![]() ![]() The absolute minimum is two rivets that ensure the stability of the hook. The number of rivets with which the hook is attached to the measuring table is important. The hook itself should be made of stainless steel, and this is the case with PRO products. After all, the hook itself is also thick, and the lack of movement would make the measurement inaccurate by even a few millimeters. If so, good! All the hooks in the PRO brand measures are movable, thanks to which the measurement is more accurate. When choosing a retractable measure, first of all, pay attention to whether the hook moves. Tape measure hook - a key element affecting the convenience of measurement The springs are fatigue tested and the tapes are pulled 3,000 times 1.8 cm outside the measuring range. PRO prides itself on the fact that before tools are offered to customers, they undergo rigorous durability tests. As we mentioned, impact resistance is not all about endurance. the PR-60-05 measure, are equipped by PRO with a shock-absorbing bumper. The tape hook strikes the housing while retracting. It turned out that the fall did not affect the functionality of the tape measures and the shape of the housing. This has an impact on the tool life, after all, differences in thickness on individual sections of the tape adversely affect the retraction mechanism.Īlso in this matter, tests are carried out, which consist in checking the behavior of the material after a fall from a height of 1.2 m. PRO uses ultra-tough, high-quality carbon steel to ensure the tape is of the same thickness along its entire length. If you are wondering what are the differences between a tape measure for a few bucks and the one for a dozen or so, the answer may be the quality of the tape itself. Remember that the PRO offer includes both short professional measures, 2 m long ( PR-45-12), as well as very long ones ( PR-60-02). You will see what this means in the table below. In our offer you won't find class III measures. For example, a Class III measure at a distance of 5 m has a tolerance of ± 2.6 mm.įor comparison, a class I measure at the same distance will have a tolerance of only 0.6 mm, so the possible error is much smaller.Īll PRO measures meet the strict EC tolerance requirements for classes I and II. The cassette itself is constructed in various ways, which significantly affects its durability and ergonomics of use.īefore choosing a tape measure, think about the accuracy class you need for your work! Remember that each measure, even a certified measure, has a certain tolerance. To roll up the tape it is necessary to release the brake lock. However, a reverse brake is present in many products, such as PR-60-05 i PR-60-11. It is a construction in which the tape locks automatically when ejected. A popular solution is the so-called "classic brake" - if you do not tighten the lock, the measure will roll. Since the measure is to roll up, you need a suitable mechanism along with a brake. It should be properly profiled so that it does not break when pulled out to a distance of only a few centimeters. The fundamental element of a tape measure is, obviously, a tape. However, do you choose your tape measure consciously? Do you know all its possibilities? Do you know why some tape measures are more expensive while some are cheaper? We answer these and other questions in the following text, revealing all the secrets of this small but meaningful tool. Without it, it is impossible to make accurate measurements.
