- Effective sound insulation: Reduces noise and vibrations when opening and closing manhole covers
- Durability: High abrasion resistance and resistance to frost, de-icing salt and aggressive media
- Stability: Prevents slipping or falling out of the chess frame and compensates for unevenness
Further properties
With the HT damping ring, rattling manhole covers are a thing of the past!
The VBT damping ring ensures elastic and sound-absorbing load distribution and absorbs the horizontal thrust, which leads to increased protection of the substructure, frame and cover. This prevents the cover from rattling and increases the service life of the shaft system.
