The HushKarts are designed for quiet mobility with rubber-cushioned 4-inch sealed bearing casters. Designed for convenient storage, each HushKart offers three shelves with slip resistant surfaces and raised edges. Ideal for use as surgical case carts, and for use by pharmacy, respiratory and CSD. Designed for easy cleaning, its cart-washer washable. The one-piece, double-wall polyethylene construction (no creaking bolts and no rattling metal) will not rust, corrode, dent or peel. One-piece seamless construction eliminates hard-to-clean grooves and crevices. Available in three colors, establish a color-coding system to fit your needs. Choose a color (slate blue, dark brown, coffee beige) to coordinate with the décor.
