Center opening VVVF door operator | JJ:900 | 6.0000 |
This door opens very smoothly. It doesn't squeak like before, and it's very worry-free to use. The installation was also easy. The master was very professional, and it was done very quickly. There are elderly and children in the family. This kind of automatic door is really much more convenient and has a strong sense of security.
