Last refreshed Sep 7, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A genuinely useful profile-tracing tool for flooring and trim work, mislabeled as a ruler in this catalog; buy it for shape duplication, not for measuring.

Overview
A connectable contour gauge with 5-inch and 10-inch sections of locking pins that press onto an object's edge and hold its profile, for tracing irregular shapes onto flooring, tile or trim rather than for linear measuring despite its ruler category placement.
Listed under rulers, but the title and spec copy describe a profile duplicator, not a straightedge: rows of sliding pins lock onto a shape and let you transfer it to another material. The connectable design is the real differentiator, since most contour gauges ship as one fixed length.
- 5-inch and 10-inch connectable sections
- 0.05-inch locking pin blades
- Screwdriver-adjustable pin tension
- Dual inch and centimeter reference scale
Who it's for
Useful for flooring and tile installers, trim carpenters and anyone scribing pipe surrounds or baseboard against an uneven wall. Not a substitute for an actual ruler if what you need is a plain measuring straightedge.
Pros and cons
- Connects to three spans, 5, 10 or 15 inches
- Locking pins hold the traced profile
- Adjustable pin tension
- Printed inch and centimeter scale for reference
- Not an actual measuring ruler
- Thin pins can bend under heavy pressure
Performance notes
Rows of thin pins, 0.05 inches thick, slide against the object and lock in place to hold the traced shape. The 5-inch and 10-inch sections connect end to end for a 15-inch span on wider profiles, and pin tension is adjustable with a screwdriver so the gauge holds its shape until you transfer it.

Frequently asked questions
Is the JOREST contour gauge the same as a ruler?
No, despite being listed under rulers it is a profile duplicator with locking pins that trace an object's shape rather than a straightedge for measuring.
Can the two sections be used separately?
Yes, the 5-inch and 10-inch sections work on their own or connect together for a 15-inch span.
What is it used for?
It is used to trace irregular shapes, such as molding profiles, pipe surrounds or uneven wall edges, so the outline can be transferred to flooring, tile or trim material.
