Modern's 4' x 4' breakdown frame comes complete with:

• (4) 46" lengths of 3/4" Square Aluminum
• (4) Corners
• (2) Sliding Pins

We manufacture all of our corners with stoppers welded into the interior, which allows you to quickly and easily create a perfectly square frame every time. Please note that we cut the square aluminum to 46" lengths in order to accommodate for these stoppers, to insure you a true 6' x 6' frame after assembly.
