Abstract
For connection of a series of balusters to a top rail, each baluster is provided with a pair of jaws extending upwardly from its top end. The top rail has an integral retainer ridge formed lengthwise on its bottom surface. The retainer ridge includes a pair of shoulders having transversely registered pairs of recesses at prescribed longitudinal spacings. A pair of grooves are formed lengthwise in the respective lateral surfaces of the retainer ridge, and another pair of grooves are formed lengthwise in the bottom surface of the top rail on both sides of the retainer ridge. The jaws of each baluster are inserted into the respective grooves in the bottom surface of the top rail via the respective recesses, and the mid-portions of the jaws are then caused to project into the respective grooves in the lateral surfaces of the retainer ridge by pressing operation. The balusters can likewise be connected to a bottom rail.
