ABSTRACT:
A scaffolding system having a first frame connected to a second frame with at least one platform disposed therebetween. The first frame includes a first set of posts connected together by an upper cross member. The second frame includes a second set of posts connected together by a lower cross member. The platform is adapted to be detachably secured to the upper cross member and sandwiched between the upper cross member and the lower cross member such that an upper surface of the lower cross member is generally flush with the platform, thus forming a continuous walking surface. The lower cross member prevents removal of the platform while the second frame is connected to the first frame.
