Fitting a sash window press bolt
The security bolts and locks you use for a sash window are different in design to those used for a casement or hinged window. Common designs include the screw lock or screw bolt, which is effectively a bar that is inserted through both sashes holding them together. A second common option is provided by press bolts, and the technique for fitting a sash window press bolt is shown below.
1. Press bolts consist of a lock body and a receiving plate. They are locked by pressing the bolt in place, and unlocked with a key. | |
2. With the window in a closed position, place the lock body flush with the edge of the inner frame. Mark and drill pilot holes. | |
3. Position the receiving plate on the outer frame, flush with the edge to engage directly with the lock body. Mark, and drill pilot holes. | |
4. Secure the body and receiving plate. The lock is simply operated by pressing the bolt in place when you wish to lock the window. | |
5. To release the bolt, you must use the key provided by the manufacturer to allow the bolt to spring back into an open position. |
Window lock tips
- For the best security, sash locks are generally fitted in pairs with one close to either side of the window.
