The SG13TE secure grip bolt-hole spreader can be used on all flange types with bolt-hole sizes ranging from 1.49" (38mm) to 1.92" (49mm). The collet holders are supplied with adjustable drive cones which can be adjusted outward from their central position allowing the tool to spread flanges apart and remove a spacer, wafer, or butterfly valve. This mid-end, hydraulic model offers up to 14.6 imperial tons (130 kN) of spreading force. Spreading force of 29.2 imperial tons (260 kN) if used in pairs as recommended. Short Collet Holder Sets (SCH) are available which can offer an improved range of application. Collet Holders can also be dismantled and inserted through bolt-holes from the opposite side.
