The H-23NP is a chrome plated single joint with antistatic properties (ESD) used to assemble the HJ-23NP joint set.
This piece is a different version of the H-13NP that can be assembled on an AP-HINGE bracket to create a swivel 90-degree angle. Without the hinge, the H-23 can't be assembled on 28 mm pipes. Make sure you have enough AP-HINGE in inventory when you choose this piece.
