ET Block with Shims Qty: 1 Specifications: Alternate Alloy options AS NEEDED (see alloy options below) Block has four (4) notches that are 0.012” wide and at depths of 0.010”, 0.020”, 0.040” and 0.060”. These dimensions are stamped on the block. Actual dimensions may vary +/-0.002”. The block nominal dimensions are 0.25” T x 1” wide x 6” long The block has a total of eight (8) shims attached to it by a stainless chain. There are four (4) aluminum shims · (2) at 0.005” T · (1) at 0.015” T · (1) at 0.025” T There are four (4) plastic shims · (2) at 0.005” T · (1) at 0.015” T · (1) at 0.025” T The shims are color coded, 0.005” Blue, 0.015” Pink and 0.025” White. This information is stamped on the bottom of the block. The shim thickness range combination allows for 0.005” to 0.050” per material at 0.005” T intervals. · Additional shims can be added for more thickness.
