What are window sash locks?

Quadrant Sash Window Lock

These come in various different materials so you will have the ability to choose which style will fit in with your home décor.

Quadrant sash locks are simple and relatively small, so if you are looking for a subtle way to improve your window security then these could be the ones for you.

 

Brighton Sash Window Lock Fasteners

Much like the Quadrant Sash Window Lock these attach to both the window frame and casement. However, where they differ is that the Brighton’s use a screw mechanism, which does make them more secure. The Brighton’s also come as locking and non-locking varieties. They are slightly chunkier than the Quadrant sash locks, so do your research to make sure they will go with your window and décor style.

 

Fitch Fasteners

These use a semi-circular plate that pivots to keep your window securely closed. The fitch fasteners are a very traditional way to secure your windows, but are relatively small, so won’t be a huge feature of your window. They also come in locking and non-locking versions.

  • Claw fasteners
  • This traditional Victorian window lock uses a cam action to swing a curved metal claw into a receiver, stopping your window from being opened.

How do you lock a sash window?

The way you lock a sash window depends on what type of lock you have installed. However, the general idea is that make sure the window frame can be moved easily within the casement before latching the frames together. You would then latch the frames together using and screw locks or stops that you have had installed.

 

Sash Window Stops

Sash stops are installed on the upper sash, this stops the sashes from sliding over each other. This prevents the window from being opened. They come in two parts, a receiver that you screw to the inside of the window frame and the steel barrel that will fit inside the receiver. Once you have drilled the correct size hole into the frame and have screwed in the receiver, the barrel will then screw into the receiver when it’s in use. You can choose from 2 types of sash window locks for sash stops. You can choose protruding bolts that can be removed with a key, or you can pick bolts that are extracted.

A good set of sash window stops will vary in price, but on average you can expect them to be around £10.

 

Sash Window Dual Screws

Sash window screws offer added security for those are security conscious and will fit most sash windows. This type of lock will bolt through the top and the bottom of the sash to stop your window from opening. The dual screws will stop anyone from being able to slide open your window, even if the main fastener is broken or has been tampered with.
