What Gauge Steel Do You Use?
We use 11 gauge, 1/8″ thick steel, which is the same as we use for 99% of our brackets. (We make some custom brackets using 16 gauge (1/16″), and some others at 3 gauge (1/4″), but mostly everything is our standard 1/8″ thick– super heavy duty, and able to take whatever project you throw at it!)
Do Your Brackets Fit True 6″x6″ and 4″x4″ (aka “True Dimensions”), or Are They 5 1/2″ x 5 1/2″ and 3 1/2″ x 3 1/2″ (aka “Actual Dimensions”)?
Our standard brackets are made to fit the usual posts you find at Home Depot and other lumber retail outlets. This means a 4×4 post bought at Home Depot actually measures 3.5″ x 3.5″. This is know as “Dimensional Lumber” — every size is 1/2″ smaller than what it is called (so the commonly known 2×4 actually is 1.5″ x 3.5″!). Our brackets are made to fit these common Dimensional Lumber sizes. The photo to the right shows our standard Outside Corner with measurements.
Of course, if you buy lumber at a saw mill, it tends to be the actual size, rather than dimensions. Our brackets will still work, but there will be 1/2″ of “reveal” on the edge where our standard bracket comes up 1/2″ less. If you prefer the look of full coverage, just reach out to us and we will make brackets to fit your actual timber sizes rather than dimensional sized.
Are Bolts Included with My Brackets Purchases?
No, currently we are not able to offer bolts.
All holes are sized for 1/2″ bolts or 1/2″ lag bolts, which you can find at Home Depot or other hardware store, but you can use 3/8″ if you pick up washers when you get your bolts.
What Brackets Do I Need to Build a Double Pergola?
Using 4×4 posts to build a Double Pergola:
* 4 Outside Corners
* 2 Flat T’s
* 8 Bent L Inside Corners
* Optional Black Powder Coat
If you also need to bolt it down, rather than set the upright posts in concrete, then you also will need 6 of our 2-Piece Post Bases.
How Do I Attach My Pergola’s Incoming Horizontal Beams to the Upright Posts?
Using our brackets to attach the incoming horizontal posts of your pergola to your upright posts, you miter the corners of your horizontal beams and rest them on top of the uprights. The bottom half of our Outside Corners bolt to the uprights, and the “ears” of the Outside Corners bolt to the two incoming horizontal posts.
Are Your Brackets Offset to Avoid Bolt Collision in Build Construction?
Yes, we designed our brackets to allow them to be used together. You can use a Bent L as an inside corner if you like, and the holes line up with the Outside Corner so that you can layer steel/post/steel and even bolt all the way through (or use 1-3/4” lags for 4×4 posts, and 2-3/4″ lags for 6×6 posts, so they do not hit– which you can pick up at any local hardware store).
The Double Inside Corners also work. The holes for the upright align, so you have the option to bolt through. For the ears, they are offset, so that they do not collide.
