What preparations should be made before installing the access door

size measurement Accuracy:

accurately measure the opening size of the installation location, including length, width and depth. The measurement error should be controlled within a small range (usually 1-2 mm) to ensure that the access door can closely fit the installation site. Reserved space: Consider the installation method of the access door and the space requirements of hardware fittings. For example, when embedded installation, a gap of 2-3 mm is reserved for easy installation and adjustment; When surface mounting, enough space should be reserved according to the size of the mounting bracket.

Environmental assessment Smoothness:

Check the smoothness of the wall, ceiling or equipment surface around the installation location. If the surface is uneven and the difference exceeds 3 mm, it may need to be trimmed, such as leveling with putty or cement mortar, to ensure the flatness and tightness of the access door after installation. Humidity and temperature: Pay attention to the humidity and temperature conditions of the installation environment. If the ambient humidity is high (more than 70%) or the temperature is too high (more than 40C) or too low (less than 5C), the performance of some access door materials (such as wood and glue) may be affected, and corresponding moisture-proof and thermal insulation measures need to be taken.
