The Mini-Reel has a strong latch which allows the excess twine to be stored on the reel while tensioning the twine or wire on the temporary electric fence. It uses a lynch pin that allows the spool to be replaced in less than a minute without tools. The low cost and compact size makes this reel ideal for trail rides, garden and shrub pest control fence and short grazing fences. Many other uses are possible from kite string to speaker wire. A well designed reel, handy for shorter lengths. Comes pre-loaded with 660' of polywire containing 6 stainless steel conductors.
