SurePromise 4PCS Sash Jammers Home Security Locks for uPVC Windows & Doors Locks Lockings

I wanted these to sit between my 2 patio doors, (attach to one and lock on to the other)Unfortunately these are not deep enough, and can't get over the raised lip between the 2 doors. I have ended up using 4. 2 at the top and bottom of each door. Required a bit of fiddling, but they fit and work. Adds that extra level of protection and well worth the money.If someone wanted to use excessive force to get in your home, these won't stop them, but it will certainly slow them down.These will do the job against the sneaky bar steward thieves though....

I have these everywhere, along with other locks, love theseadded to existing security measures, let's just say I live in fort knocks 😁

Absolutely love this product and have them on all windows and doors for extra security. Ones on doors serve an extra purpose of being a child lock, placed high up on door, we turn them as entering the house so the little ones can’t open doors and get out by themselves.

These are great for extra security for doors and patio doors.Easy to fit.

Easy to fit

Excellent

A little bigger than expected and some of the blanking pieces wouldn't fit over the screws. Other than that easy to fit and work well.

Good for windows but not strong enough
