How to remove the cat's eye of threaded mouth

We can also screw the inner ring directly into the cat's eye, which requires a little force, and we can directly pull it out counterclockwise until it is very loose.

Look at the sign of the security door.

Anti-theft safety doors must go through strict examination and approval when entering the market. When shopping, be sure to confirm whether you have an anti-theft sign and its authenticity. The signs of these "security doors" are generally posted on the upper corner of the inner facade. The latest safety level is divided into four levels: "A, B, C and D". The higher the grade, the higher the safety factor of your security door.

Select the size of the door according to its opening.

The thicker the security door, the better. We also need to combine the size of the actual door frame at home to decide. We usually measure the size and thickness of the security door according to the space at the door. If our doorway is standard but irregular in design, it needs to be adjusted according to local conditions and the position and width of one side.

Select anti-theft lock

The quality of the door lock is the key to the security door. If the anti-theft performance of the door lock is poor, it is useless to choose a thicker door panel. The most earthy way to know whether the door lock is of high quality is to weigh it. The heavier the lock core, the stronger the material. Of course, the more beads in the lock core, the better the quality.
