A minimum insertion gap of 0.39" (10 mm) is needed which expands up to 2.02" (51.5 mm). Retraction force is supplied by the single-acting spring return cylinder. The maximum operating pressure is (10000 psi 700 bar). The included SB2 stepped safety block provides reassuring support, and can also be used to increase the lifting height to 2.72" (69 mm).
