When deciding on the roof height, remember to allow for the tube being pushed into the ground. We recommend that for cages up to 3’ high you allow at least 8”. For 4’ and above allow 12” - 18”. We do not advise the use of 8' poles as laterals in full height cages, for structural reasons.
The standard lengths supplied are specially prepared for long life and can be individually cut with a hacksaw. Because MainFrame has all year round use and is sold in individual components, it is offers great versatility and value for money. When not in use, just take apart and store in the shed - it takes up very little space.
MainFrame is easy to assemble and dismantle time and time again - without any tools, so your spring vegetable cage can be turned into a runner bean support in the summer in a matter of minutes.
Each tube is manufactured from a light and strong rust-free aluminium alloy. These then lock into joints which are produced from UV stabilised polypropylene making them strong and durable with a degree of flexibility.
