Gantry blocks are a means to raise a gantry for a CNC Router off of the table. They are designed to offer a rigid connection point and give 7″ of clearance between the table and bottom of the gantry. We have 2 styles, A and B. For Maximum rigidity in both directions, it is recommended that both styles be used in an alternating fashion.
Each riser block comes with 7 Drop In T-Studs and nuts to mount it to a 3030 piece on top and either a 3030 piece or 2 1530 pieces on the bottom.
