Specially designed tweezer is ideal for splicing wires faster, easier and cleaner than ever before. A simple one-handed pinch to lock or single thumb-flick to unlock is all it takes for this amazing "third hand" to do its job. Just locate your splice in the center of the 1/2" x 5/8" window and let the tool’s serrated jaws and clever locking mechanism do the rest. Made of solder-resistant stainless steel. Holds stranded and solid wire from #28 to #18. Overall length: 8-1/8".
