Often, when conducting some finishing work, there is a need to mark. In this case, it may be very handy to be a male cord. It is used if it is necessary to lay a tile, build any structures made of drywall, pour a screed.
The design of this device is as simple as possible: the box in which the coil with a cord is placed, one of the ends of which is displayed out. At the end of this cord, a special metal petal is fixed, through which the cord is very convenient to pull.
In addition to the coil in the case, there is a special chalk -shaped chopped, painted in a red or blue shade. This chalk can be filled as necessary. For this there are special bags with a similar chalk, and the hole is provided on the case itself.
The stretched cord must be delayed and released sharply, while on any surface there remains a clearly noticeable and at the same time completely even trace. In order for the line to be clearly visible, before using the cord it must be carefully shaken. The strip is clearly visible on surfaces such as brick, concrete, glass and wood.
