Reach a variety of spots with the confidence that your extension won’t disengage. Also known as positive-locking extensions, these extensions hold sockets in place with a ball that only retracts when you pull the collar down. They lock to your socket more securely than other extensions. Use them only with hand-drive tools.

Lock your socket into these extensions to prevent accidental disengagement. Also known as positive-locking extensions, they have a ball that secures your socket and only retracts when you pull the collar back. This creates a stronger hold than standard extensions. Use them with hand-drive tools only.

Bend these socket extensions around obstructions to turn hard-to-reach fasteners. They’re best for light duty adjustments because they can’t apply as much torque as standard socket extensions. Use them with hand-drive tools only.

Lock your socket into the extension to prevent accidental disengagement. Locked in place by a ball that retracts when the collar is pulled (also called positive locking), these sockets hold more securely than our standard extensions. These extensions are thicker than standard extensions, and also have enough give to flex under high force without breaking. This makes them a good choice for use with impact tools.

Reach a variety of spots by keeping common extension lengths on hand. To withstand the high torque and force of impact tools without fracturing, these extensions are thicker and flex more than extensions for manual drivers.

3/4" and 1" square drive extensions require a retaining ring when used with impact tools that have a hole- or ring-and-hole style socket retainer. They work without a retaining ring when used with impact wrenches that have a pin-style socket retainer.

Also known as positive-locking extensions, these extensions hold sockets in place with a ball that only retracts when you pull the collar down. Designed to prevent accidental detachment, they lock to your socket more securely than other extensions. They’re thicker and less brittle than manual extensions, so they withstand the high torque and force of impact tools. They flex slightly when force is applied, so they’re less likely to break. Each set includes three common extension lengths to tackle a variety of jobs.
