The joiner is used to connect standard 300mm straight ducting with itself or any of the other 300mm duct components, with which it provides a smooth & strong joint. Typical other fittings are horizontal or vertical elbows, cross connectors, tees, etc., which require a standard joiner at each interface.
Note: A 300mm slotless joiner is also available (Part No: TC1279-287A).
