The W82 casement fastener is a time-served window latch made by one of the major lock manufacturers in the UK. The design of this fastener incorporates a night vent latch position and the latch itself is key lockable. The key lock within the handle works slightly differently to most in that when the latch is closed the handle locks requiring the key to release. No chance of forgetting to lock the window with these but we would advise you to take care with windows that you may designate for fire-escape. In that case you need a non-locking handle. This Era locking casement fastener is suitable for timber or wood windows and comes with a special packer piece which will fit under the catch peg to sit the catch correctly on an angled frame. The handle can be installed onto weather-sealed windows or non weather-sealed windows and is supplied with a full set of instructions to help you install the fastener correctly.
