Additionally required: Cross Connectors

Often purchased with

We know of at least one Cocoon Tunnel  fitted with a centre purlin that withstood a metre of snow like a ‘champ’ (Although we don’t recommend trying this at your farm!)

Each kit includes purlins, joiner sleeves, purlin end saddle kits and Tek screws. Cross Connector pairs are sold seperately, you will need one pair for each hoop excluding end hoops (end hoops use the purlin saddle kit).

Note: While the purlin will increase rigidity, it will also increase the time and effort involved in moving the tunnel.
