The TOPS 4-Post Kit includes everything you need to build a sturdy, modular 4-post pergola foundation — no guesswork required. With four Tri-Top connectors and four Post Bases, you can create a square or rectangular layout that’s ready to grow with your vision.
Each Tri-Top forms a clean 3-way junction with one vertical post and two horizontal posts, while the Post Bases secure your structure to a deck, patio, or footing with strength and style.
Compatible with: TOPS 2-Post Add-On, Pergola Foot Anchor, and Louver Tops.
(Currently available in 4x4 size. 6x6 sizes coming soon.)
