Measure first
Nominal timber sizes are not actual sizes. A 6x6 is usually 5.5" and an 8x8 is usually 7.5". Measure your timbers and tell us if they're different. Odd sizes and pitches go through the custom quote, and we send a proof before we cut.
Images are renderings and drawings from our own CAD until the first sets are cut. Raw steel color and mill scale will vary.
Questions
How many do I need?
Two sets per truss, one for each face.
Do these brackets carry load?
No. They are decorative only. Your framing must stand on its own without them.
Is hardware included?

What finish?
Raw unfinished steel. It will rust outdoors if left unprotected. Powder coat is coming later.
When does it ship?
Default ship-by is mid-January 2027. We confirm a date for your place in the queue.
