If the installer is not properly aligned and the left and right plates are not installed correctly, even the slightest difference in the alignment of the plates can cause the door to move up or down and lock after about a month. For this reason, the installation must be done by an experienced and professional installer. Also, there is information on the door motor that only an experienced installer can correctly identify its function. For example, if we have a left-handed motor and the inexperienced installer does not know how the motor rattles, the beauty of the part may be important to the manufacturer, but it is not important for the performance and longevity of the door. Another point that the installer should pay attention to is the door handle. If the hog chain breaks, until it works firmly off the hog, it is locked as the hog chain slips. But, many inexperienced installers do not pay attention to this point and think that because the chain looks strong, there is no need to pay attention to its use.
Why should installers install the door?
According to YouTube tutorials, people can install their own doors, but it should be noted that an experienced installer will do this with minimal damage. An experienced installer has the skills to ensure that the door is installed correctly and does not run into problems.
