CNC machined aluminum glazing caps are designed to fit on a standard 50mm glazing post, commonly used for glass pool fencing and glass balustrade. The 2 way cap includes cutouts (pictured left) to allow the glass panel to go through. The multi glazing cap has no cut outs. These caps are made to be knocked in with a rubber mallet firmly for a permanent fit, no adhesive or weld required. A beveled edge on the underside makes for easy installation. Simply tap into place.
