  • HJ-2K is a black painted metal corner joint set that consists of (x1) H-2, (x1) H-3K, (x2) M6-25B bolts and (x2) M6-N nuts
  • Commonly used for corners the HJ-2K creates a three-pipe intersection when combined with our 28mm pipes with just a 5 mm Allen key
  • This is an ideal choice when making tables and any cube-like structure
  • E-coated paint for a lasting finish that will stand up to outdoor environments
  • Don’t forget all our joint sets are 100% Re-tinkable!
  • Fits on 3/4″ EMT conduits with the use of a EMT-ADPTR34 for every connection. Select the option to automatically add them to your purchase.

    A bit tricky to use at first (all three pipes need to be in place to tighten/position), but once you get the hang of it, this is a very versatile piece.
