Don-Jo FL-212N4 Security Strike – 1-3/8" x 12", 13 Gauge, Two Latch Holes

The Don-Jo FL-212N4 Security Strike is a heavy-duty, 13 gauge (.095) ferrous steel security strike measuring 1-3/8" wide by 12" tall — purpose-built for commercial and institutional doors where standard short-body strikes leave the latch bolt exposed to forced entry. Two latch holes accommodate double-bolt or double-latch configurations at 3-5/8" or 4" centers, making this security strike the right call on pairs of doors, multi-point latching, or any opening where a single-hole strike simply won't do. Don-Jo's FL-212N4 is available in three stocked finish options — silver lacquer (SL), bright brass (BP), and white (WH) — so it can be matched to the surrounding door hardware without a custom finish upcharge. Because the body runs a full 12" tall, it covers the gap between frame and stop along the entire latch zone, reducing pry-attack vulnerability across the full height of the bolt throw. Specifiers, facilities managers, and locksmiths reaching for a long-body ferrous security strike with dual latch clearance will find the FL-212N4 dimensionally and mechanically direct.

FL-212N4 Security Strike – Key Features

• Heavy 13 Gauge (.095) Ferrous Steel: Substantially thicker body than standard commercial strikes, providing the rigidity expected of a dedicated security strike application.
• Full 12" Tall Body: Extended height spans the latch zone of the door frame, limiting the gap that a pry bar or shimming tool could exploit between strike and stop.
• Dual Latch Holes at 3-5/8" or 4" Centers: Designed for doors with two latch bolts, supporting multi-point or double-latch hardware configurations at either standard centerline spacing.
• 1-3/8" Narrow Width: Fits standard commercial door frames without requiring mortising or special frame preparation beyond the existing strike pocket area.
• Three Finish Choices on One SKU: Silver lacquer (SL), bright brass (BP), and white (WH) finishes allow the security strike to coordinate with the finish of the lockset or door hardware already specified.
• Ferrous Steel Construction: Magnetic, weldable base material suited to steel door frames and hollow metal applications common in commercial construction.
• Shelf Pack of 10: Ordered in case quantities of 10, making the FL-212N4 practical for multi-door projects or service stock.
