The bag can be refolded facility on the rubber and it covers completely the inside and the outside of the ring for protection during the work to maintain cleanliness. The blocking systems guarantees the fixing and prevents the sliding of the bag during the use. The rubber is injected on the ring support and creates a unique and compact structure.
