The term GATE PART refers to two components of a gate, which is an entrance or exit point in a wall or fence. The first component is a LATCH, which is a device used to hold a door or gate closed. It is usually operated by a handle or lever and can be opened from either side. The second component is a HINGE, which is a mechanical joint that connects two pieces of material together and allows them to move relative to each other. Hinges are typically used to attach a gate to a post or wall.
