Performance and stability – the double adapter
High-performance modular adapters play a key role in prosthetic fittings. The lower their weight, the more comfortable the solution is for the user to wear. Using aluminium, with its low net weight, is a trend-setting move. In the revised design, the double adapters can be combined with the 4R57 rotation adapter in particular. The adapters are also approved for a maximum body weight of 136 kg.
