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.
