Security and ease of use are paramount in a Harol garage door: from protecting your fingertips to securing your personal possessions. That is why every sectional door is fitted with the key security mechanisms as standard. For example, your garage door has a SKG bend as standard, making it less easy for burglars to squeeze the wheel out of the bend.

  • Obstacle detection

    The door always moves up and down safely by means of a motor or photocell.

  • Finger safety

    The unique design makes it impossible to trap your fingers between two panels.

  • Spring break device

    The door does not drop if the spring breaks.

  • Optional SKG security kit

    Economical kit that offers three minutes extra resistance to burglary attempts with simple tools (resistance class 2 approval mark - WK2).

A colour to satisfy every desire

There are over 7 billion people on the Earth, most of whom have their own individual taste. So if you are thinking of buying a garage door, it is only logical that we should try to satisfy those varied expressions of style at home.

With over 300 colours in the Harol range, this poses no problem, and all RAL colours and various textured coatings are included in the basic price. The latter are also scratch-resistant and very low-maintenance. You can also choose a PVC film to achieve a perfect match with the look of your windows and doors.
