# Extension Coupler

## Abstract

A system and method for an extension is disclosed. The extension attaches to a structure, such as a trailer. The extension has two sides. There is a planar surface connecting the two sides. The planar surface can be located atop, the sides, to the bottom of the sides, or along the length of the sides. Each of the sides has an upstream end and a downstream end. Each side has a vertical slot creating mounts located in the upstream end of each side. The mounts are for coupling to a structure, such as via pocket stakes.
