I ordered 3 sets of 2-4-6 blocks. The reasonable price with the addition of the free set of 1-2-3 blocks made me decide to take a chance on ordering these as I have not ordered from Travers previously. We use these for set-up of parts to be measured on a CMM. I found the blocks to be within the stated 0.0003" tolerance. I will definitely consider Travers for future purchases for my Metrology Lab.
