The wire line winders can be used with any size wire or cord (when making guying kits for example).
These line winders are made from a black nylon material reinforced with fiberglass fill.
They are exceptionally strong yet lightweight.
The series of 3 holes in a row are used for tightening guy lines – just one pull and it cinches right up!
The wings have slots to capture the wire when you want to quickly add or remove turns to adjust the frequency.
