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.
Pipe Flange Aligner Pins with Horizontal Level

Ensure horizontal alignment of pipe flanges with a level rod that runs between two alignment pins. One pin in each pair has a level for vertical alignment. Insert these nut-and-bolt pins into adjacent flange holes and tighten to align flanges before connecting two pipes.
