This is the official FIRST Tech Challenge Perimeter. 
This is reusable from year to year and does not include soft tiles, game-specific hardware, components, or game pieces.

The perimeter is comprised of eight hinged panels and four straight panels. Once assembled, the perimeter creates an 11 feet 9 inch by 11 feet 9 inch square enclosure. The hinged corners and quick release pins make for easy assembly, requiring no tools. Side panels include a built-in wire way for easy cable management.
