Installation Efficiency: Pre-punched holes eliminate on-site drilling, reducing labor time by 40% compared to unpunched channels.
Load Rating: 41×21mm channel supports 2,000 lbs when mounted vertically, suitable for heavy conduit banks.
Conduit Compatibility: Accommodates EMT, rigid metal, and PVC conduits using channel nuts and conduit clamps.
Fire Resistance: Uncoated steel achieves 1-hour fire rating in concealed spaces, meeting NEC Article 300 requirements.
Commercial Electrical Systems: Supports conduit runs in office ceilings, data centers, and retail storefronts.
Industrial Facilities: Installed in manufacturing plants to route power and control wiring, resisting mechanical damage.
Infrastructure Projects: Used in highway lighting poles and transit station electrical systems, withstanding outdoor exposure.
Q: What hardware is needed for installation?
A: Use 1/4-20 channel nuts with spring washers to secure conduit clamps, ensuring 80 ft-lbs torque for vibration resistance.
Q: Can these channels be cut to length?
A: Yes, use a reciprocating saw with a metal-cutting blade, then deburr edges to prevent injury and cable damage.
Q: Are they compatible with seismic bracing?
A: Yes, when paired with seismic clips (per ICC-ES AC136), they meet IBC seismic design categories A to D.
