Our Wind Bracing upgrade kit adds strength and rigidity to your Caterpillar Tunnel allowing it to withstand greater wind speeds. When paired with our Wiggle Wire upgrade kit, you also have the ability to eliminate the cone-shaped plastic bunching at each end of your tunnel. This can be helpful with installations where space is limited.
The Wind Bracing upgrade kit includes four, 12’ solid purlins (shipped in eight, 6’ sections) that should be installed at roughly 45° angles between the bottom of the third bow, and about 4’ high on the end bow. (see photo)
