A Crop Bar set is used for hanging baskets and climbing plants, and also acts as an additional ridge wind brace. The smaller polytunnels widths have a vertical brace. The larger polytunnel widths have two diagonal braces
The maximum Crop bar sets you can have is the number of hoops your polytunnel kit has, less the two end hoops. For example, polytunnel kit with 6 hoops can have a maximum of 4 Crop Bar sets. This calculator allows you to calculate the maximum number.
Steel Accessories bought without a polytunnel kit will be subject to a freight delivery charge which cannot be calculated automatically. Please contact us for this charge.
