Kapro Squares

A square is a measurement device consisting of two straightedges set at right angles to each other. The “square” refers to the tool’s primary use of measuring the accuracy of a right angle (90°) so you want to make sure your angles are 90° certified. In within this category there are many variations.

305 Framing Square Certified 90° heavy duty painted steel frame with complete conversion and rafter tables printed on the reverse side


A large carpenter’s square, also known as a steel square is graduated with scales typically for use in cutting off and notching and some carpenters say that it holds the answers to common roof framing problems. There are 2 main parts to the square, the body and the tongue and they intersect at the heel on the outside edge of the square. On the framing square there are rafter tables and a brace measurement table.

444 Ergocast™ Rafter Square Certified 90°, durable and lightweight with molded-in conversion tables and easy to read gradations.


This square is also known as a speed square, rafter angle square and triangle square. Basically, the rafter square is a triangular tool that combines functions of the try square, combination square and the framing square. Rafter squares can be made of metal or ABS. Degree gradations embedded on the tool eliminate complex trigonometry calculations, helping you speed up the job. Beyond making basic measurements or marking lines on dimensional lumber, it’s also used as a saw guide for short 45° and 90° cuts and other perpendicular cut marks, angles for roofs, stairways and decks.

317 Adjustable T-Square 120cm (48″) The 317 has a sliding head that adjusts to any angle and ABS end caps with ledge for a hands-free hold, an indentation in the profile to mark and cut safely, highly visible dual directional printed scale, etched angle markings on the T-head and folds for easy storage.


A T-square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table, drafting board, drywall or wooden surfaces. It may also guide a set square to draw vertical or diagonal lines. The T-square has two components: the long shaft called the blade and the short shaft called the stock or head. A drywall T-square is designed to cut drywall or other plasterboards.

325 Magnetic Lock Combination Square A Kapro innovation, this square has a magnetic lock adjustment that will amaze you. Instead of screwing and unscrewing every time you need to change the measurement, just pull it out and re-position it.


A combination square is a multi-purpose measuring instrument primarily used for:

  • Ensuring the integrity of a 90° angle
  • Measuring a 45° angle
  • Measuring the center of a circular object
  • Finding the depth
  • Simple distance measurements
  • It is composed of a ruler and one or more interchangeable heads that may be affixed to it. The most common head is the standard or square head which is used to lay out or check right and 45° angles. The combination square is one of the favorite tools for woodworkers, stonemasons and metalworkers.

309 Ledgend Square Certified 90° with a unique ABS support ledge, a permanently etched stainless steel blade with 22.5°, 45°, 67.5° and 90° angle markings for beveling and framing.


Try & Mitre squares consist of two straight pieces: the stock and the blade which intersect one another at either 45° or 90°. A try square is both a woodworking and a metalworking measuring tool.

301 T-Bevel With a built-in 5mm (3/16″) trim gauge on the side and the bottom, a leveling vial and angle markings on the handle, the 301 T-Bevel helps you get accurate angles faster.


A sliding T bevel, also known as a bevel gauge or false square is an adjustable gauge for setting and transferring angles. The handle is usually made of wood, metal or plastic and is connected to a metal blade with a thumbscrew or wing nut. The blade pivots and can be locked at any angle by loosening or tightening the thumbscrew. The bevel can be used to duplicate an existing angle or set to a desired angle by using it with any number of other measuring tools. An absolute must tool in any construction, renovation or non-standard angle projects.
