Excellent quality- playground worthy! These brackets are EXTREMELY HIGH QUALITY- SOLID, strong, rugged- we could not be more impressed. We used a 12’ beam across and 10’ for the legs- this set is gorgeous, strong, and amazing. My husband used his power tools to do the build, and  we had it built really fast! There are a ton of how to videos for this bracket set on YouTube. The wood for perfectly into the brackets. Super easy!!
