Installation Guide

Everything You Need to Get Started

Our TOPS Connector Installation Guide walks you through every step of the build—from planning your layout to securing each connection with confidence. Whether you're assembling a simple pergola or expanding into something more custom, this guide has you covered with clear instructions and detailed diagrams.

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 (sold separately).
