Hook-Mounted Pleated Blind
Hook-mounted pleated blind installation — the rail hangs on the glazing bead with hooks. Glass-balcony fit and measurement details.
How Does the Hook Work?
In the hooked system there are metal or composite hooks on the top rail's back face. The blind is hung on the top edge of the bead surrounding the glass. No screw, no tape, no drilling. The blind's own weight locks the hook to the bead.
The connection point is not the joinery profile but the bead. This distinction matters. The bead is the thin profile framing the glass and the hook sits on its top edge. Nothing bonds to the joinery surface, nothing is drilled.
The Hooked Connection's Natural Area
In three scenarios hooked mounting is unrivalled. All for the same reason. The blind moves together with the glass.
Folding Glass Balcony
The blind hung on the glass sash folds together with it when the sash folds. It works while the balcony is open too.
Opening Window Sash
The blind is bound to the sash, not the joinery. When the window opens the blind turns with the sash.
Frequent Take-Off Need
At cleaning or moving the blind comes down in a second. No tool, screw or tape residue.
Measurement and Hook Details
Bead top-edge measurement
The bead width the hook will sit on is measured. No problem on standard beads, on special thin beads a check is needed.
Number of hooks
By the blind width two or more hooks are used. The load distributes evenly.
Glass–bead relation
The hook enters the gap between the bead and the glass. The gasket stiffness makes a difference in the mounting feel.
Where Are Its Limits?
The hooked connection requires a bead. It does not work on a beadless glass surface (fixed glass partition, directly plastered glass). On very wide and heavy units the hook's carrying limit exists. As the width grows a screw or bracket connection becomes the more correct choice.
In glass-balcony systems the bead profile changes by model. On some thin-profiled systems the hook seating is different. A photo of the joinery or balcony system is enough to clarify the suitability.
Hook Size and Sash Behaviour
The hook depth is taken by the profile thickness. Different hook sizes are provided with the product and fitted by the joinery's top-profile measurement. A wrong-size hook either stands loose or does not seat. The profile thickness is the data that must be reported at measurement.
In a tilt opening the hooked unit's behaviour must be known. When the sash opens inward the unit tilts together with the sash. The tension cords hold the fabric on the joinery plane and the blind does not sag. This behaviour is part of the hooked system's design.
Points to Mind While Fitting the Hook
The hook must seat fully onto the profile edge. A half-passed hook slips at the first sash movement and the unit tilts. Once fitted, the hook's gripping of the profile top is verified by touch.
The two hooks' alignment on the rail matters. Hooks not on the same line hold the rail diagonally and the fabric gathers to one side. The hook seats on the rail are marked in production. The alignment stays by those marks.
The hook is metal and can scratch the profile surface. The hook's contact face is plastic-coated but dragging the hook across during fitting scratches the profile. The hook is passed at a right angle and seats into place.
On a glass balcony the extra check is the folding test. After the units are fitted the sashes are folded fully and it is verified that the blinds do not hit each other. The hook size of the hitting unit is changed.
