Enerpac Mechanical Flange Spreader

The SG6TM secure grip bolt-hole spreader can be used on all flange types with bolt-hole sizes ranging from 0.94" (24mm) to 1.18" (30mm). 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 low-to mid-end, mechanical model offers up to 6.7 imperial tons (60 kN) of spreading force. Spreading force of 13.4 imperial tons (120 kN) if used in pairs as recommended.
