The door cannot be secured properly – and at night there is an unpleasant feeling.

Whether in a hotel room, in a rented apartment, or at home: Those who have no control over their own door sleep restlessly. The FortiGuard doorstop secures any standard door in seconds – simply slide it under, lock it in place, done. The robust zinc alloy withstands where cheap plastic alternatives give way. The result: real peace, no matter where you are sleeping.

Benefits

  • No more restless sleep due to unsecured doors: Those who slide the FortiGuard under the door no longer have to worry about whether the door will open during the night – whether traveling or at home.
  • No long searching for tools or assembly instructions: Tightening and securing takes only a few seconds – without a drill, without instructions, without prior knowledge.
  • No more worries about whether the protection will hold in an emergency: The construction made of solid zinc alloy does not give way under heavy pressure – unlike cheap plastic wedges that break under the first force.

Specifications

  • Material: Zinc alloy
  • Weight: 350 g
  • Dimensions: 12 x 9.3 cm
  • Color: Red
  • Variants: Standard version, Alarm version
  • Delivery content: 1 piece

Application

  1. Position: Slide the FortiGuard into the lower door gap with your foot until it fits snugly.
  2. Secure: Press the adjustable foot against the floor and secure the position – no tools required.
  3. Release in an emergency: Simply lift and pull away – it can be done in a few seconds even under stress.

Pro tip: Lightly moisten the rubber foot on smooth surfaces (laminate, tiles) – this noticeably increases the grip and the stopper stays even firmer in place.
