For use with the Kreg K4 and K3* Jig, these blocks are great for quick and easy repair work.
Each spacer compensates for 1/4'' in material thickness. Simply add the blocks to
the bottom of the Jig’s Drill Guide. Use one block for 3/4'' material, 2 for 1'' material
and 3 for 1-1/4'' material. Includes 3 blocks.
*Please note: For use with Kreg K3 jigs purchased after January 1st, 2009 with slots on the underside of the drill guide.
