Tired of not being able to reach that tricky bolt? This 4-piece extension bar set is here to save the day! It's for 1/2-inch drive sockets (the big, tough ones), and it comes with four super useful lengths: 3 inches, 5 inches, 8 inches, and 10 inches. That gives you the perfect reach for almost any job under the hood or on your project. They're made from tough steel and have a nice chrome plating to resist rust and look good in your toolbox. The brand is ATE, and the model/number is 50277. They're brand new, non-magnetic (handy for certain situations), and come with a 1-month manufacturer's warranty. The system is Standard (SAE). Just snap your socket onto one end and your ratchet or breaker bar onto the other. It's a simple, must-have set for any serious DIYer or professional mechanic. Makes life so much easier when you need that extra few inches of leverage or clearance. A solid, no-nonsense addition to your tool collection.
