RAKU Topclip Parapet Capping Joint

The Topclip joint is an ingenious method of jointing cappings, copings, ridges, roof edges, window cills & cornice flashings, suitable for all current metals such as copper, zinc, stainless steel & aluminium.

The joint has a double vulcanised rubber strip attached to either 1.2mm aluminium or 0.8mm stainless steel (for use with copper). The standard length is 3000mm and is cut to length and folded as required.

The two vulcanised 8mm high sealing strips huddle against the capping profile and build a safe barrier preventing capilliary penetration of rainwater.
The Topclip is easy to fix and does not require soldering, sealing, special skills or any additional expansion joints. The open joint guarantees expansion / contraction without any restriction.
