Normal tank belt would lengthen when it gets wet in the water, this often leads the trouble of tank displacement at the time of traveling on the surface of water and or getting out of water.
The " bio- tank lock pro" will maintain the maximum tension of 100kg or higher in holding the tank with assist of the built-in spring. For this reason, even when the belt gets wet with water, the built-in spring will absorb the belt lengthening, thus it will not cause the tank displacement.
