Choose the Support Around the Raceway or Cable
Support hardware keeps raceways and cable systems aligned and helps avoid transferring unnecessary stress to fittings and terminations. Start with the raceway or cable type, trade size or outside dimension, installed load, and the surface that will carry the support. Coordinate supports with the conduit fittings and connectors used in the run.
Match the Support Type and Mounting Surface
One-hole straps, two-hole straps, clips, brackets, channel or strut hardware, and specialty supports solve different mounting problems. Confirm the compatible raceway or cable size, mounting orientation, substrate, load, and fastener method on the exact product.
Coordinate Brackets, Channel, Anchors, and Fasteners
Wall, ceiling, and structural supports can require brackets, channel, threaded hardware, anchors, and bolts. Select anchors for the substrate and load, and coordinate screws and bolts with the support manufacturer's instructions.
Spacing Depends on the Wiring Method
Different conduit, raceway, and cable systems have different securing and support requirements. Use the applicable wiring-method rules and manufacturer instructions for the exact installation. Do not reuse a spacing value from a different product family just because the runs look similar.
Build a Repeatable Support Schedule
For larger projects, record support type, size, mounting method, spacing, hardware, material, and quantity by run. This helps prevent field substitutions that change capacity or environment suitability. For bundling and smaller cable-management tasks, compare cable ties and the broader hardware and fasteners range.
Straps and Supports FAQs
How far apart should conduit supports be?
The required spacing depends on the raceway type, size, installation, product instructions, and applicable electrical requirements.
Can I use any strap that fits around the conduit?
No. Confirm the support is intended for the wiring method, size, mounting surface, load, and environment.
Do outdoor supports need a special material?
Use material and finish suitable for the actual exposure, including moisture or corrosion conditions stated for the project.
