Spring Hanger Boxes are used for support of suspended low frequency equipment and pipework to effectively isolate vibration. They have a wide range of applications including fan coil units, attenuators, ducting, exhaust, package units and piping. The vibratrol D Series can be used in-line with threaded rod for single and trapeze type systems.

Vibratrol springs are made in Australia by a QS-9000 and IS09002 certified company, complying with the relevant Australian Standards, zinc plated for protection against corrosion and heat treated to ensure consistent performance characteristics.

The D-Series Spring Hanger Box is the perfect heavy-duty solution to your vibration issues, with spring capacity options rated up to 100kg. The capacity can be further increased with a booster spring, adding an additional 50kg to the weight rating. Its practical design includes a large diameter spring for stability, centred threaded rod support and wide hole opening, allowing for some angular requirements.


  • Colour coded springs for load identification. Great with multiple services running side by side. 
  • Updated with the new v-cup to insure sturdy placement and centralised threaded rod location.
