Easy to install and easy to use. Simple and effective.

Fitted easily
Arrived and was east to install on my front door as I only have a single mortice lock my grandson Can reach and open. Now feel safe knowing my 3 year old grandson can’t get out the front door.
User
Great lock, don’t use the screws
DO NOT USE THE SUPPLIED SCREWS. THEY ARE TOO SOFT and you will strip the heads.Really happy with the lock and easy installation process but save yourself a headache and buy some better screws. The metal is so soft, the heads strip easily and you’ll end up having to unscrew it with pliers (if you’re lucky)
User

Good product but poor quality screws
Good product, only thing wrong was all 3 of the long screws all snapped when fitted even with my pre drilled pilot holes, nightmare now having to remove the lock and install it further up with stinger screws and now have to fill the original hole i chiselled out to fit it, great thanks for that !

Perfect Security Door Blocker
This is the second Defender Door Blocker we bought,very strong ,virtually impossible to break open the lock from outside,easy to install,screws comes along with the pack.As this gives additional security for the door,its highly recommended,moreover there is no need to drill any holes on the door for installing this blocker as this is fitted to the door frame.Very good product.
