Many photographers has asked to make a background support system with heavy duty 10" stands and a 12" telescopic cross bar. We came up with this new background support system that has a maximum height of 10" and comes with a newly patented 12" telescopic crossbar. Made of black non-glare metal tube construction for extra heavy duty use. Holds canvas, muslin or paper. Non-slip rubber tips on legs to prevent movement. Solid locking/unlocking system to raise center poles. Solid oversized leg bracing. No rivets, we use only bolts to hold legs together. This system is heavy duty and will give you years of use. The stands on this system are all heavy duty and lock in place with metal die-cast locking collars (not plastic) to ensure greatest control, that will give you years of use. The crossbar on this system is the latest in crossbar technology, no extra external peices required to lock this on the stands, just snap the two peice telescopic cross bar together and extend it out from 6" to 12". The endcap knobs on this crossbar lock the crossbar to the support stands. This is newly patented system. No more wing nuts to lose.
