Plastic inspection ports are mainly used in buildings and home environments.
On the ceiling, when it is necessary to inspect, repair or maintain the hidden pipes (such as water pipes, wire pipes) and equipment (such as the internal unit of the central air conditioner) inside, plastic inspection ports provide convenient access. For example, if there is a leak in the upstairs bathroom, the water pipe can be quickly checked and repaired through the plastic inspection port on the ceiling.
In terms of walls, some residential and commercial buildings have wiring and pipeline facilities inside the walls. Plastic inspection ports facilitate electricians or plumbers to troubleshoot and maintain. For example, in the office, network cables, wires, etc. can be maintained through the inspection ports on the wall.
For some integrated furniture, such as integrated cabinets, plastic inspection ports can be used to check the wiring connection of internal electrical appliances (such as disinfection cabinets, ovens, etc.) or the condition of the water pipes under the sink.
