Corner Tube Support


In a nutshell....

Corner brackets used to join timber and hold support tubing for mini polytunnel cloche kits. The bracket is a right angle which is screwed to 2in x 2in timber to make the corner, 25mm tube slots tightly into the bracket to form the ribs of the tunnel.

These corner brackets are part of our sturdy DIY mini polytunnel kit. The kit consists of brackets, connectors and tubing which enables you to build any size (within reason!) tunnel you like. Tunnels can be covered with a range of protective materials like polythene, fleece, bird netting or insect protection mesh to build a warming mini greenhouse or a crop protection cloche system.

Mini tunnels can be attached to raised beds or fixed directly to the ground with our ground securing peg kit. Tunnels can be easily moved around the garden to give plants a protective nursery environment before being moved on to the next crop. Covers are also interchangeable meaning you can use a polycover to warm the ground in the Spring while a mesh can be used on the same frame to protect from cabbage root fly later in the season.

For more detail watch our mini polytunnel video by clicking the red tab on the top left of the photo.

Measurements:  Please note the internal dimensions of these supports are 25mm and the external 39mm

Very happy with mini tunnels, I've bought two now. The only grumble I have is the cross connectors. The circumference is slightly wider on one axis. Don't understand why this should be as the tubing is one size. Tubing is very difficult to push on, needs a bit of brute force on the wider connectors, whereas it's fine on the other axis.

Fantastic video I will be ordering a couple of these mini tunnels. I have found that if you use a bowl of hot water at the ready to dip the ends in the tubes fit better in the brackets
