Custom Angle Bracket

Custom or stock

We keep ten stock angle brackets in the same 1/4" steel: 4" or 6" wide, with two equal legs from 4" to 12" long, square corners, and holes for 5/8" bolts. If one of those fits your joint, order it. Design your own when you need two different legs, another width, a different bolt, or clipped corners.

Sizes this bracket is made in

• Legs: each 4" to 12" long, set one at a time. The configurator calls them height and length.
• Width: 3" to 10".
• Bolts: 1/4" to 3/4".
• Corners: square, or clipped 1/2".

Leg lengths are measured on the inside of the bend. Legs and width step by 1/8", and bolt sizes by 1/16". The configurator opens on a 6" by 6" bracket, 4" wide, with 5/8" bolts. For a bracket outside these sizes, an angle other than 90°, or slotted holes, use the quote form.

How the holes are laid out

The holes follow from the bolt you choose. The first hole in each leg is 1" from the leg's free end, or 1 1/8" for 11/16" and 3/4" bolts, so a standard flat washer stays at least 1/8" back from the end. More holes follow every 4 bolt diameters toward the bend, and they stop 4 bolt diameters short of the other leg. A 6" leg with 5/8" bolts gets two: 1" and 3 1/2" from its end.

A bracket under 7" wide has one row of holes down the middle. At 7" and wider it has two rows, a third of the way in from each edge.

The rule this configurator enforces

Every leg has to be long enough for at least one hole. That takes the first hole's distance from the end, plus 4 bolt diameters to the bend. Bolts up to 11/16" fit the shortest 4" leg. A 3/4" bolt needs legs at least 4 1/8" long, so the configurator asks you to lengthen a leg or choose a smaller bolt.

Where it's used

• Under a beam where it sits on a post.
• Where a beam or a ledger meets a wall.
• At either end of a knee brace.
• Where pergola rafters cross their beam.

How much a bracket can carry depends on the timbers, the fasteners, and the load, so have your engineer check any joint that matters.

Questions

Which leg is the height and which is the length?

In the 3D view, height is the upright leg and length is the flat one. The bracket is the same part whichever way you turn it, so set the two legs to suit your joint.

Can I use lag screws instead of bolts?

Yes. Enter the screw's diameter as the fastener size. The holes are cut 1/16" over it, and their spacing follows that diameter.

Is the bend exactly 90°?

No, and that's on purpose. We bend these slightly past square, so the bracket's corner seats tight and the bolts draw both legs flat as you tighten them. Expect the angle to be within 5° of square. If you need a bracket held to 90°, we can make it as a weldment: ask through the quote form.

Can you add a gusset?

Yes, by quote. We can weld a gusset into the bend for a stiffer bracket. Send the bracket's sizes through the quote form.

The basics

• 1/4" A36 steel plate, laser cut and bent slightly past square (within 5°) in our ISO 9001 shop in Texas.
• Holes are cut 1/16" larger than the fastener you choose. Fasteners aren't included.
• Sizing it to a timber? Go by the timber's real size, not its name. How to measure a timber.
• Bare steel, or matte black powder coat added in the cart.
• Ships free in the lower 48 states.
• No published load ratings. Ask your engineer, and see what to give them.
