7/8-1" Thumbscrew Adjuster Assembly

A Tube Adjuster designed to Adjust & Lock Telescopic Tubes, available in a number of different sizes, with a Thumbscrew for crimping the tube in place. These Parts are made from Strong Nylon and have many uses including Clothes Props, Retractable Poles, Wheel Axles and many more applications.  

Although we can offer this part with an Integral Plastic Thread as a special order, the majority of these units come with a Metal Lock Nut inserted, and the unit comes fully assembled with an M8 Thumbscrew. The Metal Nut has an added advantage in that you can replace the Thumbscrew with a Metal Threaded Handwheel, without having to worry about a plastic thread getting stripped!  

As with all our Tubular Products, we list them exactly as you would buy the tube so it's Outside Tube Dimension x Wall Thickness / Gauge Size. We show standard colours & finishes where possible but these are constantly changing so if you require a colour not listed in the drop-down, speak to us as we may well have added it since.

Had product a number of times really good product and service however courier not good on this ocasion still not received goods

Response from BPF Websales
Sorry to hear about the issue the carrier had with that last delivery (w/o 312213) but quickly looking at it, I see that you used CV35 9SB for the delivery postcode but that would appear to be the postcode for your invoice address, as google is indicating CV34 6TH is what should have been used? As soon as that sort of thing happens, it gets kicked out of their automated systems which does cause delays, so if you've still not had the delivery - a quick call to UPS customer service to correct that postcode, should sort it.

These are very hard to source components (Only company I know who sells them) For my own use I needed a 1 1 unit that could be clamped anywhere on a 1 column ... so I had to use a sanding drum on a Dremel to file out the excess 18 inch on all units. Great fun

Q: I am after the 1" to 7/8" connector but must have the metal nut insert appose to the internal plastic thread. Can you confirm if I was to order these, that's what I would get?

A: Hello. These do have a Metal nut insert, as you can now see in the images we have added to the gallery. I hope this assists. Kind regards, BPF
