Distance Pieces for Adjusting Vertical Daylight

Distance Pieces are high-strength spacer blocks used to quickly and safely adjust the vertical daylight in concrete cube and cylinder compression testing machines. Correct daylight adjustment supports axial-fidelity load transfer, allows the piston to operate within its optimal stroke range, and ensures repeatable contact conditions for each test. Chamfered-edge geometry prevents damage to specimens and platens; surface coating provides corrosion resistance and maintains dimensional stability under heavy laboratory use. Modular height options enable quick setup during transitions between multiple specimen types. The wide-base form ensures full contact with loading platens. The design is compatible with automatically controlled hydraulic test frames, allowing tool-free quick changes when used together with test heads and intermediate adapters.
