The Defender secures your roller shutter door by trapping the door mounted bracket between the floor plate and the Defender which in turn prevents the door from being lifted. The Defender itself 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, stopping anyone from tampering with these fixings. The Defender itself slides and locks into position using 2 bayonet style fittings on the underside of the Defender. Once in place our bullet lock prevents the Defender from being removed, locking it into position. The lock and housing are fully protected internally of the Defender making it incredibly grinder resistant.

The rear cowl is fully welded and 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 defender easily into position. The Defender can be locked and unlocked in a matter of seconds.

The Defender is fully powder coated and floor base plate is made from stainless steel to withstand 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 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.
