Balance isolation system
The Balance isolation system consist of four isolation units that has been integrated in the bottom and top of a shelf. Each units consist of seven removable springs. A user can maximize his isolation shelf performance by removing the amount of springs in order to optimize the vibration isolation for the equipment pending the weight and its distribution over the top shelf surface in order for the equipment to be perfectly leveled. With all seven springs mounted the shelf can uphold a weight of 45kg. If further weight is needed to supported heavy equipments is an HD (High Density) spring available as an accessory and then if all seven springs are exchange on all four units (28 springs), the isolation shelf can uphold as much as 100kg. On all Balance isolation shelves is a bubble level integrated to make it easy for the user to keep his system leveled.
