This is the product that started Production Lapping. In 1963 the Space Block was designed to be used in the shop area as an accurate means of measuring and setting “stops” on machine tools. The blocks range from .050 – 1.00 in length while being held to a tolerance of +/- .00005. Many “Off-Shore” manufacturers have copied these blocks, but Production Lapping’s Space Blocks are still the original and still the best! |
