Abstract

An assembly ties together a plurality of boiler tubes to increase their mechanical stability and maintain a uniform spacing between adjacent tubes. A tie bar has a plurality of periodically spaced fingers extending from a cross member to form openings between adjacent fingers with in which the boiler tubes tightly fit. A retainer projects orthogonally from ends of some of the fingers. A locking bar has wedges spaced along one edge which engage the retainers clamping the boiler tubes between the fingers of said locking bar. Stops and brackets attach to the boiler tubes to support the fingers and cross member, thereby holding the tie bar in place during assembly.
