I had a plumber install my kitchen faucet and he had a tool that I had never seen before that could easily tighten locknuts in small spaces. It looked like a smaller version of those gadgets that pros use to unscrew a light bulb in high ceilings without the benefit of a ladder. It was about a foot long, red casing and you insert different parts for different chores. Its not the old long metal with a semi-circle gadget to turn a nut, left or right…those are awkward..Anyone know what it is actually called? I went to lowes and the help there is pathetic to say the least.
