Rating of the best squares for 2022

Installation and construction work requires high precision. To do this, people use a variety of measuring tools. Verification devices are often used. These include a square, which is designed to measure and fix two planes perpendicular to each other.

Tool device

The square is a measuring attribute. It consists of 2 rulers, which are fixed to each other at an angle of 90⁰. It is used in a wide variety of industries. It is especially popular in construction, carpentry and metalwork production, it is necessary for drawing straight lines located at an angle of 90 on workpieces.⁰.

It is also used as a verification device. The device is multifunctional. With it, you can draw lines at any angle. They check the surface for compliance with the perpendicular.

The main advantage of the measuring instrument is its simple design. The device has a low price. If desired, it can be made by hand. To do this, you need 2 rulers, which are connected at the ends in a strictly perpendicular arrangement. The tool will help to apply not only lines at right angles, but also parallel markings.

The square is indispensable for masons, carpenters and builders.

Production material

Various components are used for production. Manufacturers use plastic, metal and wood. Metal is considered the most reliable material. Such models have sufficient strength. They are not subject to deformation. This moment is very important in the construction industry. Measuring scales are located on one or two sides of the device. They are designed for marking and distance control.

The length of the rulers varies, this figure varies from 60 to 1600 mm, it all depends on the scope of the product. Usually the tool is shaped like the letter G. Therefore, at home, many people call the device a corner. On sale you can see a universal device. It has a swivel joint at the junction. This makes it possible to set not only the perpendicular. The tool is called small.For the production of metal corners, steel grades such as X, U8A, ShKh15, 9X are used.

A quality tool must be heat treated. This allows you to get high hardness, which has a positive effect on the operation of the device. There are 3 accuracy classes (0, 1, 2). Zero is considered the best. This tool is used for verification work. Metrological laboratories also use them. Class 1 models are popular in the construction industry, plumbing and carpentry. The second class has inaccuracies in work. It is usually purchased for use at home.

Verification products

Produce 5 types of devices designed for verification. With their help, you can control the perpendiculars on the workpieces in different areas. Manufacturers offer a wide range of devices with different sizes and purposes.

1. Lekalnye devices have a designation in the form of letters UL. With their help, you can apply a variety of markings. Professionals use it to control the perpendicular on parts and structures during manufacturing processes. The device has high accuracy. This is his advantage. Sharp measuring planes provide a positive result. The short ruler has a thickened size. The long part has a thinner profile.
2. Flat curved fixtures have the abbreviation ULP. Unlike the previous model, both rulers are made of material with a thick profile. They are easy to use on a flat surface.
3. Cylindrical curved products have the designation ULC. The model has significant differences in design. The device resembles a cylinder with chamfers.The base with the side plane form a high precision right angle. The device has unique characteristics. Therefore, it is used in the engineering and metrological industries. Products are produced not only with zero accuracy class. On sale you can see fixtures with the first category of measurement and different lengths.
4. flat views. They have the designation UP. Both rulers are made from a flat profile. This type is considered the most common. It is produced with an accuracy class from 0 to 2.
5. Wide designs. This tool got its name because of the enlarged one side of the fixture. A wide profile is conveniently placed on a plane without support. This provides additional convenience when working. Products are marked in the form of the abbreviation УШ.

For home use, people usually purchase simple corners made from a flat profile. Such devices are of 3 types. They should be carefully studied. Knowing all the designs of flat tools, it will be much easier for anyone to make a choice in favor of a particular model.

Flat structures and their scope

Measuring devices are manufactured in different modifications. They are divided according to the method of application:

1. Manufacturers make carpentry models from wood or metal. Products have found active application in the woodworking industry. The length can be in the range from 10 cm to 10 m.
2. Marking devices. Devices have their own specifics. They are designed for drawing marking points with a pencil or marker. For this purpose, there are special holes in the guides. With their help, markup is applied.
3. Combined models. The two parts of the device are connected to each other by a movable hinge.This design allows you to set an angle of any size on the workpiece. On the handle is a small container filled with liquid. In a transparent chamber, on top of the water, you can see an air bubble. It will help to accurately set the horizontal and vertical workpieces at the right angle.
4. Magnetic devices. This is a separate type of product that is popular with welders. The design is equipped with powerful magnets that perform the function of fastening metal parts at right angles. After the workpieces are securely connected to each other by a welding machine, the tool is removed.

On sale there are devices made in the form of an isosceles triangle. One corner of the device must be straight. The structure is highly durable. This has a positive effect on the measurement accuracy. They cost more than conventional devices. However, the accuracy class offsets the costs.

Selection Guide

The choice must be taken seriously. First of all, you need to determine the direction of the work that the tool will perform. Based on this, the accuracy class is selected. If you want to take measurements with a minimum error, then you need a device with reliable indicators. In this case, the accuracy class must be 1 or 0. Working with wood or metal blanks requires a different approach. In this case, you can purchase a device with a second accuracy class. Everyone selects the tool according to their needs and requirements.

Many users buy measuring devices in online stores. In this case, the following factors must be taken into account:

1. Dimensions. The instruments have different lengths of both rulers. The higher this indicator, the more accurate it will be. It is rarely necessary to purchase an oversized device.To work with small parts, you will need a medium-sized device. For example, when laying ceramic tiles, a tool with dimensions not exceeding 30 cm is suitable. A device that is too large will be inconvenient to use. This fact must be taken into account.
2. Measurement angles. If marking right angles is required, then you should not buy a complex tool. Any classic model will do. Two rulers will be connected by fixed fasteners. This design will last a long time, because it is simple and reliable.
3. The presence of digital markings. In this case, the device can be used not only for drawing right angles. Experienced craftsmen carry out detailed marking and measurements.
4. Profile quality. You need to pay attention to several things. The dimensions of the profiles must match. This is essential for quality work. The long base should have a greater thickness. The proportions must be correct. If the length of the working part is very large, and the base is thin, then the device will take measurements with a large error. This fact must be taken into account when buying. The length and thickness of the rulers must be balanced.
5. Manufacturing material. The most common are metal products. Differ in the high durability and durability. Their resource is not limited. Will last a very long time. However, in some cases, it is not very convenient to work with a metal fixture. Therefore, many craftsmen prefer devices made of wood and plastic.

Given all the features, everyone chooses a tool according to their needs and requirements. It is necessary to calculate the scope of work, operating conditions and dimensions of the workpieces.
