Item: 30 cm
Framing a room where the walls weren't square to each other. Grabbed this ruler, laid it in each corner, and had every angle I needed to cut the studs. No guessing, no math.

Item: 40 cm
The 45° stop is dead accurate and the bigger 40cm size means I can check angles on wider boards without resetting. Aluminum is light enough I don't notice carrying it.

Item: 30 cm
Metalworking layout — I need both 90 and 45 and the ability to read off custom angles. This ruler does all three without switching tools.

Item: 40 cm
Solid ruler and the 90° stop holds tight. The scale graduations are fine enough for layout work. Would give 5 stars but the numbers are a bit small for my eyes in dim light.

Trim carpentry where every angle matters. The positive stops mean you're not trying to eyeball 45 or 90 — you feel it click in and you know you're right.

Item: 40 cm
Drywall hanging on tapered walls. Used this to find the slope in each direction and was able to cut sheets without a second trip for bad fits. Anti-slip grips are real.

Item: 30 cm
Cabinet installation where doors need to be set perfectly. Checked each corner with this, adjusted the hinges, and doors hang square. Worth every penny.

Good accuracy and the weight is reasonable. The anti-slip coating works well. Took a moment to learn which scale to read for custom angles but the instructions helped.

Description
Mark it square without marking it wrong
90° and 45° stops, plus any angle you can measure.
One ruler handles every layout problem — no calculation, no second-guessing.
90° & 45° positive stops
Variable angle graduations
Aluminum & steel build
Anti-slip design
90° and 45° stops lock in place instantly
Two positive mechanical stops — one at 90°, one at 45° — mean you feel them click in and you know the angle is right. No eyeballing, no drift during measurement.
For any other angle, the graduated scale gives you a precise read straight off the ruler.

Aluminum and steel — light but tough
Aluminum alloy keeps the weight down so the ruler doesn't tire your arm during a long layout day. Stainless steel edges stay sharp and accurate without rust.
The anti-slip design grips the material so the ruler stays in place while you mark — you're not fighting it to stay where you put it.

Portable enough to carry all day
Compact design means it fits in a tool bag, a truck door pocket, or a pouch on your belt. Lightweight enough that it's part of your routine, not a burden.
Whether you're marking trim on a kitchen remodel or laying out angles on a steel fabrication job, grab it and go.

Three angles, one tool
1. 90° for squaring
Press the stop into the corner or edge. Feel it lock in — you're at 90°. Mark straight across.
2. 45° for angles
Flip to the 45° stop for chamfers, bevels and roof slopes. Click in and mark.
3. Custom angles
Use the graduated scale to read any angle in between. Lay the ruler across the angle and read the graduation.
Frequently asked questions
What is a combination square used for?
Layout and marking: squaring edges at 90°, marking bevels and chamfers at 45°, and reading any angle in between. Carpenters, metalworkers and site layout crews use them constantly.
How accurate are the stops?
The 90° and 45° positive stops lock in place precisely — they are accurate enough for trim work, framing and layout where the stop is the measurement itself.
Does the anti-slip design really work?
Yes. The ruler grips the material so it doesn't slide while you're marking. You can mark with one hand without the ruler wandering.
Which size — 30 cm or 40 cm — do I need?
30 cm is portable and fast for most marking work. 40 cm is better for wider boards and gives a wider reference base for checking angles on larger surfaces.
Is the ruler rust-proof?
Stainless steel edges resist rust, and the aluminum body won't corrode, so it survives damp workshops and job sites without maintenance.
Can I use it with a pencil and a knife?
Yes — mark with a pencil for layout, or score with a knife or marking gauge along the edge. The edge is straight and the stops are rigid so the line stays true.
