Extension Blocks feature 28 mm holes with inch spacing. They are ideally suited as table extensions or for joining multiple tables together for long projects. Extension Blocks are hardened.

Extension Blocks 20″ and longer in length have leg mounting holes, and all blocks over 20″ in length should be supported by legs when used as a table extension.

SAFETY NOTE: Extension Blocks should only be joined to the table using connector bolts. Do not use fast clamping bolts or other available bolts to join.
