Product Description 20-Piece Deck Board Spacer Jigs are a great addition to your deck building toolbox. No more guesswork of using nails for spacing. Now, with the rainbow color-coded design, finding the right spacer is easier. The blade + rounded corner design prevents denting or marring of decking boards when installing boards. No matter you are a pro contractor installer or a novice, building a deck with ideal gap sizes between deck boards is essential. Drainage and drying on any deck is important and determined by gap size. Choose a proper spacer to make consistent spacing and beautiful decking finish. For every 24 inches of board length, just insert 2 or more spacers as many as deck fasteners are installed. To remove the spacers, just lift up with the integrated handle in a breeze. 5 sizes of deck spacing: Red 1/8" (3.2mm), Orange 5/32" (4mm), Yellow 13/64" (5.2mm), Green 1/4" (6.4mm), Blue 5/16" (8mm).
