Don-Jo FL-208N Security Strike – 1-3/8" x 8", 13 Gauge Steel
The Don-Jo FL-208N Security Strike is a heavy-duty, single-hole security strike engineered to reinforce the door frame at the point where a key-in-knob or deadbolt latch engages. Don-Jo Manufacturing forms this strike from 13-gauge (.095) ferrous steel — robust material that resists spreading and deformation under lateral force — then cuts it to a 1-3/8" wide by 8" tall profile that distributes stress across a far greater surface area than a standard box strike. The elongated plate anchors deep into the frame behind the jamb, making it the preferred security strike specification for replacement and new-construction doors where a single bolt or latch must be adequately protected. Available in three finishes — silver lacquer (SL), bright brass (BP), and white (WH) — the FL-208N coordinates with most residential and light-commercial hardware finishes without special order.
FL-208N Security Strike Features
- 13-Gauge (.095) Ferrous Steel Construction: Thick steel plate resists deflection and bending at the latch point, providing substantially more frame reinforcement than thin-gauge commodity strikes.
- Single-Hole Design for Key-in-Knob or Deadbolt: One precisely centered latch cutout accommodates a single bolt or latch, keeping the plate optimized for the application without unnecessary openings that reduce plate integrity.
- Extended 8" Plate Height: The tall profile spans the full strike zone and anchor-screw range of the door frame, spreading stress across multiple framing members rather than concentrating load at a single fastener line.
- 1-3/8" Plate Width: Sized to fit standard residential and light-commercial door frame rabbets, allowing a clean, flush installation without frame modification on most applications.
- Three Finish Options: Silver lacquer (SL), bright brass (BP), and white (WH) finishes are stocked at the Don-Jo facility, making it practical to match the most common door and frame hardware palettes.
- Shelf Pack of 10: Packed in quantities of ten, the FL-208N is a practical choice for contractors, locksmiths, and property managers performing multi-unit installations or maintaining on-truck inventory.
