How to replace a window espag lock in a uPVC window. Window and Door Parts Ireland - How to replace the espag lock on a uPVC window
Another great instructional video brought to you by https://www.windowanddoorparts.ie
In this video i'm going to show you how to replace the espag lock on a uPVC window. This is the same process for nearly all types of window locks, be they roller cams (like in this video), shootbolts or hook locks.
There are a couple of sizes to check to ensure you buy the correct replacement window lock for your window. The first size to check is the backset. This is the measure of how deep the window lock is recessed into the window sash. To measure the backset, measure from the edge of the lock to the centre of the window handle or to the centre of one of the fixing screws. Sometimes the backset will be stamped on the gearbox of the window lock, but not always. The most common backsets are 20mm, 22mm and 25mm.
The next size to measure is the overall length of the window lock. Simply measure from one end of the face plate to the other. Common sizes are 400mm, 600mm, 800mm and 1000mm. These sizes can vary from manufacturer to manufacturer. Some manufacturers stamp the size or a size code on the face plate of the lock. In the lock in this video the size code is "GR.60". This particular lock measures 550mm lock, but is designed to suit a window sash with a minimum size of 600mm. The replacement lock is 600mm long.
The last size to check is the width of the faceplate. 16mm is the standard width. Both window locks in this video are 16mm wide.
The process of replacing the lock is very straight forward.
Remove the two screws holding in the window handle and remove the window handle.
Remove the screws along the face plate of the lock.
Remove the lock
Insert the replacement lock
Insert the window handle and test that the handle is in the correct position in relation to the window lock.
Refit and tighten the two screws for the window handle.
Refit the screws along the face plate of the lock.
The new window lock in the video is slightly different than the old lock. All that's left to do is re position the frame keeps to suit the new lock. This is what you would have to do if you replace a broken lock with a window lock by another manufacturer.
