The insulated C-UL-US listed staples meet current standards, are approved for jobsites, and won't crimp or damage the wire. This staple gun features an all chromed steel housing, hardened steel working parts, proven rear-load magazine, and a grooved wire guide and driving blade. Works with 31/64-inch (12mm) insulated fastener and 19/31-inch insulated fastener. Proudly made in the USA.
