Ground wire straightener

Technical data

Product description

The straightener has been designed for straightening steel lightning protection wire, but it can also be used for wires or flat bars made of other materials (e.g. copper or aluminium). Our device is a proven and reliable solution, as confirmed by numerous positive reviews and high ratings of previous versions.

At the beginning of 2024 we decided to refresh our design: the most important change in the new version is the ability to straighten not only round wire but also flat bars with dimensions of 25×3 or 30x4mm! Additionally, compared to the previous model, it is now possible to straighten wires of smaller diameters, starting from just 2 mm. The device has 9 guide rollers – the more rollers, the longer the section over which the wire is straightened, and so the better the results. Two pairs of upper rollers are independently adjustable, and the large butterfly knobs and reinforced pressure screws allow precise adjustment.

Straightening the wire

1) Unscrew the adjusting screws fully so that they do not resist when the wire is inserted.

2) Before inserting the wire into the straightener, straighten its beginning over a length of about 50 cm.

3) Insert the wire between the rollers so that it protrudes about 15 cm beyond the straightener.

4) Tighten the adjusting screws carefully until the wire can be moved using the crank and the wire coming out of the straightener is straight.

5) Use the crank to straighten the required length of wire.
