2-Hole Open 45° Strut Corner Angle
Build clean angled connections between sections of strut channel. This heavy formed-steel fitting creates an open 45-degree transition, making it ideal for braces, sloped supports and structures that need more than a standard square corner.
Made from 1/4″ thick steel with a Hot Dip Galvanized finish, it delivers substantial support and dependable corrosion protection for indoor or outdoor installations.
Why You’ll Love It
- Build angled supports — creates a clean open 45-degree strut connection
- Heavy 1/4″ steel — a substantial fitting for dependable support
- Simple two-point installation — one mounting hole on each formed leg
- Indoor or outdoor versatility — Hot Dip Galvanized for durable corrosion protection
Choose this open 45° angle for diagonal braces, sloped supports and other connections that change direction gradually. Its longer inclined leg provides a practical attachment point for angled strut assemblies.
Building a square frame or perpendicular support instead? Our formed 2-hole 90° corner angle provides one mounting point on each leg for a direct right-angle connection.
A Simple Way to Add Angled Support
The formed shape gives you two mounting surfaces set at an open angle. One hole secures the base leg, while the second connects the inclined leg to the adjoining channel, bracket or mounting surface.
Use it to add diagonal reinforcement, support sloped channel or create purpose-built frames without cutting and welding a custom fitting. The compact two-hole design keeps the completed assembly clean and easy to adjust.
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 preserving the strength of the underlying 1/4″ steel.
It is an excellent choice for exposed outdoor 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 does “open 45°” mean?
It describes the formed angle of the fitting and the directional change it creates between the connected components. Rather than making a square 90-degree corner, it provides an open angled connection for braces, sloped supports and similar structures.
When should I use this instead of a 90° corner angle?
Choose this fitting when one section of channel or support needs to run diagonally or at an open angle from the other. It is useful for braces, sloped frames and supports that transition gradually between mounting points.
Choose a 90° corner angle when the two channels or mounting surfaces are perpendicular and you need a square right-angle connection.
Can I use this angle indoors?
Absolutely. It is well suited to workshops, equipment rooms, warehouses, shelving and indoor utility structures. The Hot Dip Galvanized coating also adds 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 angled connection.
