What should I do if the beam hole of the anti theft door is large?

Hello friends, can you try what I said 1, the heaven and earth lock and the side lock (there is a connecting rod on the top and bottom) are hung on the hook of the lock body. 2, the upper connecting rod is easy to hang, due to gravity, the upper connecting rod is just opposite to the hook of the lock body, directly into the line, the lower connecting rod will go down a little (gravity), from the hole in the door on this side, take a screwdriver, pick up some of the rod, and then hang it on the hook. 3. Fix the lock body screws at the back, install the lock cylinder, install the handle without width, and then it's done. >>>More
