125mm round plastic duct 90° elbow. Good durable product and a snug taper push-fit into the standard 125mm (internal diameter) plastic solid duct.The slight taper on the elbow ends grips the duct securely meaning that additional duct tape might not be required.But in an inaccessible invisible place where leaking condensation drips might cause damage I usually add a wrap of tape anyway, just in case age and de-plasticizing or vibration might slacken the grip.This is ideal for use inside a building and protected from the UV of bright sunshine.

Pros:Good quality plastic with a clean white finish -easy installation - arrives quickFast delivery every time I’ve ordered — reliable for project timelinesFits standard 150mm ducting perfectlyCons:None so far — has always arrived in good condition and does the jobI’ll continue buying this for future projects. It’s dependable, easy to work with, and arrives quickly — all important when managing client work.
