2-Hole 90° Strut Corner Angle
Create a strong 90-degree connection between strut channels mounted on different planes. This heavy formed-steel corner angle has one mounting hole on each leg, making it a simple and dependable way to build frames, supports, shelves and equipment structures.
Made from 1/4″ thick steel with a Hot Dip Galvanized finish, it delivers substantial strength and long-lasting corrosion protection for indoor or outdoor installations.
Why You’ll Love It
- True 90-degree connection — joins strut channels positioned on different planes
- Heavy 1/4″ steel — a substantial fitting for dependable support
- Simple two-point installation — one mounting hole on each leg
- Indoor or outdoor versatility — Hot Dip Galvanized for durable corrosion protection
Choose a flat corner plate when both pieces of strut channel meet at 90 degrees while remaining on the same plane. Choose this formed corner angle when the channels, brackets or mounting surfaces are perpendicular to one another.
The two formed legs create a direct right-angle connection without stacking flat plates or fabricating a custom bracket. Building a flat, face-mounted corner instead? Our 3-hole strut corner plate provides a clean connection across the front of the channel.
Build Clean, Compact Corners
The compact two-hole design is easy to position inside or outside a strut-channel corner. Each leg has a centred 9/16″ mounting hole, allowing the angle to connect directly to compatible strut nuts and fastening hardware.
Use it for equipment frames, shelving, wall supports and other structures where one piece of channel must connect squarely to another. Its compact footprint delivers a clean finished assembly without unnecessary bulk.
Durability for Any Installation
Hot dip galvanizing surrounds the fabricated steel fitting with a heavy, bonded zinc coating. This provides excellent protection against moisture and corrosion while maintaining the strength of the underlying 1/4″ steel.
It is an excellent choice for outdoor equipment and exposed structures, but it is equally useful in workshops, equipment rooms, warehouses and utility spaces where long service life and minimal maintenance are priorities.

Frequently Asked
What type of connection is this angle designed for?
It creates a 90-degree connection between strut channels, brackets or mounting surfaces positioned on different planes. One leg fastens to each side of the completed corner.
How is this different from a flat corner plate?
A flat corner plate joins two pieces of channel that meet at 90 degrees while remaining on the same plane. This formed angle connects components or channel sections that are perpendicular to one another.
If your connection must turn around a corner or transition between horizontal and vertical mounting surfaces, this formed angle is generally the better choice.
Can I use this corner angle indoors?
Absolutely. Its compact size and durable finish make it an excellent choice for workshops, equipment rooms, warehouses, shelving and indoor utility structures.
The Hot Dip Galvanized coating provides additional protection in locations that may experience humidity, condensation or occasional moisture.
Is it suitable for outdoor installations?
Yes. The Hot Dip Galvanized finish provides durable corrosion protection for outdoor, damp and exposed installations. For the best complete assembly, use channel, strut nuts, bolts and adjoining fittings selected for the same environment.
Do I need washers when installing the angle?
Yes. This fitting works best with 3/8″ or 1/2″ bolts installed using heavy-duty flat washers. The washers provide a broad bearing surface beneath the bolt heads, distribute clamping force across the fitting and properly cover the 9/16″ mounting holes.
Washers are especially important when using 3/8″ bolts because of the additional clearance around the smaller fastener. Select the bolt length and other hardware to suit your strut channel, spring nuts and completed assembly.
Should I use both mounting holes?
Yes. The angle is designed to be secured through both mounting holes, with one fastener on each leg. Using both attachment points provides the intended alignment and support across the 90-degree connection.
