Cable Rack Hooks are steel support components that fit into T-slots of cable rack channels (T-Slot Channel, T-Section, and Nob-Loc styles) to organize and secure cables in manholes and underground vaults. Manufactured from 3/16-inch steel with hot-dip galvanization per ASTM A123/A153, these hooks resist corrosion in harsh underground environments. Standard lengths range from 4 to 18 inches (common sizes: 4, 7.5, 10, 14, and 18 inches) and fit T-slots spaced at 1-1/2 inch intervals.
The hooks provide secure mounting points with load ratings of 300 to 400 pounds when properly installed, handling significant cable weights in utility settings. Turned-up ends prevent cables and rack insulators from slipping off, while smooth surfaces and generous radius bends protect against cable damage. Installation involves inserting the hook base into T-slot channels and engaging a locking mechanism for secure attachment without complex tools.
Optional accessories include porcelain insulators, plastic T-slot clips, zinc locking clips, and variants with stainless steel or PVC coatings for enhanced protection. The hooks comply with ANSI C135.35 for utility hardware, meeting industry requirements for electric and communications cable installations in standardized rack systems.

Frequently Asked Questions (FAQS)
How do your cable rack hooks ensure long-term reliability for critical infrastructure projects?
RaxPower's cable rack hooks are manufactured from 3/16-inch high-strength steel and undergo hot-dip galvanization per ISO 1461 and ASTM A123/A153 standards, providing corrosion resistance for underground environments. They feature smooth surfaces with generous radius bends and turned-up ends to protect cables from abrasion, bending damage, and accidental displacement. Load rated to 300 pounds when properly installed, they ensure durability in grid maintenance and expansion projects.
What sizes are available for cable rack hooks?
Cable rack hooks are available in multiple standard lengths: 4 inches (102mm), 7.5 inches (190mm), 10 inches (254mm), 14 inches (356mm), and 18 inches (457mm). They are designed to fit into T-slots spaced at 1-1/2 inch intervals on various cable rack systems including T-Slot Channel, T-Section, and Nob-Loc styles. Custom sizes can be accommodated for specific project requirements.
How are cable rack hooks installed?
Cable rack hooks are installed by inserting the hook base into T-slots along cable rack channels at desired intervals. They feature a locking mechanism for secure attachment and can be mounted with 1/2″ or M12 bolts for stability in manholes and vaults.
What accessories are available for specialized applications?
RaxPower provides complementary accessories including porcelain insulators for electrical insulation, plastic T-slot rack hook clips, zinc locking clips for enhanced security, and optional PVC coatings for additional cable protection. Stainless steel and plastic-coated hook variants are also available for specialized telecommunications, power distribution, and industrial utility applications.
How should cable racks be spaced for optimal support?
Cable racks are typically mounted with bolt hole spacing of 13-1/2 inches for 8-hole racks, 22-1/2 inches for 14-hole racks, and 28-1/2 inches for 18-hole racks, allowing for organized cable routing and efficient support in manholes and vaults.
