30 ft. Stud hangers with 1/4” stud attachments are used to hang many different devices from structural beams and supports including, busbars, ladder racks, conduit fixtures, cables, and speakers. They have a load rating of 100 lbs. Garvin Industries’ labor saving Gripple® stud hanger design is seven times faster than competing brands or traditional methods. Their internal “sure lock” release ensures that only the installer is able to adjust length and positioning. Additionally, low material costs and precut lengths prevent scrap on job sites.
