1-3/4" x 12", 13 Gauge, Two Latch Holes, Silver Lacquer / Bright Brass / White

The Don-Jo FL-212W4 is a heavy-duty security strike engineered for commercial and institutional doors that require robust latch-bolt protection beyond what a standard strike plate can provide. Manufactured by Don-Jo Manufacturing from ferrous steel at 13 gauge (.095"), this security strike measures 1-3/4" wide by 12" tall and incorporates two latch holes sized for 3-5/8" or 4" centers, making it a dependable solution for double-latch or double-bolt door preps on active commercial openings. The extended 12" height covers a generous strike zone, helping to reinforce the door frame and door jamb area against forced-entry attempts. Available in three finish options — silver lacquer (Don-Jo SL), bright brass (Don-Jo BP), and white (Don-Jo WH) — the FL-212W4 can be matched to the hardware finish specified for the opening. This security strike is not a latch protector, latch guard, remodeler plate, or scar plate; it is a purpose-built security strike intended for installation at the door frame strike location on commercial hollow-metal or wood-frame doors.

FL-212W4 Security Strike – Key Features

• Heavy 13 Gauge (.095") Ferrous Steel Construction: Provides substantial frame-reinforcing mass at the strike location, suited to high-traffic and security-sensitive commercial openings.
• Extended 12" Height: Covers a large strike zone along the door jamb, accommodating varied latch-bolt positions and adding coverage to the frame area around the strike.
• Two Latch Holes at 3-5/8" or 4" Centers: Factory-prepped for double-latch door hardware configurations at the two most common commercial latch-center spacings.
• 1-3/4" Width: Sized to fit standard commercial door frame rabbets and mortise stop profiles without requiring frame modification on most applications.
• Three Finish Options: Silver lacquer (SL), bright brass (BP), and white (WH) allow the installer or specifier to coordinate with the door hardware finish schedule.
• Not Handed: A single SKU installs on either hand of door, simplifying procurement and inventory.
• Shelf Pack of 10: Packaged in units of 10, practical for contractors and distributors stocking multiple openings on a project.
