Dry Erase Magnetic Protractor

Designed for fast, precise angle work in drafting, carpentry, tiling, and classroom projects, this Dry Erase Magnetic Protractor is a versatile tool built to streamline angle measurements. The dry-erase surface lets you annotate measurements, cutting angles, or layout marks directly on the tool, then wipe clean in seconds for reuse. The magnetic backing keeps it securely positioned on ferrous surfaces, so you can work with both hands free and without slips.

Key features that save time and boost accuracy

• Magnetic backing: Adheres to metal whiteboards, filing cabinets, tool chests, and steel surfaces for stable, hands-free use.
• Dry-erase surface: Mark angles, run-out notes, or cut lines and erase cleanly after every pass.
• Clear 180-degree arc: Bold, high-contrast numbers and tick marks for quick readings even from a distance.
• Durable construction: Lightweight, impact-resistant plastic that holds up to busy shop environments.
• Compact portability: Slim profile fits in kit bags, drawers, and lab desks without crowding your workspace.

Who this is for

Ideal for woodworkers, metal fabricators, tilers, interior designers, and students learning drafting and geometry. If you frequently lay out angles for cuts, bevels, or mitre joints, this tool reduces repetitive marking and misreads, helping you finish projects faster with fewer errors.

Practical usage ideas

• Layout bevels on trim or crown molding by marking the angle on the dry-erase surface, positioning the protractor on your workpiece, then transferring the line directly to your cut.
• Draft quick sketches on a whiteboard or metal surface; use the protractor to check degrees during brainstorming sessions or classroom activities.
• Combine with a compass or ruler for accurate circles and arcs in tile layouts or metalwork.

Care and maintenance

Wipe with a dry cloth or a mild cleaner suitable for dry-erase surfaces. Return the protractor to a metal surface to re-secure its position when needed. Avoid abrasive cleaners that could scratch the surface.
