This wire tensioner can be used for vines and wire fences. It is reinforced with 1.5mm thickness. This wire tensioner allows you to tie, with the ideal clamping tool, line wires into the posts or fences. You only have to place one at the end of each end of the steel wire, insert it into the hole of the screw, pull it with force and then rotate it to tighten perfectly the line. It is made from galvanised steel to provide the product with a professional strength and a long service life. Thanks to its mechanism, you can tie the line wires in an efficient, easy and reliable way.
