Our rope closure hamper bags are designed with a nylon draw cord sewn in the top of the bag and brought through a grommet for added strength. All seams are safety-serged for maximum durability and set-in bottoms increase capacity up to 40%. Our plastic rope lock helps keep bags from slipping off the stand while it also helps prevent spilling of soiled linen during transport. Sizes shown indicate the open diameter of the bag; bags will fit over round, triangular or folding hamper stands.
