Hangermate is an all-steel threaded fastening system for overhead vertical suspension of threaded steel rod in pipe hanging, fire protection, electrical conduit, and cable tray applications. They are available in versions that can be installed into a variety of base materials, including steel purlins, beams and bar joists, wood frame columns and beams, as well as concrete ceilings, beams, and columns. 1/4" and 3/8" diameter threaded steel rods can be suspended vertically with Hangermate (a 1/2" diameter size is also available for wood). They are also offered in a side-mount style for lateral installation of 1/4" and 3/8" diameter threaded steel rod to joists, columns, and overhead members. For all steel and wood hangers, a Hangermate socket driver is recommended to allow proper installation with a self-drilling screw gun. For concrete hangers, a power impact tool with a clutch is recommended. A swivel-head version is also available for flexible connection angle and positioning of rod hangers. An acoustic ceiling eyelet version is also available for suspending wire or cable fixtures.
