Stop bracket

The stop angle is a teaching and embodies a certain angle , usually 90 °. It is mainly used by carpenters and locksmiths to sketch out right angles , to check work that has already been carried out and to align various elements with one another.

use

The stop angle is considered a testing tool , as it can be used to check workpieces and walls to determine whether or not there is an angle of 90 °. Further, it can also work well as scribing tool can be used, as it is a straight line with a by applying on a smooth surface of the workpiece on the parallel surface pencil or scriber can Mark.

Executions

The stop bracket typically consists of two legs of unequal length with a guide bar or stop on the shorter leg so that it can be placed against edges. Locksmiths use angles made of steel, usually made of one piece, sometimes rustproof galvanized. Carpenters often use angles made of wood, or with a stop part made of wood and a stop edge covered with brass, and long legs made of spring steel, the legs riveted. Cheaper models are made of aluminum, the legs are riveted or glued.

Brackets without a stop bar are called flat brackets . The hair corner is used for precision tests .

accuracy

In Germany, the DIN 875 standard specifies the most important design and measurement features and their testing. According to this standard, stop angles as well as flat angles and hair angles are divided into tolerance classes 00, 0, 1 and 2. The tolerance class is usually specified as the accuracy quality or degree of accuracy (abbreviated as GG 00, GG 0, GG 1 and GG 2). The steel stop angle is available in the tolerance classes according to DIN 875 or as a (non-certified) workshop angle, with 00 being the most precise tolerance. As a rule, the angles are sold with a corresponding test certificate.
