This fitment system is an innovative product that rolls up and disappears into an aluminum section when opened. And could be easily pulled down and locked at the bottom when mosquito protection is needed. It need not be closed all the time and could be rolled down only when needed. This system employs braking technology that helps the mesh roll up in a slow pace when retracted and doesnt speedily open with a thud at the top. It also employs a self cleaning mechanism that cleans the mesh and the rollers every time the mesh is rolled up and down. This keeps the mechanism from getting jammed due to accumulation of dust.
