The ladies frames were developed with the aim of minimizing weight. To achieve this, lightweight beams were used as support frames with minimalist aluminum joints. The two inner beams form a fixed unit with the damper, while the outer beams can be attached to the inner beams for transport. This allows the frame to fit completely into a keyboard bag. The resonance tubes made of PVC or 3D-printed material simply hang in straps inside the frame.

The ITEM frame from the suitcase frame, which has already been optimized in terms of weight, is used as the base frame.
