The Black Heavyduty Mudwire is the big brother of the Green Standard Mudwire general-use wire. The handles are made with a durable polymer & are shaped to give you a comfortable ergonomic grip without having to wrap the wire around your fingers. The Heavy Mudwire is made with a thicker high grade stainless steel braided cable, making it stronger & more resistant to kinking. The Heavy wire is built to take on the big jobs.
