Aluminium greenhouse clip

Small clips to hold bubble wrap insulation or shade fabric to aluminium framed greenhouses with screw channels in the aluminium bars.

I have intentionally made the washers slightly tight to install to the clips so that they can be pre-installed without having them fall off in my pocket.

Hole included in the clip to potentially use them for string to support plants but I have no idea how much weight they are likely to be able to take!!
