Ruilasago 8X Sash Jammer + Fitting Screws, uPVC PVC Window Door Lock, High Security Arm White (Pack of 8)

Fast delivery, quality product easy to fit, does the job well. Only gripe is one screw missing from a pack but as I didn’t need all jammers not an issue this time. However would happily recommend but check the contents on arrival.

Bought these catch’s for my PVC doors. These are good and easy to fit security catches, which helps as a deterrent. For the price, it is good as an additional security device.

Bought them for our flat so me and my girlfriend have that extra bit of peace of mind when she is home alone and they work fantastic and were easy to install. Can't recommend them enough

Very easy to fit , just give a little more peace of mind

Just what was required as extra security. Good value for money.Well made and good quality.

I used three of Sash Jammer on my uPVC door. Very easy to fit and use. It gives you a very secure feeling night and day. Excellent product.

These locks are great as we had some already. The price we paid on Amazon was a lot cheaper than we paid for original ones & they are exactly the same. Would highly recommend the product & the seller.

Blend in nicely with UPVC frames and doors in conservatory and work well to stop doors from opening from outside. If you have blinds fitted above doors, these may not turn fully into lock position against the frame.
