Hardwood Wrench™ Deck Board Straightener


We hear it all the time; “I wish I had THAT last week!” It never gets old to see the amazement and hear the delight builders have when they first see the DeckWise® Hardwood Wrench™ in action. They grab it and raise it upward in the air, as if it were a Knight's sword. They sense its hefty toughness and straight away want to use it on a project. It's thrilling to observe!

Why the excitement when builders get a grasp of our hardwood board straightening tool? The reality is that, bending warped hardwood boards into place is done with a chisel. This is the primary method in the building industry. It's a practice that gets handed down from builder to builder and generation to generation. It's not wrong per se, just more of an old-school method.

Ipe Clip® Installation

When hardwood installers consider how back-breaking it is to battle unwieldy hardwood boards, they appreciate the ease of use our Hardwood Wrench™ offers them. Besides, when installers see our wrench also includes a locking cam which permits them to let go of the wrench handle while installing fasteners, they immediately know they won’t need a knee propped up in order to hold the tool from slipping. They understand the Hardwood Wrench™ stays in place and will not pop off the board, such as other wrenches often do.

This is when we hear installers ask, “Where can I get me one of these wrenches?”

The Hardwood Wrench is a must for any deck builder! We have used it on Standard decking and Hardwood with great success. This tool puts the others to shame when it comes to strength and ease of use. I have purchased numerous inferior tools in the past that just wear down; but the Hardwood Wrench is with me for the long haul.Vincent Monteforte (W.Kingston, Rhode Island)
I had a nightmare deck project and was working alone with a pile of bowed wood. My neighbor saw my frustration and handed me his Hardwood Wrench . Amazed that such a tool actually existed I managed to get back on track and completed the job in half the time. The only bad part about the tool was when I had to give it back!Steve Whitehead (Groton, Connecticut)
I have two words Strong & Simple! This tool makes my projects painless! I’m just a one man operation so the Hardwood Wrench serves as my crew.Pete Meadows (Rugby, North Dakota)
