Abstract
A splice system having two rails to be connected end to end and splice member having a center part and a pair of end parts sized for insertion in open ends of the two rails. The rails to be connected end to end having first and second opposing walls and a hole in the first walls. The end parts of the splice members having threaded openings adapted to register with holes in the rails. The splice member is connected to the rails with bolts, the arrangement being such that, when the bolts are tightened, heads of the bolts outside the rails are drawn toward first walls of respective rails and end parts of the splice member inside the rails are pulled away from second walls of the rails and tight against the first walls of respective rails thereby to splice the rails together.
