Centre Purlin Kit
$185.00 – $320.00 AUD excl gst
Complete Centre Purlin Galvabond Tube Steel Kit
Our Centre Purlin upgrade kit dramatically increases your Caterpillar Tunnel’s ability to withstand wind and heavy rain/hail loads, increasing overall strength and rigidity, and turning it into a true four-season structure.
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, cross connectors and hardware, and TEK screws to attach the purlin together. (see details below)
Note: While the purlin will increase rigidity, it will also increase the time and effort involved in moving the tunnel.
