## Description

The Defender Security U 9521 Stainless Steel Door Edge Filler Plate is used to cover the mortise hole on the edge of your doors. It measures 1-1/8, and should be used to cover appropriately sized holes. The door filler plate has a heavy gauge steel construction with a gray finish. It is easy to install using the included screws. For further dimensional information, please see the line drawing.

Review: Worked perfectly - I removed a door lock because it was no longer needed, and I wanted to cover the unsightly hole it left behind on the door frame, so I bought this. It fit perfectly and it looks good. Was easy to install. I am very happy with the results.
Review: Just what I was looking for - This is exactly as advertised. I used this to keep a door latched depressed (replacing the knob was not an option). Buying on desertcart may not have been the cheapest, but it saved me time. I skipped driving to the hardware store and searching for this specific part. It worked perfectly for me and came with screws.

### ⭐⭐⭐⭐⭐ Worked perfectly
*by J***Z on January 13, 2024*

I removed a door lock because it was no longer needed, and I wanted to cover the unsightly hole it left behind on the door frame, so I bought this. It fit perfectly and it looks good. Was easy to install. I am very happy with the results.

### ⭐⭐⭐⭐⭐ Just what I was looking for
*by Z***D on March 18, 2024*

This is exactly as advertised. I used this to keep a door latched depressed (replacing the knob was not an option). Buying on Amazon may not have been the cheapest, but it saved me time. I skipped driving to the hardware store and searching for this specific part. It worked perfectly for me and came with screws.

### ⭐⭐⭐⭐ Does not fit a security screen door.
*by Z***. on June 5, 2023*

This item will not fit the security screen door I purchased from Lowes. I don't know if all doors like mine have the exact same specs but the plate is a little too wide for the application. I could grind off the edge to make it fit but now the project is on the back burner. Bummer!
