Pack of 4 Sash Jammers - Extra Security Locks for UPVC/PVC Window & Doors - White Child Locks - Ideal for Home Secure

I bought these on recommendation from someone else as they had them.When I’m on my own I used to put lots of items in front of the patio doors. With a large bell so if an intruder broke in (they wouldn’t know the items were there as a curtain hid them) I would hear the bell fall.With these jammers I feel very secure and have no need to put anything else there.Certainly recommend them for peace of mind.

The item works well however only 2arrived

Very good quality, nice and firm to turn and installed with ease, that was apart from one, which the hole to screw into the frame was blocked and i had to re drill the hole, however this is relatively minor and was easily remedied.The white caps that cover the screws keep falling out however I am led to believe this is a common problem with most cheaper sash jammers. I have just left them out and they still look ok.Holding up well have had them in a month and so far so good on build and durability.It keeps the little children from unlocking the doors from the inside with the key and escaping, as if someone was determined to get into your property this type of device would do little to stop them other than being a deterrent.Happy purchaser

Great quality and easy fit.Easy to use and feel sturdy and safe.Do what they should for a good price.

Whilst the sash jammers themselves are very good. I think all of they should come with the jack nuts and spacers for fitting. These were perfect for my front door as I didn't need to use spacers or use jack nuts, but my friend's doors which is wider requires the spacers and possibly the jack nuts. But the product itself seems very strong and makes me feel a little more secure in my house when I am alone. I now need to order another set of sash jammers that come with the jack nuts and spacers for my friend's front door.

Good quality and easy to fit

Good value, pleased with purchase

Got these to secure an old porch door where the lock has broken. It is so old we cannot repair the lock and have to replace the whole front of the porch! We cannot afford to do that so these are perfect to keep the door shut without breaking the bank.I got these over others as they had good reviews, I was concerned that they didn't have any spacers like some of the others I had seen, but they did actually come with them so panic over, and after all that we didn't need them anyway! Definitely recommended.
