How to Install a Casement Window Lock
Home security is becoming more essential and casement window locks are a vital ingredient in maintaining the security of your home. Adding locks to any window or door is a very simple process and the time involved is around twenty to thirty minutes. It is time well spent to protect the goods and valuables in your home. This is an example of one type of lock, but there are a few types to choose from.
Step 1 – Casement Windows
Casement Windows are not the same as sash windows. They open outward from a vertical center point and they are held against the frame by two hinges on the sides. Therefore, in order to mark your windows to accept the lock you will need to have the windows completely closed. So, close the windows before you start.
Step 2 – Placing the Marks
The lock needs to be placed in a position where it cannot be tampered with from the outside. Place the ‘keeper’ part of the lock on the left hand window frame approximately one inch up from the bottom ledge. Mark with a sharp pencil where the screw holes are. Push the tip of the pencil through each screw hole and make sure it is level. Also ensure that the ‘keeper’ hook is facing upward for the latch to sit in.
Step 3 – Placing the Lock
Taking the ‘latch’ half of the lock and place that in the exact same line as the ‘keeper’ half. Allow approximately 2/16 of an inch gap between the two parts so that when you open the window outward they do not get caught on each other. You can put a couple of pilot screws in and just check the limit if you are not sure.
Step 4 – Setting the Lock
If the windows are made of wood you can use a sharp scribe to create a small pin hole in which to situate your screws. If your windows are uPVC, aluminum or vinyl then you will need to drill pilot holes in the material in order to situate the screws. Mark with the pencil point again, where the screw holes are for the ‘latch’ half of the lock.
Step 5 – Fitting the Lock
Screw the ‘keeper’ half down first. There will probably be four screws, one in each corner. Screw those in tightly and then place the ‘latch’ half of the lock on its marking on the opposing window. Make sure the two line up perfectly and there is a sufficient gap to allow for opening. Also, make sure the ‘latch’ itself is actually in the ‘up’ position and then lower into the ‘keeper’. Place the screws in the holes and tighten.
Step 6 – Finishing Up
Once all the screws are tightly secured and the window lock is in place, put the ‘latch’ up and open the window and make a test run of the lock. You should have a clearance between the two halves of the lock and the window should open and close without any difficulty. If you are satisfied then close the window and lock it!
