What do you do when you have a door that has a hole pattern for a previous lockset and the old hole and the new hole patterns don’t match?
This is common when switching from, or to, door handle sets instead of a doorknob/deadbolt combination.
You could replace the door or use a door hole filler, but replacing a door is NOT the most affordable way to cover doorknob holes or cover deadbolt holes. Patching the door hole with door putty or other filler requires some skill, and the hole patches often crack over time.
To affordably and easily cover a doorknob or deadbolt hole, you can use a door-hole cover plate to cover holes left behind by a single lock. Or, you can use push plates or door wraps, for when there are multiple holes to cover (like when switching to/from handle sets) or large air voids to cover/patch (like those left when switching from mortise locks to cylindrical locks).
Cover Doorknob Holes and Deadbolt Holes with Filler Plates
Hole filler plates, also called hole cover plates, are the least expensive way to cover a door hole. They work well to cover the round holes left by cylindrical locks such as deadbolts and door knobs. They can cover holes up to 2-1/2 inches.
Door hole cover plates cover the hole on both sides of the door by installing a flat plate over each side. They are held together by a connector bolt and cap (there is a screw that screws into a receiving cylinder). The cap side is smooth; be sure to install this with the connector bolt on the inside of the door so it cannot be removed from the outside.
They come in a variety of hardware finishes to match your existing door hardware. You can also buy them primed and ready to paint any color to match the door.
Hole Filler Plates are available for as little as $3 on Amazon. If desired, you can also fill door latch holes using a door latch hole filler plate. These are smaller, square plates designed to fill the latch holes on the frame side of the door. Latch hole filler plates are also available on amazon for a few dollars.
Door hole cover plates are usually designed for 1-3/4 inch doors, but you can buy a longer screw to use at Home Depot for a thicker door.
Covering Multiple Holes or Door Cavities on a Door
Sometimes, an existing door hole isn’t round at all.
This is a photo of an old Schlage brand handle set called the E-series. The hole prep for this is a large rectangle hole about 2 x 6 inches to hold everything within what’s circled in the photo. In the 70s and 80s, several manufacturers were designing handle sets similar to this.
Since these were made, most manufacturers have redesigned their hardware for a ‘standard door prep’ using cylindrical holes of 2-1/8th inches. But previous to this, door hole prep wasn’t standardized, and some interesting hole patterns must now be covered when replacing old door hardware with modern door hardware.
Push Plates
Push plates are designed to protect a door when it is pushed open . They are usually 4 x 16 inches but can be purchased in different sizes and many different finishes. They can be ornate, but for repairing door holes you’ll want a basic flat door plate so that the door hardware can easily install over it.
In the photo showing a brass push plate under a handle set, the customer had us replace her old handle set using this method. It’s not as pretty as it may have been with a new door, but a couple of plates installed to cover existing door holes is drastically cheaper than replacing a solid wood door. You can pick up door push plates to fix door holes for around $13 on Amazon.
To cover door holes and cavities with push plates, you need to purchase two of them, one for the inside and another for the outside of the door. You will also need to drill through them once they are installed to accommodate the new door hardware you are putting on.
Door Wraps
Door Wraps (also called wrap-around plates or door reinforcers) are designed to help strengthen a door and prevent the door from being kicked in. Wraps can also be used to cover multiple door holes or a large door cavity.
The advantages to using a door wrap over a push plate are: only one piece is installed, you get an additional security benefit by wrapping the door in steel, and some of them will be pre-drilled for standard door hardware.
This door, for example, had a very old (and no longer available) mortise lock body installed. When removed, a mortise lock body leaves roughly a 5” by 4” inch void in the door. Once removed, there’s no place for a cylindrical lock to be attached to the door.
Plus, mortise body locks are very expensive! So many customers opt to have a less expensive cylindrical lock installed.
A door wrap will cover the door voids and strengthen the door.
These, too, are available in all the common hardware finishes, and they have many types of hole preps pre-drilled into them to suit the needs of the new lock installation.
Door wraps are designed for doors of a specific and standard thickness. For thick doors, they can be custom made. This can add some expense, but then again, a custom made thick door is much MORE expensive than that.
Many door wraps can be found on Amazon and are very affordable.
