4 way cross black connector set

(1 customer review)


  • HJ-3 is a 4 way black painted metal joint set that consists of (x2) H-2K, (x1) H-4, (x3) M6-25B bolts and (x3) M6-N nuts
  • Often used in the center of structures the HJ-3 allows you to create a four-way 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
  • All our Joint sets are made of steel with E-coated paint which not only is environmentally friendlier, it also creates 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.
