The Defender secures your roller shutter door by trapping the door mounted bracket between the Garage Defender floor plate and the Defender itself which in turn prevents the door from being lifted. The Defender also stops the door from being pulled outwards and the roller shutter slats from being ripped out of the track on either side of the door frame.

The floor plate sits just 10mm from the floor leaving no bulky trip hazards. It is secured into the floor using 3 M8 bolted sleeve anchors which are located on the inside of the garage, behind the door, stopping anyone from tampering with the fixings. The Defender itself slides and locks into position using 2 bayonet style fittings on the underside of the Defender. Once in place the bullet lock prevents the Defender from being removed, locking it into position. The lock and housing are fully protected internally of the Defender and the distance from the Defender outer skin to inner lock is greater than the width of a grinder disc, therefore making it grinder attack resistant.

The rear cowl sits flat up against the garage door, preventing it from being opened. The top plate covers the bullet lock preventing attack by a drill on the bullet lock and also acts as a large handle to move the Garage Defender easily into position. The Defender can be locked and unlocked in a matter of seconds.

The Garage Defender is fully powder coated both internally and externally. It is the same for the Defender floor base plate which helps oppose the elements. The Defender has been designed and is manufactured here in the UK and comes with a 10 year guarantee.

We also offer a Garage Defender for an up and over garage door.


If you own a Guardsman garage security barrier already, or you plan to purchase one in the future, we can use the same key to operate both your Defender and Guardsman garage security barrier.

Reduce the stress and have a security system operated on a single key.

The Garage Defender is installed using 3 sleeve anchors with countersunk bolts. All three fixings fall within the garage so cannot be tampered from the outside. There is also a door bracket that is secured to the roller shutter door. This is what is trapped within the Garage Defender and stops the roller shutter door from being forcefully lifted and opened.
The Garage Defender physically stops the garage roller shutter door from being opened by trapping the door bracket within the Garage Defender, situated at floor level.
No, the Garage Defender door bracket will not interfere with the door as it is rolled up as the door bracket sits just 80mm from the bottom slat.
The Garage Defender is locked in place using a bullet lock, the same bullet lock as used on our Guardsman garage security barrier. This locking pin is 16mm in diameter.
Yes, both our Garage Defender and Guardsman garage security barrier can be locked using the same barrel lock and therefore the same key making your life easier and hassle free.

Garage Defender for up and over door

Good design with all ground fixings hidden from view. Instructions are clear and easy to follow. Installed unit myself. installation service is available if required. Solid deterrent protecting a vulnerable point.

Simon Watson
Top lock

I noticed the Defender had excellent reviews, also the fixings for the lock are under the garage door and inside the garage itself. Where as some of the locks on the market have fixings in front of the garage door and therefore too close to the edge of my concrete base. The whole lock seems to be well made and balanced when lifting by the handle. I’m very satisfied with my purchase. Thank you.

Eric Burt
Excellent product just what I was looking for

Looked high and low for a solid British made product didn’t want anything with a padlock and looked at the quality reviews of other products and performance nothing touched the The defender made designed and made in Britain. When product arrived was amazed at the design and quality the fitting was easy if you are a diy doer. Thumbs up to Image 4

Steve Shaw
Excellent products

First class products, and service, clean and tidy, very professional from start to finish. I would highly recommend

Fergus Dalgarno

When I bought the Garage Defender the instructions advised that I needed intermediate skills to fit it. I have to say that fitting the Garage Defender was possibly the easiest DIY job I have done in the last 5 years. I would recommend these to anyone. An excellent, well made and designed security tool.
