I just finished a 14x16' cedar deck working alone and this tool was a great help in securing the proper spacing. Provided the 3rd hand I needed using the Camo hidden fastener system on 16' 5/4 decking. Let me put the boards just where I needed them for proper spacing. There is a bit of a learning curve knowing where to place the BoWrench to lock it place. Took me @ 4 boards before I placed it consistently. Saved me a lot of work once I got the hang of it.
