Setup Blocks & Spacers for Woodworking, Decking & Fencing – 1/16" to 3/4"

This set of spacers (setup blocks) takes the guesswork out of spacing boards, panels, and workpieces. Each set includes 14 precision spacers — two of every size from 1/16" up to 3/4" — plus a dedicated holder to keep them organized.

What makes these different: each spacer has a removable slotted tab that lets it hang directly between two boards while you work. Slide it in, let it hold the gap on its own, and keep both hands free for clamping, fastening, or aligning.

Included sizes:

• 1/16"
• 1/8"
• 1/4"
• 3/8"
• 1/2"
• 5/8"
• 3/4"

(Two of each size, 14 spacers total, plus the holder.)

Great for:

• Deck board and fence picket spacing
• Cabinet face frames and shelving reveals
• Paneling gaps
• Tile and general project spacing where consistency matters

Why woodworkers love this set:

• Hands-free hanging design — the slotted tab lets the spacer hold itself in the gap
• Full range of common sizes in one set, from 1/16" to 3/4"
• Durable 3D printed construction built to handle daily shop and jobsite use
• Includes a holder so spacers stay together and are easy to grab
