Don-Jo FL-212N6 Security Strike – 1-3/8" x 12", 13 Gauge, Double Latch Hole, 5-1/2" or 6" Centers

The Don-Jo FL-212N6 Security Strike is a heavy-duty 13-gauge (.095) ferrous steel security strike designed to reinforce door frames against forced-entry at the latch point. Measuring 1-3/8" wide by 12" tall, this full-length strike plate covers the entire latch zone on standard commercial and residential door frames, providing significantly greater frame protection than a conventional short-plate strike. The FL-212N6 features two latch holes spaced for 5-1/2" or 6" centers, making it the right specification choice wherever a double-latch or two-bolt door prep requires a single continuous strike surface. Don-Jo manufactures this security strike from ferrous steel at 13 ga. (.095) — a gauge that delivers structural rigidity where it matters most. The FL-212N6 is available in three finish options to coordinate with frame hardware: silver lacquer (Don-Jo SL), bright brass (Don-Jo BP), and white (Don-Jo WH). Specify by model number and finish suffix to order the exact combination required for your project.

FL-212N6 Security Strike Features

• Heavy-Gauge Steel Construction: Formed from 13 ga. (.095) ferrous steel for a rigid, durable security strike that resists deformation at the frame.
• Full 12" Coverage: The 12" height spans the full latch zone, eliminating the frame gaps left by shorter strike plates and improving forced-entry resistance.
• Double Latch Hole Pattern: Two latch holes on 5-1/2" or 6" centers accommodate double-latch door preps in a single, uninterrupted strike plate.
• Narrow 1-3/8" Width: The 1-3/8" width fits standard commercial door frame lips without requiring frame modification on most hollow metal or wood frames.
• Three Finish Options: Silver lacquer (SL), bright brass (BP), and white (WH) finishes allow the security strike to blend with existing frame and hardware finishes.
• Non-Handed Design: The FL-212N6 is not handed and installs on either hand of door without modification.
• Commercial Shelf Pack: Packaged 10 units per shelf pack for contractor and distributor ordering convenience.
