There are three types of cord guide

Cord guide K3, is for installation in the top corner of the frame. It fits most windows of wood, PVCu, aluminium or composite. The design allows easy installation to the window frame requiring only two-screw fixing.

Cord guide K4, takes the operating cord down in front of the glass. This means that only the uppermost part of the glazing bead has to be cut. This guide is particularly suitable for fixed-frame windows and sliding doors.

Cord guide K24 with gearing is recommended for large blind units or where frequent raising and lowering is expected.
