Don-Jo FL-212NM Security Strike | 1-3/8" x 12" | Silver Lacquer, Bright Brass, White

The Don-Jo FL-212NM Security Strike is a heavy-duty 13-gauge (.095) ferrous steel security strike measuring 1-3/8" wide by 12" tall — purpose-built to reinforce the door frame at the latch point and resist forced-entry attempts that exploit a standard-depth strike box. Don-Jo Manufacturing designed this security strike with a single latch hole and a universal center mortise hole, making it a direct upgrade for residential and light-commercial doors where frame-to-latch engagement needs to be hardened without a full frame replacement. Available in three finish options — silver lacquer (SL), bright brass (BP), and white (WH) — the FL-212NM integrates cleanly with painted or natural-finish frames while delivering the rigid steel backing that a standard thin-gauge strike cannot provide. Specifiers, locksmiths, and contractors sourcing a heavy-gauge security strike for door reinforcement projects will find the FL-212NM a practical, dimension-specific solution.

FL-212NM Security Strike — Key Features

• Heavy 13-Gauge Steel Construction: Manufactured from 13 ga. (.095) ferrous steel, this security strike delivers a rigid, hard-to-deform face plate that outperforms lighter-gauge replacement strikes at the frame mortise.
• Full 12" Coverage Height: The 12" tall profile distributes load across a significantly greater section of the door frame, reinforcing the jamb well beyond the latch point alone.
• Universal Center Mortise Hole: A single latch hole with a universal center mortise hole layout accommodates common latch bolt configurations without requiring custom routing of the jamb.
• 1-3/8" Strike Width: The narrow 1-3/8" width is sized to fit standard door frames without encroaching on the door stop or requiring stop modifications.
• Three Finish Choices: Offered in silver lacquer (SL), bright brass (BP), and white (WH) to coordinate with finish hardware and frame paint on a wide range of openings.
• Not Handed: A non-handed design means the same SKU installs on left-hand or right-hand openings — no separate order required for each swing direction.
• Don-Jo Manufacturing Quality: Produced by Don-Jo Manufacturing, a recognized supplier of door reinforcement hardware to the locksmith and commercial door trades.
