HDSM-X Spring Joist Hanger

Joist or wall hanger with metal coil spring. Springs can react quickly enough to absorb impact and can also absorb low frequency noise. They can be fitted with a ceiling channel clamp or eye bolt. HDSM-X hangers consist of a side attachment steel angle gusseted on each side to prevent bending. The hanger incorporates a steel spring, which can gain circa 25mm of deflection, reaching a natural frequency of 3-5Hz. Housing configurations offered for simple attachment to 1.5″ x .5″ channels or 12 gauge wire. The hanger range is available with different spring ratings to suit different ceiling weights. The load capacity ranges from 10kg up to 59kg. They feature a neoprene cup, required to absorb high frequency noise. This extends through the hanger box which ensures that the hanger rod does not contact the hanger box.
