TOPS™ Add-On (Home Line)

The TOPS ADD-ON™ is the key to expanding your modular pergola beyond a standard 3-post layout. Designed to slide into existing TOPS connectors like the TRI-TOP, this add-on creates an additional beam connection point without disrupting your base structure. Each module fits snugly and locks in with four strategically placed screws. Crafted from the same powder-coated galvanized steel as the rest of the TOPS lineup, the Add-On delivers both strength and simplicity. Add one. Add more. Build out your vision. (Currently available in 4x4 size. 6x6 sizes coming soon.)
