CPW will supply a hinge system that is to be attached directly to the core of your masonry column at a height called out in the CPW drawings. This hinge “sleeve” will arrive at the job site at a prescribed length prior to the gate’s arrival to facilitate the coordination and completion of pillar construction. Often times the concrete core will be surfaced with stucco, stone or veneer to fashion a masonry column. It is best to embed the CPW hinge system directly to the concrete core prior to the final masonry application.

To set the height of the hinge to the concrete core, use a transit. To bore into the stone or block, use a roto hammer drill, and bore the full depth of the hinge sleeve. Embed the sleeve into the bore with epoxy. The hinge sleeve can be cut to length on-site so the female-threaded end is flush with the final masonry application. If there is need for incremental height adjustment due to run-out on the boring bit, spacing washers can be added to the rob end of the hinge.

For gates without embedded steel frames, the opposite plate mounts to the edge of the gate with a provided 1/4" lag bolt. For gates with embedded steel frames, the opposite plate arrives already welded to the embedded steel frame through a mortised section on the edge of the gate.

Often, to protect against installation blemishes, the gates are
mounted while still shrink-wrapped, as shown.
