Product Features
Advanced Three-Bolt Clamping System
The straight cable suspension clamp utilizes a robust three-bolt configuration where the 5/8" through-bolt serves dual purposes as both the mounting element and primary clamping member. This intelligent design distributes clamping forces evenly across the messenger strand, preventing stress concentration points that could lead to premature cable failure.
Corrosion-Resistant Construction
Manufactured from high-grade carbon steel with hot-dip galvanized coating meeting ASTM A153 standards, the straight cable suspension clamp delivers exceptional resistance to atmospheric corrosion, salt spray, and industrial pollutants. The galvanization process provides a minimum zinc coating thickness of 3.9 mils (100 microns), ensuring protection in coastal and industrial environments.
Tool-Free Strand Insertion
The open-design configuration allows linemen to position the messenger strand without removing the through-bolt, significantly reducing installation time and improving safety during overhead work operations. The straight cable suspension clamp design supports single-handed operation when properly secured to the pole structure.
Temperature Performance Range
Tested and certified for continuous operation from -40°C to +85°C (-40°F to +185°F), the straight cable suspension clamp maintains structural integrity and clamping force across the full temperature spectrum encountered in telecommunications infrastructure deployment.
Low-Profile Design
With a total length of only 5.75 inches (146mm) and width of 1.69 inches (43mm), the compact straight cable suspension clamp minimizes wind loading and visual impact while maintaining full structural performance. The streamlined profile reduces ice and snow accumulation in winter climates.
Standardized Mounting Interface
The 11/16" (17.46mm) center mounting hole accommodates standard 5/8" through-bolts with proper clearance for thermal expansion. This standardized interface ensures compatibility with existing pole hardware and simplifies inventory management for telecommunications contractors.
Factory-Installed Hardware Integration
All fastening components including carriage bolts (1/2"-13 thread), square nuts, lock washers, and through-bolts are pre-assembled at the factory. This eliminates the risk of missing components in the field and ensures proper hardware specifications are maintained throughout the installation process.
Optimized Grip Profile
The curved inner surfaces of the clamp body and keeper are precisely machined to match standard messenger strand profiles. This contoured design maximizes contact area while minimizing point loading on the cable, extending cable service life and maintaining optimal signal transmission characteristics for fiber optic applications.
