The Punchdown Tool is a versatile tool suitable for use with 110 cross-connects or reversible termination blocks. It can be used with the punch feature alone or by reversing the blade for combined punch-cutting action. The impact level is fully adjustable, allowing the user to use as much or as little force as needed. The tool is constructed of sturdy plastic for long-term use from one job site to another, and the compact body makes it easy to store or carry in a tool box, tool bag, or pocket. The spring-loaded design of the Punchdown Tool provides fast, low-effort wire seating and termination, while the internal impact mechanism eliminates jamming for longer, trouble-free service life. The tool inserts wire into the block for a corrosion-resistant connection and trims off excess for an easy one-step punchdown termination. It is a universal-type tool that uses standard twist and lock blades for terminations. The Punchdown Tool stores spare blades in the handle, so no additional carrying bags or tubes are needed on the job site. The replacement blades for the tool are made of high-carbon tool steel, heat-treated, and precision-ground for long life. They are reversible blades for seating/cut or seating only for jumper wires and have a rust-resistant finish to ensure years of use. The Punchdown Tool has clear labeling on the cutting side to reduce costly punching errors. The tool measures 5-3/4 inches in length, 1-1/2 inches in width, and 1-1/8 inches in depth, and weighs 0.5 lbs. Replacement blades for the tool come in two types - 66-Style and 110-Style - and measure 2-1/4 inches in length, 1/2 inch in diameter, and weigh 0.1 lbs.
