Contour Transfers

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.

Center-Locating Punches for Curved Surfaces

Locate and mark the centerline on rods, tubes, and pipes, lay out keyways, and establish angles for connections.

Manual locator is for use with a hammer. Gently strike the rod to mark the center.

Spring-loaded locator marks the center with the pull of a trigger.

Pipe Flange Aligners with Protractor

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.

Stepped Pipe Flange Aligner Pins

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.

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.

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.

Pipe Size Rulers

Measure outer diameter and mark lines around pipe. A pipe size conversion chart is printed on these rulers. They’re fiber-reinforced rubber for grease, oil, gasoline, and salt water resistance.
