Don-Jo FL-212WM Security Strike – 1-3/4" x 12" Ferrous Steel, 13 Gauge

The Don-Jo FL-212WM Security Strike is a heavy-duty security strike engineered for commercial and institutional door applications where a standard-depth strike plate simply isn't enough. Manufactured by Don-Jo Manufacturing from ferrous steel at 13 gauge (.095"), this 1-3/4" wide by 12" tall security strike delivers the rigidity and coverage that high-traffic or high-risk openings demand. The full 12" height wraps the door jamb area beyond the latch pocket, significantly reducing the exposed gap between door edge and frame that pry tools can exploit. A single mortise-hole, universal-center latch opening accommodates the bolt geometry found on most commercial cylindrical and mortise locksets without additional machining. Available in three finish options — silver lacquer (Don-Jo SL), bright brass (Don-Jo BP), and white (Don-Jo WH) — the FL-212WM suits a range of door hardware finish programs without special finishing orders.

FL-212WM Security Strike – Key Features

• Heavy 13-Gauge Ferrous Steel (.095"): Thick-gauge construction provides the rigidity commercial security strikes require, resisting deformation under lateral door stress.
• Full 12" Strike Height: Extended coverage along the jamb protects a larger portion of the latch area compared to short-format strike plates, reinforcing the most vulnerable point of a commercial door opening.
• Universal Center Mortise Hole: Single latch hole with universal center geometry integrates with a wide range of cylindrical and mortise latch bolts without custom prep work.
• Three Ready Finishes: Silver lacquer (SL), bright brass (BP), and white (WH) finishes allow the security strike to coordinate with existing door hardware without a special-order finish program.
• Non-Handed Design: The FL-212WM is not handed and installs on either hand of door without a separate SKU, simplifying specification and inventory.
• Commercial Shelf Pack of 10: Packaged in quantities of 10, making it practical for facility managers, locksmiths, and door distributors maintaining jobsite stock.
