How to Install a Casement Window Latch How to Install a Casement Window Latch
A casement window latch will keep your windows locked at all times. With casement windows, the windows are locked with mechanisms called fasteners or latches. Different manufacturers of the hardware refer to them as different things, but you will see when you are searching for replacement parts, the name is interchangeable. The latch is a metal clasp which pivots and slides into a stationary metal fitting, creating a lock to keep the window closed. One side will be affixed to the inside window frame and one side will be affixed to the window sash. There are different configurations of latching mechanisms, some close on the side of the window and some on the bottom of the window. These are installed in the same basic manner. It is a simple process to install latches. Below you will find a step by step process for how to install a casement window latch.
Step 1 – Decide on Positioning
You need to establish if the latch will be on the side or the bottom of the window. If you are fastening on the side of the window, be sure to buy a right side or left side latch. Some latches can be used for both bottom and side installations and are adjustable for left to right.
Step 2 – Mark Holes
It is easiest to install new hardware when the window is out of the wall and laying on a flat surface by measuring and marking your holes is easier with it in place. If you are installing new windows and haven’t placed the window yet, you may want to install the part that goes on the window first (the non-moving part) and the moving part on the inside window frame after the window is in place.
On a window in place, hold the latch in a closed and locked position in the location where it will be attached. Mark the screw holes.
Step 3 – Insert the Screws
If you are comfortable using a drill with a light touch, being careful of the window glass, pressure and vibrations, you can drill starter holes in the window using a small drill bit and drilling very shallow small holes. Position the hardware over top of your holes and screw in the screws in with your drill. It is suggested that you use a screwdriver than a drill.
For the placement of the hardware on the interior window frame, you can use an electric drill without fear of damage. Drill guide holes, position the hardware, and screw in the screws. If using a screwdriver, you can skip the guide hole step.
Step 4 – Check Your Work
If your measurements were accurate and the hardware did not move when you installed it, your latch should line up and when you turn the clasp, the window should lock firmly.
