Our Metal Grooved or Solid Internal Dowel Tube Connectors, also called Tubular connectors, are not only reliable and resilient, they can also withstand many weather conditions, to suit several tube dimensions.
Grub screws come included in price with our grooved and dowel connectors.
We also sell stainless steel grub screws for these connectors seperately. The size of M8X8 grub screws will fit any of our grooved or dowel connectors.
