The Mechanical Secure-Grip Flange Spreader, specifically the SG6TM model, is a versatile tool designed to be used on various flange types. It is capable of spreading flanges apart and removing spacers, wafers, or butterfly valves. The tool is equipped with collet holders that have adjustable drive cones, allowing for easy adjustment and positioning.

The bolt-hole sizes suitable for this flange spreader range from 0.94″ (24mm) to 1.18″ (30mm). It offers a spreading force of up to 6.7 imperial tons (60 kN). However, it is recommended to use the tool in pairs for optimal performance, which increases the spreading force to 13.4 imperial tons (120 kN).
