The Sigma Table Joining Brackets (ART.439) are designed for tile pros who want a longer, more stable workstation when handling large-format tile, porcelain panels, and slabs. When a piece overhangs the edge of a single bench, it’s easier for the material to sag, rock, or shift during layout and handling. By connecting two Sigma workbenches into a single setup, ART.439 helps create a more continuous support surface so long material stays flatter and more controlled from end to end.

These brackets are made specifically for Sigma 63E / 63F / 63G modular workbenches, making them a smart add-on for crews already running Sigma bench systems on slab and LFT installs. A joined bench setup can make day-to-day tasks smoother—like dry-fitting, marking, staging panels before cutting, and supporting material before and after edge work—because you’re not constantly fighting unsupported ends. The result is a cleaner workflow with fewer awkward handoffs, better stability when moving pieces, and a setup that’s better suited to the size of tile you’re working with.

Whether you’re setting up a dedicated long station in a shop or building a bigger platform on-site, the Sigma ART.439 joining bracket is a simple way to turn two benches into one longer worktop and keep large-format material supported where it matters most.
