Overview: The article describes about Trim-able Open Web Floor Truss. Open-web, or parallel flat chord trusses, represent the predominate type of floor truss used in homes. They typically consist of a wood top and bottom chord, usually 2x4 material, and wood web materials connected at joints with metal plates. A few manufacturers use steel webs. One advantage of open web member over dimension lumber or I-joists, is that the open space between web members allows for easier routing of utilities. One downside is that truss dimensions must be known in advance to fairly close tolerances. Manufacturers and codes generally do not permit trusses to be trimmed or altered in the field.
