Don-Jo 504-FE Stainless Steel Edge Guard | 12" Mortise Lock Door Reinforcer

The Don-Jo 504-FE Stainless Steel Edge Guard Plate is a high-security architectural solution designed to protect and reinforce the critical locking edge of commercial doors. Measuring 12" high x 1" deep, this heavy-duty door edge guard is specifically engineered for 1-3/4" thick doors equipped with a mortise lockset. It provides a rigid steel barrier that prevents the door from splintering or spreading, making it the premier solution for door edge reinforcement in high-traffic environments like schools, hospitals, and office complexes.

Featuring a standard 8" mortise lock edge prep, the 504-FE is designed to fit seamlessly around the faceplate of your existing mortise hardware. This extended 12-inch plate acts as a superior solution for door restoration, covering unsightly "ghosting," wood splitting, or structural damage often found in aging or compromised commercial entryways.

Key Features & Performance

• Mortise Lock Optimized: Precision-prepped for a standard 8" mortise lock edge, ensuring the latch and deadbolt function perfectly while the surrounding door material is fully protected.
• 1-3/4" Commercial Fit: Tailor-made for the standard thickness of commercial hollow metal and solid-core wood doors, providing a flush, professional mount.
• Extended 12-Inch Protection: The oversized height distributes stress across a larger area of the door leaf, acting as a high-performance remodeling scar plate that hides major imperfections.
• Premium 630 Stainless Steel: Manufactured from US32D / 630 Satin Stainless Steel, offering industrial-grade corrosion resistance and a modern, brushed finish that coordinates with Grade 1 architectural hardware.
  
• Enhanced Door Security: Provides a permanent solution for commercial door security by shielding the door's core from prying tools and preventing "kick-in" failures at the mortise pocket.

Why Choose the Don-Jo 504-FE?

The Don-Jo 504-FE is the industry-standard "problem solver" for facility managers.

It is a cost-effective and permanent solution for door restoration, delivering the industrial-strength security and polished aesthetic required for high-security municipal and commercial facilities.
