This 25mm ramp design high garage threshold kit has been designed to form a watertight seal between the garage door and the floor. The threshold will also prevent leaves, dust and debris from being blown under the garage door, thus ensuring a clean and dry environment.

The ramp design threshold was specifically designed to solve the problem of a sloping floor, causing the gap to vary in height from one end of the garage door to the other. The 'ramp' profile of the threshold allows it to be more tightly fitted to the back of the garage door in such instances, to create a better seal. Please see Additional Information tab below for more information on this.

The kit includes:

  • Threshold barrier
  • Black adhesive (290ml)
  • Fitting instructions


For best results the surface should be smooth and flat and devoid of bumps or troughs.  Remedial action should be undertaken to rectify uneven surfaces prior to fitting the Threshold Seal. 

Tools Required

Tape measure
Pencil or marker pen
Stanley Knife
6mm masonry drill bit
