Select an option for stock status and time to ship


Works with single or double joists up to 3.5" wide

Compatible with all types of decking, including pregrooved or standard lumber, composites, and PVC

Straightens even the most difficult and bowed boards from virtually any angle

Versatile – reversible handle can be used left-handed, right-handed, overhead for putting up siding, or in areas with limited space.

Designed for hardwood; softwood such as pine, cedar, redwood, and others may sustain damage to the side of the board when using.


Even the most crooked boards are no match for the Hardwood Wrench™ Deck Board Straightening tool. In one simple motion, the tool pulls a board into alignment then locks in place, freeing up your hands to fasten the board. It has two knurled joist pins which can be adjusted to accommodate double joists (up to 3-1/2 inches wide), and it can be reversed to work with any deck layout.

This invaluable tool features a solid hardwood handle, stainless steel body and aircraft-grade aluminum that has been hard anodized for ultimate performance. It even comes in a durable canvas carrying case for easy transportation. The Hardwood Wrench™ Tool has a pushing force of about 1100 pounds, and works with all types of hardwood decking to make installation simpler than ever before.
