The TriLink Saw Chain Saw Chain Grease Gun has a reloadable cartridge that can be easily refilled with all-purpose grease for many years of use without having to replace the tool. A well-oiled chain enables it to run smoothly around the bar nose with low friction thereby reducing heat and chain stretch. The saw chain grease gun is compatible for all chainsaws that have a sprocket nose guide bar, regardless of the length or brand of the chainsaw. The chainsaw grease gun has a high impact plastic body with steel nose and heavy duty spring. This saw chain grease gun is light weight and durable for ease of use in the field. In addition, the saw chain grease gun keeps the chain and bar lubricated for smooth cutting.
