Buying guide: Tensioners: match the size to the wire, not to the row
Hardware is the smallest line on a trellis invoice and the one that decides whether the row can be retensioned in year five without pulling the whole thing apart. These are the parts that join wire to post, wire to wire, and wire to tension.
An in-line tensioner takes up slack anywhere along a run, which means a sagging span can be corrected without cutting the wire out and starting again. Size follows the wire diameter: size S covers 1.3 to 2.5 mm, size M covers 2.2 to 3.5 mm and size L covers 3.0 to 5.0 mm, and the large size also works with a release pin so a row can be slackened deliberately.
Packing is to your specification, so tensioners can arrive bagged by size, boxed by the hundred, or loose for repacking at your end. The tensioning tool is sold separately and works with both cam-type and screw-type tensioners.
Hangers and chains carry the load at the post
An end-post hanger is what the wire actually pulls against, so it has to suit both the post section and the wire. Our hangers are wire-formed on our own machines in a range of lengths and diameters, which means the hook opening and the leg length can follow your post rather than being fixed by a catalogue.
Chain is used where a run needs a fixed anchor point, a short adjustable link, or a repair to a damaged section. It is supplied cut to length, and because we form it in-house the link size can match the load rather than the nearest stock size.
Custom wire parts are the reason to talk to a factory
AD clips, hangers, chains and similar wire parts can be made to a drawing or a sample. Our wire-forming machines are our own, so a new shape is a tooling question rather than a sourcing question, and the same drawing can be repeated on later orders without drifting.
Send the drawing with the material and the coating you want. If there is a cheaper equivalent that does the same job, we will say so, because a part that is over-specified is a part your customer pays too much for every season.
Common questions
Which tensioner size do we need?
Size S covers 1.3 to 2.5 mm wire, size M covers 2.2 to 3.5 mm and size L covers 3.0 to 5.0 mm. Pick by the wire diameter in the row, not by the row length.
Will your tensioners work with the tools we already own?
Our tensioning tool works with both cam-type and screw-type tensioners, so a mixed inventory can be tensioned with one tool. If you already run a specific system, tell us which and we will confirm compatibility before you order.
Can hangers be made for our post section?
Yes. Hangers are wire-formed on our own machines, so hook opening, leg length and wire diameter follow your post and your wire rather than a fixed stock size.
Do you make parts from our drawing?
Yes, from a drawing or a sample, including AD clips, hangers, chains and similar wire forms. Coating and material are specified with the drawing.
How is hardware packed?
To your specification. Common formats are bags by size, boxes by the hundred, or loose for repacking, and the packing is quoted with the price.
