Saker Aluminum T-Square Ruler with Protractor 0–48 cm (18") – Laser-Engraved Scales, Adjustable Scriber

Made for tradespeople, designers and hobbyists who need consistent, repeatable marks, this tool combines a 0–48 cm (0–18 in) ruler with a multi-angle protractor in a single lightweight aluminum body. It arrives with a red mechanical pencil and eight refills so you can start marking immediately. The durable construction, engraved markings and adjustable locking nut make it a compact, reliable option for cabinetry, framing, drafting and general shop layout work.

How accurate are the measurements and markings?

The Saker T-square uses laser-engraved scales for clean, long-lasting numerals and tick marks that resist wear. The ruler reads both metric and imperial units up to 48 cm / 18 inches while the protractor dial shows clear angle graduations for repeatable layout.

• Laser-engraved numbers and ticks for improved legibility
• Dual metric/imperial scale for cross-system projects
• Rigid aluminum alloy resists bending for consistent readings

What makes the angle finder and scribing feature useful?

This tool’s adjustable protractor includes a locking nut so you can capture and transfer angles quickly. Combined with the scriber functionality, it lets you mark bevels, radial lines and assembly layouts without swapping tools.

• Multi-angle scribing by loosening the nut and repositioning the blade
• Locking mechanism secures the chosen angle for repeated marking
• Works directly on stock for layout, bevel setting and radial marks

Is the ruler durable and comfortable to use on the job?

The main body is cast from aluminum alloy to balance low weight with abrasion resistance so it keeps its straightness under normal shop use. Its slim profile and integrated scale make it easy to clamp, carry in a tool roll or use alongside squares and clamps while working.

• Aluminum alloy construction reduces deformation and wear
• Compact T‑square shape fits in a toolbox or apron pocket
• Included mechanical pencil and refills provide immediate usability

How does it speed up layout and drawing tasks?

By combining ruler, protractor and scribe in one, this tool removes handoffs between separate instruments and cuts layout time. You can measure length, set angles and mark directly from the same device, which helps maintain alignment and repeatability on multiple parts.

• One-hand angle setting and line drawing reduces repositioning errors
• Integrated pencil holder keeps the marking point aligned with the scale
• Saves time when transferring angles across several workpieces

Who is this for? Saker’s aluminum T-square and adjustable protractor is aimed at carpenters, woodworkers, furniture makers, architects, model builders and DIY enthusiasts who need a compact, accurate layout tool. It’s useful for anyone doing repetitive angle transfers, small-format drafting or precision joinery who prefers a lightweight, all-in-one measuring and marking solution.
