The Equalizer™ SWi Innovative Range of Flange Spreading Wedges have been developed to assist in the spreading of all flange joint types with a minimum access gap of 6.0 mm (0.25 in). The tools can be used during pipework construction, commissioning or routine maintenance.

The SWi Innovative Range of Flange Spreaders have fewer moving parts and no finger pinch points. The tools have been developed to increase the spreading distance on each step while gaining easier access between any remaining stud-bolts within the flange joint. The tools provide a much higher spreading force to the existing SW flange spreading tools. The SWi tools are supplied with a swivel handle, safety lanyard and stepped block attachment as standard.
