Don-Jo FL-208NM Security Strike – 1-3/8" x 8", 13 Gauge Ferrous Steel

The Don-Jo FL-208NM Security Strike is a heavy-duty security strike engineered for commercial and institutional door applications where a standard-weight strike simply will not hold up. Manufactured by Don-Jo Manufacturing, this 13-gauge (.095) ferrous steel security strike measures 1-3/8" wide by 8" tall and features a single latch hole with a universal center mortise hole layout, making it a straightforward replacement or new-construction fit across a wide range of wood and metal door frames. Specifiers and locksmiths working on high-traffic or high-security openings will appreciate the full 8-inch face plate height, which bridges frame damage and covers the strike area far beyond what a 4-inch box strike can protect. The FL-208NM is available in three finish options — silver lacquer (SL), bright brass (BP), and white (WH) — allowing coordination with the surrounding hardware and frame finish.

FL-208NM Security Strike Features

• Heavy 13-Gauge Construction: Formed from 13 ga. (.095) ferrous steel for a rigid, high-cycle strike face that resists bending and deformation at the door frame.
• Full 8-Inch Height: The tall 8" x 1-3/8" face plate spans the strike zone generously, covering frame imperfections and providing a clean, finished appearance on commercial openings.
• Universal Center Mortise Hole: The single latch hole with universal center layout accommodates common latch bolt configurations, simplifying specification across mixed hardware schedules.
• Security Strike Classification: Designed and cataloged as a security strike — not a latch guard or remodeler plate — for direct frame mortise mounting in new-construction and retrofit scenarios.
• Three Finish Options: Choose silver lacquer (SL), bright brass (BP), or white (WH) to match the surrounding door hardware and frame finish without ordering a custom color.
• Non-Handed Design: The FL-208NM is not handed, eliminating the need for separate left-hand and right-hand SKUs and reducing inventory complexity.
• Ferrous Steel Material: Ferrous construction ensures compatibility with standard frame prep tools and provides a solid magnetic interface where door sensors or magnetic holders are in use.
