DODOWIN Connectable Contour Gauge, 5- and 10-Inch Sections, Inch and Metric Scales

Connect the 5-inch and 10-inch sections to trace profiles up to 15 inches, or use either gauge on its own. This flexible setup helps transfer the shape of an edge or obstruction to your workpiece, whether you’re fitting tile around a corner or marking a longer flooring cut. Inch and centimetre scales also make quick reference checks convenient.

Fit and sizing

Choose the 5-inch section for smaller corners and compact profiles, or reach for the 10-inch section when you need more coverage. Join them to make a 15-inch gauge for tracing larger contours. Using the right section for the shape at hand keeps the tool practical for both small detail work and broader cuts, without relying on a single fixed-length gauge.

The gauge is designed to copy irregular shapes and edges, including winding pipes, circular frames and ducts. Press it against the profile you need to reproduce, then use the copied outline to guide marking for your project. Its dual scale shows inches and centimetres, making it useful for tracing as well as quick measurement checks.

Where it shines

For tile, laminate and carpet fitting, the gauge can help capture the outline around pipes, corners and other shaped edges before you mark a cut. In woodworking, trim and carpentry projects, it transfers contours to the material so you can work from the shape rather than estimate it by eye. The same approach is useful for molding and other DIY tasks where a straight measurement alone does not describe the edge.

The ABS plastic body has a lock to hold a copied profile, and its tightness can be adjusted with a screwdriver. That lets you set the feel for the tracing task and keep the tool ready for repeated use. Buyers commonly describe the gauge as easy to use and practical, and appreciate the side measurements for quick checks. Feedback on adjustability is mixed, so the adjustment mechanism may feel different from one user to another.

Practical questions

Can the gauge be used in more than one size? Yes. Use the 5-inch or 10-inch section alone, or connect them to make a 15-inch gauge for a larger profile.

What kinds of shapes can it copy? It is designed for irregular edges and profiles such as pipes, circular frames and ducts, and can help with marking for tile, laminate, carpet, trim and woodworking projects.

How do you adjust the gauge? The tightness is adjustable with a screwdriver. To use the sections together, connect the 5-inch and 10-inch gauges.

When it makes sense

Choose this DODOWIN gauge when your project involves transferring shaped edges to a material, from a small corner detail to a broader outline. Its separate and connectable sections make it useful across different profile sizes, while the lock and dual measurement scales support marking and quick checks during fitting, flooring, carpentry and DIY work.
