Pheonix SCU – Universal Strut Clamps
The Pheonix SCU clamps are designed to fit both rigid conduit and EMT thin-walled tubing across multiple sizes. They arrive in standard manufacturer packaging with electro-galvanized finish. Application notes emphasize compatibility with common conduit and channel configurations used in double-strut installations, providing a versatile mounting solution for electrical and mechanical systems. Installation considerations include ensuring proper engagement with the channel and verifying that the clamp size matches the conduit or tube diameter to maximize load distribution.
heneng 4 Pcs Strut Beam Clamp (Back to Back)
These heneng clamps are configured for back-to-back mounting on tall strut channels, accommodating sizes from 1-5/8″ up to 3-1/4″. They feature a square U-bolt design and a robust load rating up to 1100 lbs per clamp, making them suitable for heavy-duty double-strut applications. The inner width and threaded M10 hardware contribute to stable clamping when paired with appropriate channels. When planning a double-strut setup, verify channel dimensions and bolt pattern to ensure secure alignment and minimized movement under load.
Newhouse Electric Channel to Beam Strut Clamp
This clamp is designed for securing channels to beams, a common requirement in double-strut arrangements where channel runners must be anchored to structural members. The unit supports 12- or 14-gauge channel profiles and uses a silver electro-plated finish for corrosion resistance. With a compact footprint (2-7/8 in. L x 3 in. W x 3-3/16 in. H), it can be a practical choice in tight installations while maintaining a solid connection between channel and beam. Ensure compatibility with the channel gauge and confirm the bolt pattern with the chosen beam member.
heneng 4 Pcs Strut Beam Clamp (1-5/8″ Channel)
This set is tailored for 1-5/8″ strut channels with a 3/8″-16 thread size and a 2″ thread length. Each clamp uses a 3/16″ thick plate for durability and reliable load transfer, making it a practical option for standard double-strut assemblies where uniform clamp spacing and secure mounting are required. As with similar clamps, consider channel compatibility and the intended load path when designing the system to avoid overloading any single clamp.
MorningRo 4 Pack U-Bolt Beam Clamp
The MorningRo clamp set is designed for 13/16″ to 1-5/8″ channels and features a heavy-duty electro-galvanized steel build. A U-bolt height of 3-3/4″ and width of 2-7/16″ plus nuts sized at 0.55″ outside diameter provide a robust clamping footprint. The clamps deliver strong load-bearing performance, with maximum effectiveness when used in pairs in double-strut configurations. Proper tightening and alignment are essential to achieve the intended stability for double-strut installations.
Buying Guide: Key Purchase Considerations for Window Clamps and Double Strut Systems
- Channel compatibility: Confirm the clamp supports the exact channel width and gauge (e.g., 13/16″, 1-5/8″, 2-1/4″ categories) used in your project.
- Load requirements: Determine whether you need single-clamp capacity or pair-based strength to achieve the desired system stability, especially for dynamic loads.
- Material and finish: Electro-galvanized or silver galvanized finishes offer corrosion resistance; consider environment exposure (indoor/outdoor, humidity).
- Fastening hardware: Verify thread size and bolt length (e.g., 3/8″-16, M10) to ensure compatibility with your strut channel and anchors.
- Ease of installation: Look for clamps with straightforward alignment and minimal assembly steps to reduce installation time.
- Durability and warranty: Consider the build quality (thickness, plate design) and any manufacturer guarantees for long-term reliability.
- Compatibility with conduits: If applying to electrical installations, ensure clamps accommodate rigid conduit and EMT as needed.
- Installation environment: For outdoor or humid environments, select corrosion-resistant options and plan for thermal expansion considerations.
