Each 'clamp' is supplied as a flat piece of aluminium measuring 4" (10cm). The aluminium is flexible enough to allow you to bend the 'clamp' to suit your requirements whilst retaining its shape.

Use the 7/16" (11mm) cropped head bolts & nuts supplied to fit through the holes of the 'clamp' & slot into the glazing bars of an aluminium greenhouse - for wooden greenhouses substitute the bolts & nuts with washers & woodscrews (not supplied).

Supplied as a pack of 10.
