Self-locking wrench makes it easier to straighten and install crooked deck boards, even by yourself

/ Each

Powerful deck board-straightening tool lets you tackle and install crooked boards by yourself. The versatile Hardwood Wrench™ is designed to provide more bending power and handle all types of decking, including grooved or standard lumber, composite or PVC boards. 

The Hardwood Wrench easily locks into place for one-person operations. The versatile tool is designed to handle many situations. It expands to fit single or double joists up to 3.5 inches wide.

The reversible handle means you can straighten bowed boards from nearly any angle—left or right—even in a limited space. Its knurled knobs let you grip framing when there isn’t enough clearance to use standard joist pins.
