1) Generally, the opening and closing frequency of indoor doors is high, but the requirements for sealing performance are not high, and a single-point door lock with convenient operation can be selected.
2) Doors that communicate with the outside (such as balcony doors, corridor doors in hotels or offices, etc.) should try to choose a multi-lock point door lock with good sealing performance to improve the energy-saving effect of the building.
3) For some occasions with higher requirements for anti-theft, you can choose to use a door lock with a lock hook.
