Multifunctional measurement – The ruler can be used to measure many data points, such as right angles, 45° angles, lengths, depths, and widths. It has an integrated engraver for easy, penless engraving.

Adjustable design – The spring screw and clamping system allow for easy removal and attachment of the stainless steel ruler. The smooth ruler is also excellent for sliding measurements. Versatile applications – This ruler is suitable for measuring, marking, and more for precise measurements. Widely used in residential construction, furniture making, technical information, home building, and other fields. NOTE: For a more accurate right angle, the end of the steel ruler should not touch the ribs (approximately 15 mm gap). src="https://cdn.manomano.com/external-resources/AAHKMJXYDAFdJAOAIMEbOAchMsjc3QZBtjSFHA9dqEpXPSB65XDJrhS VyThNg87jDURivsIQioVkU4HdlEVCOvmJqupLSMDIfZUAQ_v3XTYZwxYwvLYpRNbL-B2xWc_WZQ_hJ6vRmqFJ5Ws6R5UhYuRgW-Rhx2Zn bCq4-u0SjRyGFn-6qzX8UzvOXyg0J0oBdHuGtEYW4-FQ4dEYZVTEpA3j0iYZXHspLBKBxGK2vJKVn_AvY5y69ezeFqcw7ETa69WjcJVF eOdgkl98_SNASV656lQIL8jpcLsHakRra4vQTrvN1JFBxbmdGtmlPqMvU2ho7U8ooG2-tXXy6ov2YFAlRk-wus8V6SgsoQ05a12oiA==" alt="" data-orig-src="https://cdn.manomano.com/external-resources/AAHKMJXYDAFdJAOAIMEbOAchlkWZ0oakZn_uVZ0mPidMNbILvCvspZ4oG3fPgIqc1P05C5SmPDKg0UZdk7akth5Aig0AZrmNXh-Keber1YYQ4UYo5imRU-wWcPgIF2oARBOKdb0_G6rKSPe9eWPbJvsFrzX2E-2yyfEMY__7wieOTLMHUP9t28hPqvkOHD3o2Mw=">"

How to tell if it's a right angle?

Step 1: Draw a vertical line (e.g., the handle on the right) on a white sheet of paper. Step 2: Turn the square over and draw another vertical line above the first vertical line (so that the handle is on the left).
