Main use

RoHS

Ideal for installation of small equipment as it can be used while placed: Anti-vibration rubber KN does not need to be fixed to the floor and can be used while being placed, making it suitable for installing small equipment.

Performance/Features

1. Good anti-vibration and soundproof effect

The spring constant is smaller than that of Anti-vibration rubber of the same shape, so a better anti-vibration and sound insulation effect can be obtained.

2. Good installation stability

The contact surface with the floor has a unique pattern and has a structure with good installation stability.

3. Use as is

No anchor bolts are required, and it can be used as is, making it easy to change layouts.

4. Uses special rubber that does not stain the floor
