Eaton Zinc Electroplated Steel 2-Hole 45-Degree Knee Brace
The Eaton Zinc Electroplated Steel 2-Hole 45-Degree Knee Brace is a B-Line series strut accessory engineered to reinforce diagonal support connections in structural framing and channel support systems. Built from durable zinc electroplated steel, this knee brace features a 2-hole mounting pattern and a fixed 45-degree bracing angle that adds stability at corner and diagonal junctions throughout a strut assembly. Electricians, contractors, and facility maintenance crews rely on this style of knee brace to stiffen strut-based support systems, reduce racking and flex, and keep channel framing square during installation and long-term service in commercial and industrial electrical environments.
Key Features
- 2-Hole Configuration: Dual mounting holes allow secure, aligned attachment to strut channel members for dependable, repeatable diagonal bracing on every installation.
- 45-Degree Angle: Fixed 45-degree geometry provides consistent diagonal support at framing corners and junctions, helping maintain square, stable channel assemblies.
- Durable Zinc Electroplated Steel Construction: The zinc electroplated steel body resists corrosion and everyday wear while providing the strength needed for demanding structural bracing applications.
- Knee Brace Design: Reinforces strut framing joints, reducing flex and improving the overall rigidity of the support system assembly under load.
- Strut-Compatible Mounting: Designed to integrate directly with standard strut channel support systems used throughout electrical, mechanical, and structural installations.
- Field-Ready Hardware: Compact, drilled design simplifies on-site fastening without additional field modification, helping installers work faster on strut runs.

Eaton B261-16-5/8ZN – Frequently Asked Questions
1) What is a 45-degree knee brace used for on a strut channel system?
A knee brace is the diagonal member that ties two strut channel legs together at a corner so the assembly stops racking under load. The Eaton B-Line B261-16-5/8ZN sets a fixed 45-degree angle, so it drops into a standard square corner between a vertical and a horizontal strut run and holds it square. Typical use is conduit and raceway supports, cable tray framing, and equipment support stands in commercial and industrial electrical work.
2) Is a zinc-plated knee brace okay outdoors or in a wash-down area?
The B261-16-5/8ZN is zinc electroplated steel, which is a corrosion-resistant indoor and sheltered-use finish. It suits dry commercial and industrial interiors, mechanical rooms, and covered spaces. For direct weather exposure, coastal air, or regular wash-down, specify a hot-dip galvanized or stainless strut fitting instead.
3) Will this Eaton B-Line knee brace bolt to strut channel from another manufacturer?
It is built to mount to standard strut channel, and strut fittings follow a common hole and slot pattern across the trade, so the two-hole pattern lines up with conventional channel. Use the channel nut sized for the strut you already have in the building. Sticking with B-Line components through the run keeps bolt sizes and nut styles uniform across the assembly.
4) Can I adjust the angle on this knee brace to something other than 45 degrees?
No. The angle is fixed at 45 degrees by the geometry of the part, so it only works where the two strut legs meet at a square corner. For a brace you can set to an arbitrary angle, you need an adjustable or swivel-type strut brace fitting rather than this one.
5) How many bolts does the Eaton B261 knee brace take?
Two. It is a 2-hole brace, one fastener at each end into the strut channel. You supply the channel nuts and hex head bolts to suit the strut you are running; the brace itself comes drilled and ready to bolt up with no field cutting or drilling.
6) What model number do I order for the Eaton zinc 2-hole 45-degree knee brace?
Order Eaton B-Line part number B261-16-5/8ZN. That is the single configuration: 2-hole, fixed 45 degrees, zinc electroplated steel.
7) Do I need a knee brace on a strut trapeze hanger, or is the channel enough on its own?
A bolted strut corner alone will flex and rack under side load or vibration. Adding a diagonal brace at the joint stiffens the frame and keeps it square over the life of the install. Facility crews use them on wall-mounted conduit racks, cantilevered supports, and free-standing equipment frames where the load is not purely vertical. On a plain overhead trapeze hung from two rods, bracing is usually unnecessary.
