An extendable handle for a drywall tool having a pair of telescoping tubes that are reversibly locked in place relative to each other by a locking assembly comprising a lever, a pin and a yoke that are mounted on a base positioned on a first tube. The pin is actuated by the lever and engages an opening on the second tube to lock the tubes in place. The pin and lever are spaced apart circumferentially on the handle and are connected by the yoke. The yoke is received in a slot in the base and does not extend beyond the surface of base during operation of the lever. |
