Genuine Unistrut P1325-EG 4 Hole 90 Degree Angle Connector Bracket
The Genuine Unistrut P1325-EG is a four-hole, 90-degree angle fitting designed for all 1-5/8″ series channels. Made by UNISTRUT, this connector provides solid corner support and dependable load distribution. Its four 1/2″ bolt holes ensure secure mounting at right angles, making it suitable for frames, supports, and enclosures requiring rigid corner joints in commercial applications.
heneng 4 Pcs 8 Hole Wing Shaped Fitting
The heneng wing-shaped brackets are designed for 1-5/8″ strut channels and feature a 3/16″ thickness. With eight holes arranged to accommodate 1/2″ bolts, these brackets offer flexible mounting options for mid-span connectors, braces, and cross supports in tight spaces where multiple fasteners are beneficial for stability.
4 Pack – 5 Hole, U Shaped Connector Bracket
This four-pack of heavy-duty U-shaped connectors uses 1/2″ bolts compatible with all 1-5/8″ strut channels. The brackets are electro-galvanized with a 1/4″ thickness to resist rust and corrosion, and they include five 1/2″ holes for versatile fastening in tight installations or where multiple fasteners provide extra rigidity.
4 Pack – 3 Hole, L Shaped Flat Plate Connector
The 3-hole L-shaped flat plate connectors offer a compact mounting option for 1-5/8″ strut channels. With a heavy-duty 3/16″ electro-galvanized steel construction, these brackets are zinc-coated to resist rust and corrosion. The three holes are spaced to align with corner placements or edge mounting, supporting strong, tidy assemblies in commercial and workshop environments.
4 Pack – 8 Hole, Wing Shaped 90 Degree Bracket
This 4-pack of 90° wing-shaped brackets is built for 1/2″ bolts in ALL 1-5/8″ strut channels. Constructed from 1/4″ thick electro-galvanized steel, these brackets provide robust strength and corrosion resistance. Eight holes arranged on the tall sides offer flexible fastening patterns for heavy-duty frame assemblies and support rails in industrial settings.
Buying Guide
Key considerations when selecting 4-hole unistrut feet and related brackets include material quality, channel compatibility, hole pattern, mounting orientation, and environmental conditions. Here are multiple perspectives to aid decision-making:
- Material and finish: Electro-galvanized steel offers corrosion resistance for indoor and outdoor use, while coated finishes may provide additional protection in harsh environments.
- Hole pattern and count: More holes can offer flexibility for precise alignment but may require longer bolts and careful fitment to avoid interference with adjacent components.
- Thickness and rigidity: A thicker bracket (such as 1/4″ or 3/16″) generally provides greater rigidity and load capacity, which is important for heavy-duty applications.
- Compatibility with 1-5/8″ channels: Ensure the bracket is designed for the same channel size to guarantee proper fit and safe operation.
- Installation environment: For high-moisture areas, stainless or zinc-coated options can reduce corrosion risk, while indoor applications may suffice with standard electro-galvanized parts.
- Ease of use and accessibility: Some designs are easier to install in tight spaces or require fewer tools, which can streamline project timelines.
- Cost and availability: Evaluate the total number of brackets needed and whether bulk packs offer better value for your project scale.
When comparing products, consider how the connector style aligns with your mounting strategy—angles for corners, U-shaped for frames, and wing-shaped designs for distributed load paths. Real-world use often benefits from combining multiple bracket types to address different load points and fit constraints.
