Some models for HSW do not perfectly fit into the HSW cells, thereby being loose and slide out under load. However, changing the whole model to enhance the fit is time-consuming.
This adapter addresses the above issue by providing a better fit and extending the weight distribution to two cells. Simply glue in your loose HSW component into the adapter and press it into the wall.
The author remixed this model.
I doubled the small adapter to obtain a 2x1 adapter, which increases stability
