The single scollop style lamp shade frame is a type of bell shape bottom with an flat top ring, tapering out to the larger bottom scolloped ring. The scollop refers to the beautiful rounded curves at the bottom of the lamp shade frame. Each single scolloped style frame has 8 curves around the bottom, except for the small 5" clip on, these only have 6 scollops. These scolloped styled frames come in 8 sizes, from the small 5" frame, ideal for clipping on to the bulb for wall lights and chandeliers etc, up to the larger 22" standard lamp shade frame. The 8" up to the 22" can be made to hang from a ceiling flex..
