8'x8' Frame -- 1" round tubing (part# 319413) by Matthews Studio Equipment:
In response to requests for a lower cost, price competitive overhead frame, Matthews now offers the "Just A Frame" series of overhead frames. While lacking the high degree of structural integrity of the "Hollywood" frames and the "SNAP A PART" frames, the "Just a Frames" will work well indoors or in other controlled environments.
Round tubing frames are 1" OD; in the case of 20'x20' size, it is 1-1/4" Sch. 40 pipe.
