Most frame tents from Celina Tent are designed to use the West Coast Style Frame system that is standard for the US tent industry. Frame tents are supported by a free-standing frame, thus eliminating all center poles or obstructions within the tent. Free-standing refers to a frame tent's ability to not require an anchor system to maintain its shape and stay standing; frame tents do require an anchoring system to secure it to the ground during inclement weather. When assembled indoors a frame tent does not need additional anchoring.
