Aluminum Alloy

Secure your hoop house covering against extreme winds with our 6.5 ft Aluminum Lock Channel. Engineered from rust-free, heavy-duty aluminum alloy, this flexible U-channel base securely fastens greenhouse plastic or shade cloth up to 20 mil thick to wood or steel frames. It prevents film tearing during installation and bends smoothly over high tunnel arches for long-lasting, maintenance-free stability. (Spring wiggle wire and mounting screws sold separately).
