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. ## Features - DOOR EDGE FILLER PLATE – Use the filler plate to cover the mortise hole on the edge of your doors - BUILT TO LAST – Made of heavy gauge steel construction, the door hole cover plate comes finished in gray - EASY INSTALLATION – Simply install the door cover plate using the included screws - DIMENSIONS – The door edge filler plate measures 1-1/8 inch , and should be used to cover appropriately sized holes - PRIME-LINE GRADE – We specialize in repair and replacement hardware products for your home; Prime-Line’s commitment to quality results in repairs that look as good as the initial install, making us the go-to solution for our loyal customers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQR0D8 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #191,581 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #595 in Door Lock Replacement Parts | | Color | Gray | | Customer Reviews | 4.5 4.5 out of 5 stars (450) | | Date First Available | June 15, 2006 | | Finish | Gray | | Included Components | Door Filler Plate | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 1.6 ounces | | Item model number | U 9521 | | Manufacturer | Prime-Line Products | | Material | Steel | | Part Number | U 9521 | | Product Dimensions | 0.13 x 1.13 x 2.25 inches | | Shape | shape | | Size | 1 Count (Pack of 1) | | Warranty Description | Goods are warranted against manufacturing defects for 1 year. | ## Images ![Prime-Line U 9521 Steel Door Edge Hole Filler Plate, 1-1/8 In., Gray Finish (Single Pack) - Image 1](https://m.media-amazon.com/images/I/61uOihuu3GL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.

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.
