Fenox Tensioner

The Fenox tensioner allows lifting wires to grow with the vines without loss of tension, and compensates for the expansion of steel wires due to temperature variations.

Consisting of a compensation spring and two galvanized steel hooks (one with an open loop for attaching a wire or chain, and one with a closed loop for attaching to a runner or retaining lugs).

Generally installed on end runners, but can also be installed in the middle of rows (see photos).
