Description

SunModo SMR300 Rail 174″ Mill Finish SMR300-174-M

The SMR300-174-M is SunModo’s heavy-duty SMR300 extrusion in a 174″ (14.5 ft) length and mill finish. Engineered from 6005-T5 aluminum, the SMR300 profile (≈3.03″ H × 1.97″ W) provides high section strength for longer spans and demanding loads in SunModo SMR/SunTurf® assemblies.

Key Benefits

High-Strength Rail: Robust section properties (Sx ≈ 0.527 in³, Sy ≈ 0.303 in³) enable longer spans with fewer supports. 

Lightweight & Durable: 6005-T5 aluminum extrusion with mill finish; ~0.783 lb/ft unit weight for easy handling. 

System Compatible: Works with SMR300 splices, end caps, L-foot adapters, and pop-on clamps.

Special Technology

Optimized SMR Profile: Deep section and reinforced lips support clamp engagement and accessory mounting while maintaining low weight. 

Warranty

Manufacturer’s standard racking hardware warranty (SunModo).

Best Uses

Pitched Roof & Ground-Mount: Long-span rail runs, higher snow/wind regions, and SunTurf® frames needing stiffer rails.
