DNHS – High Capacity Spring and Low Dynamic Stiffness (LDS) Rubber Hanger available in a variety of sizes and load capacities.
The DNHS series of hangers features both a metal spring and a Low Dynamic Stiffness (LDS) rubber element. This provides acoustic isolation against both low and high frequency vibration. Springs can react quickly enough to absorb impact and can also absorb low frequency noise. This isolates against low frequency noise such as that from footfalls. The LDS rubber element isolates against higher frequency noise such as that from airborne vibration. The metal spring can be selected from a wide range to suit the particular acoustic and ceiling weight requirements. The load capacity ranges from 5kg up to 5325kg for multiple spring variants.
All springs have additonal travel to solid equal to 50% of rated deflection
