Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned. Once two sets of holes are aligned, you'll know the rest of the holes are as well. Made of durable chrome-plated steel, they'll hold their shape over time and resist rust.

Probes take the shape of a pipe joint so you can transfer the exact outline to the pipe before you cut.

Line up two pipe flanges and determine pipe angle with the included nut-and-bolt pins, level, and protractor. Flange holes align as you tighten the pins.

Transfer contours, patterns, and shapes for applications such as fitting floor tile and installing pipe insulation. A series of narrow probes slide within a frame to duplicate any shape.

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.
