Diamond trellis panels are constructed using a good quality planed batten, that is framed all round with a rebated frame. As with all Bendrey Brothers trellis, these panels are pressure treated (green), so the colour will match the other pressure treated timber we keep in stock. Ideal for use with climbing plants. Hole size is approx. 50mm x 50mm. The measurements are shown in the format: Width x Height (middle of curve) / Height (edge of curve).
