What if there is no anti-theft chain on the hotel door?

There is no anti-theft chain to feed back to the waiter. You can also change rooms. In fact, this is an auxiliary anti-theft tool. If there is no cat's eye, you can keep the anti-theft chain first, open the door for dialogue, and then open the anti-theft chain after confirmation. If the anti-theft chain has the sound of metal collision, it has a certain anti-theft effect at night.

The function of security door chain:

The chain buckle is installed on the back of the door, not far from the door edge. One end of the sliding chain is fixed on the door frame, and the other end is movable and can be inserted into the chain buckle behind the door for locking.

When hanging the anti-theft chain, the door can only be opened about 5~8 cm at most, so that people can't get through it and their hands can't reach the chain buckle behind the door, ensuring that the host will not be suddenly attacked by the other party when he opens the door to confirm the identity of the visitor.

Because the sliding chain is easy to be cut by tools such as metal cutting pliers, the security door chain is rarely used as a door lock alone, but only as an auxiliary tool for theft prevention.

Therefore, the sliding chain and sliding buckle security door chain is also called "intentional lock", which is intended to remind people to be more careful just in case. In addition, there is a kind of "safety door buckle" which uses metal rod instead of metal chain, which is also designed and used for the same reason.
