Installing new door hardware can be an easy project that any homeowner can take on. Whether you're a seasoned remodeler or a rookie DIYer, you can update the hardware in your entire home in no time. It just takes a little preparation. Follow this door preparation checklist to make sure your hardware project goes quickly and smoothly.

Before you start installing your new hardware, you'll need to verify the holes on your door are accurately drilled. If any of the measurements on this checklist don’t match your interior and exterior doors, you’ll need to adjust the door or frame to ensure that your hardware fits.

Crossbore Crossbore

The hole’s diameter should measure 35mm, 54mm or our QuickFix preparation. Try this hack for enlarging crossbore holes from This Old House.

Backset

The distance from the edge of the door to the centre line of the crossbore should measure 60mm or 70mm for most Schlage door hardware.

Latch bore

The hole on the edge of the door, where the deadbolt or latch enters, should measure 25mm in diameter.

Door thickness

The door varies between our Schlage Series door hardware, between 30mm to 45mm thick, refer to the Schlage packaging for each product series.

Door jamb

The latch bore hole in the door jamb should measure at least 22mm in diameter and a minimum of a 12.7mm deep. A 22mm spade bit can be used to drill a larger hole, if necessary.

When installing door hardware on exterior doors, also check the door's current alignment by answering these questions:

Can I lock my door without lifting, pulling, or pushing the door?

Does my door alignment stay the same with the changing seasons?

When the door is closed, is there space for the deadbolt to extend 25mm into the frame when locked?

If some measurements such as the backset and door thickness do not match up, you may require the assistance of a carpenter or need to purchase a replacement door.

Proper preparation goes a long way toward making sure any DIY project goes off without a hitch. Installing door hardware is no different. Making sure your door is strong, free of cracks or warping, and otherwise undamaged is also an important step in helping to keep your home safe.
