More About The W53 Locking Casement Fastener
This stylish and popular locking casement fastener meets the home insurance requirements for key locking and is available from stock for next working day delivery if ordered before 3:00pm. With a range of colours that compliment most modern decors you won’t be disappointed with this versatile locking window fastener. The key pattern is the same throughout the model and also the locking stay W54 negating the need to hold individual keys. Suitable for timber windows of most designs, even narrow ones, this locking window latch comes with a night vent facility to allow a two position locked opening. The gap is only small but allows a trickle flow of air if needed.

Material: Zinc die cast.
How To Fix The W53 Locking Casement Fastener:
Offer the assembled catch and fastener up to the window corner and mark the fastener fixing hole positions with a sharp point or a pencil. Fix the locking window fastener to the opener and then re-position the catch to the latch for marking out the position for fixing on the fixed frame. Generally speaking the fixings need to be 13mm centres from the corner of the window each way.
Before purchasing remember these points:
- Used on timber/wood casement windows only.
- Can be used on top opening or side opening casement windows.
- Weatherseals between the opener and the fixed frame are not recommended for this handle. Where gaskets/weatherseals have been used this can cause premature failure of the handle.
- Handles can become looser through use. This is perfectly normal.
