GRID 30 Double Pergola Kit for 4x4 Wood Posts
Create and build to your size and space with the GRID 30 Double A-frame Pergola Kit! It adds onto the single pergola kit with two QUAD 30 and a PEAK QUAD 30 that allows you to extend the size of your pergola structure and accommodate a larger space.
The GRID 30 Collection was designed and developed to allow you to build an angled and peaked roof pergola. GRID 30 brackets are not structural brackets or intended to have fixed roofs, customization or anything outside the intended and indicated use of pergola as shown. For anything outside our recommendation, we advise consulting with an engineer. Always check your local building codes, HOA, and municipal requirements in advance of building as they vary by city/state and region.
• See sizing chart for reference of wood. We advise consulting with your local building codes.
• Ensure lumber is fully inserted into the bracket cavity, resting on metal tabs for proper installation.
