# Overview and Features
Square and rectangular metal tubing are among the most commonly used robot construction materials in the FIRST Robotics Competition world. Most of the time, teams will use welding or gussets connected to holes in the tubes to mount parts to tubing, but not every team has access to welding, and sometimes gussets don’t easily accomplish teams’ design intent. Our solution to this is Tube Plugs!
