HRT Safety Holds All Grips II Holds
Описание товара на английском языке:
All HRT holds have a metal string wrapped around the hole in the hold. If the hold breaks, the pieces stay together hanging on the metal string. In fact, the broken hold cannot fall down unless the hold is unscrewed.
According to Finite Element Analysis models and ISO 130 strength tests performed by HRT, hold strength increases by up to as much as 300 percent. By spreading the internal stresses in the hold more evenly around the bolt hole, the UBI technology decreases the pressure at the bottom and spreads it to the sides of the hold, making HRT holds stronger than ever.
