Measuring up correctly for angle bracket installation

For models 11-8110, 11-8120, 11-8220, 11-8222, 11-8320 and 11-8370

For this type of installation the angle brackets are screwed directly onto the window sash. Using the fitting parts, the pleated blind is then fixed to the brackets.

Ordering measurements:

Ordering width  = glazing bead measurement + desired overhang
Ordering height = glazing bead measurement + desired overhang


Please note:

in order as far as possible to prevent any light getting in at the sides, the pleated blind should overhang to the left and right of the pane by at least 15 mm – 20 mm if possible. When measuring up, please ensure that the finished pleated blind will not hide the window grip or any other fittings important for its use.

How to measure the glazing bead

To determine the glazing bead dimension, measure the clear height and width of the window glass (including the rubber seal). To account for any window tolerances, always measure the width in several places.

Sloped glazing bead

Where the glazing bead is sloped, measure the width as tightly as possible to the pane, inclusive of the seal.

Straight (rectangular) glazing bead

Where the glazing bead is straight, measure the width from fold to fold.

Angle bracket installation is recommended for:

  • Plastic windows
  • Wooden windows
  • Aluminium windows
