Don-Jo 51-CW Stainless Steel Wrap-Around Plate | Compact 1-3/8" Door Reinforcer

The Don-Jo 51-CW Stainless Steel Wrap-Around Plate is a high-security hardware solution designed to provide targeted reinforcement for residential and light-commercial doors. Measuring a compact 4" wide x 4-1/2" high, this door reinforcer is specifically engineered for 1-3/8" thick doors. It is the ideal solution for door surface repair when the area around the lock has become cracked, splintered, or weathered, offering a clean and professional way to restore the structural integrity of your entryway.

Precision-manufactured with a 2-1/8" hole prep, the 51-CW is optimized for hardware with a 2-3/8" backset. By wrapping around the door edge and "sandwiching" both faces in industrial-grade steel, it serves as a critical solution for door security, preventing the door from splitting during a forced entry attempt or under the daily stress of high-frequency use.

Key Features & Performance

• 1-3/8" Door Specific: Precision-fit for the thinner profile of standard residential interior and exterior doors, providing a flush, low-profile fit.
  
• Compact Reinforcement: The 4" x 4-1/2" profile offers concentrated strength exactly where the lock is mounted, making it an efficient solution for door edge reinforcement.
  
• Standard 2-3/8" Backset: Features a factory-punched 2-1/8" bore positioned exactly 2-3/8" from the door edge, ensuring a "drop-in" installation for the most common residential locksets.
  
• Premium 630 Stainless Steel: Manufactured from US32D / 630 Satin Stainless Steel, providing superior corrosion resistance and a modern, brushed finish that matches high-end hardware.
• Professional Restoration: Functions as a durable remodeling scar plate, hiding finish wear and small imperfections around the lock prep for a polished, factory-clean appearance.
