Pipe Flange Aligner Pins
Insert a pair of these nut-and-bolt pins into adjacent flange holes and tighten to align flanges before connecting two pipes. One pin in each pair has a level for vertical alignment. Use a separate level to align the flange horizontally. Also known as two-hole pins.
Pins with a 4 ½” length extension let you increase the length of your pins to align thicker flanges. Use the included couplings to connect the extension to your pins.
