Don-Jo AST-2134M Security Strike – 1-3/4" x 18", 13 Gauge Steel, Silver Lacquer / Bright Brass / White

The Don-Jo AST-2134M Security Strike is a heavy-duty, 13-gauge (.095) ferrous steel security strike measuring 1-3/4" wide by 18" tall — engineered to reinforce the strike zone on doors where a standard short strike leaves the jamb vulnerable. Don-Jo designed this security strike with a universal center mortise hole and a single latch hole to align with a wide range of door preps, making it a practical solution for retrofit and new-installation applications alike. It is available in three finish options: silver lacquer (SL), bright brass (BP), and white (WH), allowing coordinators and specifiers to match existing door hardware without sacrificing protection. The extended 18" plate length distributes load across a much greater section of the door jamb than a conventional strike, addressing the core weakness exploited in forced-entry events at the strike point.

AST-2134M Security Strike – Key Features

• Heavy 13-Gauge Steel Construction: At .095" thickness, this ferrous steel security strike delivers substantial resistance at the latch point — a meaningful upgrade over lighter-gauge commodity strikes.
• Extended 18" Plate Height: The tall 18" profile spreads impact force across a wide section of the door frame, reinforcing the most common forced-entry target on any hinged door.
• Universal Center Mortise Hole: The mortise hole with universal center accommodates a broad range of door preps, simplifying retrofit installations without extensive frame modification.
• Single Latch Hole: Configured for single-latch applications, keeping the plate compatible with standard cylindrical and mortise latchbolt setups.
• Three Finish Options: Available in silver lacquer, bright brass, and white to coordinate with existing door hardware and frame finishes.
• Not Handed: The AST-2134M is not handed, so a single SKU covers both left- and right-hand door configurations — no special ordering required for swing direction.
• Shelf Pack of 10: Packaged in quantities of 10, well-suited for contractors, locksmiths, and facilities managers ordering for multi-door projects.
