From The Anvil Locking Sash Stops

Locking Sash Stops to Restrict Sash Window Opening

A sash stop is fitted to the frame or box and restricts how far a sash window can open. From The Anvil makes secure stops, sold in packs of four, and key-flush sash stops, which retract into the barrel when you want to open the window fully.

From The Anvil describes its lockable stops as insurance compliant and ideal for upper floors, particularly in homes with children. For night-venting, fit the third and fourth stops 100mm above the first two. Strike plates protect the top of the bottom sash. A sash window is usually finished with a fastener on the meeting rails and a pair of sash lifts on the bottom rail, with locking sash stops if you need to restrict opening.

Locking Sash Stops: Questions

How many sash stops do I need?

Secure stops are sold in packs of four, which is enough for two windows. If you want a night-vent position, use all four on one window, fitting the second pair 100mm above the first.

Are sash stops load bearing?

No. From The Anvil states the secure stop is non-load bearing, so it is not subject to the requirements of BS EN 14351-1.
