The slotless joiner is used to link standard 220mm straight ducting with itself or any of the other 220mm components; with which it provides a smooth & strong joint. Typical other fittings are: horizontal or vertical elbows, cross connectors, tees, etc.; which require a joiner at each interface. The slotless joiner incorporates three metal spring brackets, which securely grip with the flat face of the mating 220mm duct components. This ensures that a positive, permanent connection is achieved. The slotless joiner is easily and simply locked or released by turning the locking slot through 90 degrees; using either a coin or wide bladed screwdriver.
