In installing a new door knob for your office or home, you have to remember that the existing holes of your former door knob should fit in the new one. This will help you in having a hassle-free way of removing the old door knob and replacing it with the new one. Thus, in purchasing a door knob, you must have the following information:
- The type of lock – Is it cylindrical, tubular or rim?
- Diameter of the cylinder and latch holes/size of rim;
- Distance from the edge of the door to the center of the door knob;
- Thickness of the door; and
- Direction of the door when it opens – Is it inward or outward?
Now, that you’ve determined and have successfully purchased a door knob that fits in just like the old one, you must do the following steps in installing it:
Step 1 – Removing of old door knob
To remove the old door knob, all you have to do is release the shank button with a small screwdriver before removing the mounting plate. Afterward, unscrew the latch assembly from the edge of the door for it will enable you to remove the remaining parts of the old door knob.
Step 2 – Installing of new deadbolt
To install the new deadbolt, using a hole saw, drill two holes in the door wherein one is located in the face for lock’s body and the other one in the edge for accommodating the bolt.
Step 3 – Measuring of the height for the door handle
You can do various ways of getting the height of the door handle. First choice is measuring the height of the handles on other doors in the house. The second one is using the height provided by the instruction of the door handle kit you’ve purchased. Or use the standard size of door handle height which is 1050 mm off the floor.
Tip: while working on your door knob installation, use a wedge to keep the door from moving.
Step 4 – Marking the door handle
In drilling for the spot where the door handle will go, you may use the template provided in your door handle kit. Mark the spots where you will be drilling to avoid mistakes.
Step 5 – Drilling pilot holes
In drilling the pilot holes for the front, back and side of your door, you may use a 2mm drill bit. Just remember that to avoid the wood on the opposite side to splinter you should square to the door. Once you have drilled the pilot holes, next thing you have to do is insert a larger drill bit in the cordless drill. This will make all the pilot holes you’ve initially made larger.
Step 6 – Drilling a hole for the spindle
In drilling a hole for the spindle, you may use a 25mm spade bit attached to a cordless drill. Drill the bit to the center of the hole on the front of your droll and repeat this to the other side.
Step 7 – Drilling a hold for the barrel
Still using the spade bit attach to the cordless drill, make a hole on the side of the door where you will be inserting the barrel.
Step 8 – Marking around the faceplate
To mark around the faceplate, use a pencil to draw around the face plate after inserting the latch from the door handle into the hole you have previous drilled in the side of the door. Then use a sharp knife to cut around the outline.
Step 9 – Chiseling a hole for the latch
Using a chisel and a hammer, make a hole for the latch. Chisel inside the hole for the latch to fit.
Step 10 – Attaching of latch to the door
You can now insert the latch into the side of door and drill pilot holes where the screws will attach the latch of the door.
Step 11 – Installing of striker plate
For this step to be possible, you must close the door a little bit to make a mark on the door frame. Hold the striker plate against the door frame and mark the top and bottom of the striker plate on the door frame.
Step 12 – Drilling a hole for the striker plate
Drill a pilot hole in the center on the inside of the door frame by using the mark where the middle of the barrel is. After that, drill into the pilot hole using again a 25mm spade bit attached to the cordless drill.
Step 13 – Drawing around the striker plate
Similar with what you have done with the faceplate, using a pencil to draw around the striker plate, hold it up against the hole you drilled on the inside of the doorframe. You may use a knife to cut around the outline of the striker plate.
Step 14 – Chiseling the recess for the striker plate
A recess for the striker plate should be done using a chisel and hammer. When you’re done, insert the striker plate to guarantee it sits flush.
Step 15 – Attaching of striker plate
To attach the striker plate, you must use a 2mm drill bit to make two pilot holes for the screws. You may use a cordless drill in securing these screws at the top and bottom part of the striker plate.
Step 16 – Attaching of handles
You will need to remove the faceplates from the two handles as part of your second to the last step. After which, you may now insert the two grub screws in the smaller holes in the door as well as the bolt in the bigger hole. The face plate then should be placed on one of the handles before inserting a crew into one of the holes of it and slipping the handle over the barrel. Repeat these steps to attach the other door handle.
Step 17 – Attaching of face plates
The last step you have to do is sliding of the faceplate over the door handle and put it into place. Using the allen key, you can lock and secure the faceplates before testing the opening and closing the door.
