Klein Tools KT223X4-INS Lineman's Insulating 4-in-1 Box Wrench – 1000V Rated

Overview

The Klein Tools KT223X4-INS Lineman's Insulating 4-in-1 Box Wrench is crafted for professionals who value safety without sacrificing efficiency. It stands out as the only double-ended 4-in-1 wrench that meets the ASTM 1505-10 standard for a 1000V rating. A transparent, see-through handle lets you quickly verify that the metal ends remain isolated, a small but meaningful cue on busy job sites where panels and conduits demand careful handling.

Versatile, all-in-one design

Four 12-point socket sizes are integrated into a single tool: 1/2, 9/16, 5/8, and 3/4 inch. Packed into one compact tool, this wrench minimizes handoffs and gear swaps, helping you move smoothly through panels, meters, and service entrances where space is tight and timing matters.

• Four sockets in one tool reduce clutter and search time
• See-through insulation confirms isolation without guesswork
• Reverse ratcheting action on both ends speeds adjustments
• Enclosed gear mechanisms protect against dirt and debris
• 48-tooth count delivers a shorter swing arc for tight spaces
• Larger pawl is operable with gloves for easier switching

Designed for field reliability

Built to endure demanding daily use, this wrench reflects Klein Tools’ commitment to quality and precision. The company’s nearly two-century history translates into tools that feel dependable from the first grip to the last turn. With the see-through handle and robust construction, users can focus on the task rather than the tool, knowing the design supports careful, confident work near live electrical components.

• Solid, durable construction designed for professional tasks
• American-made heritage with six generations of engineering know-how
• Transparent handle adds a quick, visual safety check
