Am i right in saying the O Dia of both ends is 103mm dia. Could you tell me what the inside dia is.** A: Hi Rodger,The 103mm refers to the height of the bend, the spigot size is 99mm external - male fittingthe internal size of the spigot is 97mmLength (mm) 136Width (mm) 136Height (mm) 103Spigot size (mm) 99Colour White **Q: What glue should i use** A: I did not ise glue as I screwed the coil into a connection for my dryer. **Q: Hi. i have an 4" inline extractor and a big horn 11401 dust hood for 4" duct hose. can i connect them with this product? thanks.** A: Hello, yes I have connected the elbow to my extractor fan and the other end to the hose. Having viewed the dust hood I have noticed that you would need to also purchase either a 4 inch / 100mm Round Back-draught Shutter / Ducting Connector with Non-Return Damper Flap or a 4 inch / 100mm Round Ducting Connector - Pipe Connector Joint this would be for the hose to connect onto the big horn 11401 dust hood. Lastly or a complete sealed unit using jubilee clips. Hope this answers your question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality ducting *by on Reviewed in the United Kingdom 10 August 2026* Bought before, always good quality product. ### ⭐⭐⭐⭐⭐ Good quality plastic with a clean white finish -easy installation - arrives quick *by on Reviewed in the United Kingdom 25 June 2025* 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.
