Our Wind Bracing upgrade kit adds strength and rigidity to your Caterpillar Tunnel — allowing it to withstand stronger winds. 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 — or where traditional, vertical endwalls are desired.
The Wind Bracing upgrade kit includes all necessary hardware, plus four, 12’ solid purlins (shipped in eight 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)
