The eyes of the tape measure. Those who have used a tape measure know that once the tape is removed, it has a small circular hole in the head. This eyelet is the eye of the tape measure, and this eye can be very useful. It can help you measure distance accurately and reduce errors. When we need to measure the distance, we can use a small stick or other tool that can be inserted into the eyelets, attach the top of the tape measure and wait, we can pull the tape measure the distance. This helps you fix the measuring tape and not let it move at will, and leaves you free for other tasks, which is very practical. Two favorites: the zigzag of the tape measure. When you use the tape measure, you don't know if you have found it. There is a piece of serrated iron under the head of the tape measure. This sheet is the teeth of the measuring tape and is used for marking. When we measure, we can use this lace to make a line on the area to be marked and we can mark. Three good things: dimensional marking of the measuring tape. Those who have a tape measure at home can roll it up and watch it. There will usually be a size logo on the case of the tape measure. What is this logo for? This dimensional identification is actually the length of the tape measure case. Because a lot of times we measure distance we run into places that aren't measured well like the corner of the wall, the corner. It is very convenient if we know that the case of the tape measure is a dimensional sign. We can directly put the tape measure and tape measure case at the same level. Just add the length of the tape measure case.
