what is Gate Drop Rod

A door hanger, also known as a door bolt or door anchor, is a security component used to secure a bi-fold door in the open or closed position. It works by sliding over a rail and into a hole in the ground, preventing the door from swinging freely. To unlock the door, lift the hanger out of the hole and turn it.
Hangers can be made from different materials, including aluminum, stainless steel, or brass. Stainless steel is a popular choice because it can be powder coated and electro-polished to increase its durability. Hangers also come in different styles, such as:
Heavy Duty Steel Tube: For chain link doors
Powder Coated: For wood, decorative, and vinyl doors
Lockable: Provides extra security
It is easier to install a hanger on large doors than a regular locking handle because you can make a larger hole to account for alignment issues. To install a hanger, you can:
Dig a hole in the ground
Line the hole with steel pipe or buy a ground block
If you are installing a bi-fold door, you will need to install a cane bolt on one side of the door so that the other side can latch it
