2-POST ADD ON KIT
The TOPS™ 2-Post Add-On Kit makes it easy to grow your existing pergola into a larger, more dynamic layout. Whether you’re extending a side, creating an L-shape, or building toward a full wraparound design — this kit gives you the flexibility to build your way.
With two Tri-Top™ connectors, two Add Ons, and two Post Bases, you’ll have everything you need to add two additional vertical posts and expand in any direction.
EXPAND YOUR PERGOLA WITH TOPS™ ADD-ONS
TOPS™ Add-Ons are the key to transforming your pergola from a basic frame into a truly customizable structure. These modular extensions attach directly to existing Tri-Top™ connectors, allowing you to build more complex joints like Tetra-Tops™ (4-way) or Penta-Tops™ (5-way) with ease.
Installation is simple: just insert the bottom tabs of the Add-On into the Tri-Top™, lift it into position, and secure it using the four included stainless steel #14 x 1" self-drilling screws. This flexible system means you can expand your pergola as your needs grow.
To complete installation, you'll need a 3/8" hex head bit that’s 6" long, either on its own or with a bit extender.
