Hangermate® is an all steel threaded fastening system for suspending steel threaded rod vertically overhead in pipe hanging, fire protection, electrical conduit and cable-tray applications. They are available in versions which can be installed in a variety of base materials including steel purlins, bar joists and beams, wood frame columns and beams, as well as concrete ceilings, beams and columns. Steel threaded rods in 1/4 and 3/8 in diameters can be vertically suspended with Hangermate® (a 1/2 in Dia size is also available for wood). They are also offered in a side mount style for lateral installation of 1/4 and 3/8 in Dia steel threaded rods onto joists, columns and overhead members. For all steel and wood hangers, a Hangermate® socket driver is recommended to provide proper installation with a drill screw gun. For concrete hangers, a powered impact tool with a clutch is recommended. A pivot head version is also available for flexible connection angle and positioning of rod hangers. An acoustical ceiling eyelet version is also available for hanging wire or cable attachments.
