J-Hooks | 048-140s Series

VERTICAL CABLE 048-140s SERIES – J-HOOKS (0.75 IN | 2 IN | 4 IN)

The 048-140s Series J-Hooks are rugged, galvanized steel supports designed for structured cable routing in commercial and industrial environments. With reliable strength and corrosion resistance, these J-Hooks offer an effective alternative to conduit and other rigid raceway solutions. Use them to neatly secure copper, fiber, coax, or combo bundles across ceilings, beams, or walls.

These hooks are easy to install, scalable, and compliant with performance standards for low-voltage pathways. Ideal for voice, data, video, and security applications.

  • 048-142/40 (4 in.): 0.44 lb (0.20 kg)
• Space-Saving Profiles:
  • Height ranges from 3.10 in. (78.8 mm) to 7.01 in. (178 mm)
  • Widths range from 0.87 in. (22 mm) to 1.93 in. (49 mm)

MECHANICAL CAPACITY

NOTE: The capacity chart provided above shows maximum possible values calculated based on the geometry parameters of the J-hooks. In real life installations, due to imperfection of cable bundles and variable paths cables take within the bundles, actual J-hook’s capacity could be lower and reach 50 % of the maximum as the worst-case scenario, the uncertainty grows as the number of cables placed on the J-hook grows. Typical recommended quantity reduction should be 25 % against the values provided in the graphs.

Additional limitations on discrete support load and capacity established by codes and standards:

1. For all power and power-limited cables, please, refer to the requirements set up in NFPA 70, National Electrical Code (NEC).
2. For all twisted-pair and optical fiber cables, follow the following guidelines set up by TIA and BICSI standards and manuals:

BICSI ITSIMM 8th Ed.:

• • • Open-top cable supports (e.g., J-hooks) … should not be used for installations of more than 50 cables. Do not overload open-top cable supports by using plastic cable ties to retain additional cables. Open-top cable supports should be attached to the building structure and installed on a center spacing varying between ≈1.2 m (4 ft) to ≈1.5 m (5 ft). These cable supports shall not be painted nor used for purposes not intended. Where not specified by the AHJ, open-top cable supports should be installed to maintain a minimum of ≈75 mm (3 in) vertical clearance between the cabling and cable supports and elements such as ceiling tiles, electrical conduit, luminaires, and piping and ducting. Open-top cable supports shall not be attached to a ceiling grid support system but may require a secondary connection to the ceiling grid to prevent lateral movement of the supports. No single support device should exceed the manufacturer’s recommended load rating, and the pulling tension used for placing a cable should not exceed the manufacturer’s recommendations.

BICSI TDMM 13th Ed.:

• • • For large quantities of cables (50 or more), provide cable trays or other special supports that are specifically designed to support the required cable weight and volume.

ANSI/TIA-569-E:

• • • Non-continuous supports shall be located at intervals not to exceed 1.5 m (5 ft).

TIA TSB-184-A:

• • • When installing PoE systems, calculate number of cables in a bundle per TIA TSB-184-A specifications; if calculations are not available, it is recommended to limit the number of cables per bundle to 24.

APPLICATIONS

The 048-140s Series is designed for environments where organization, airflow, and scalability are critical. Use them in:

• Data Centers: Maintain bend radius for fiber or CAT cables while supporting heavy bundles.
• Office Buildings: Route network or voice cabling across ceiling spaces and along walls.
• Industrial Facilities: Suspend communication lines or sensor wiring away from mechanical hazards.
• Retail and Commercial Spaces: Create clean, non-intrusive wire paths across display ceilings.
• Security Installations: Support camera and alarm cabling in multi-floor environments.

WHY CHOOSE THE 048-140s SERIES J-HOOKS?

Here’s why professionals choose this series:

1. Versatile Support Solution: Compatible with fiber, coaxial, twisted pair, and multi-bundle cable types.
2. Fast, Tool-Free Installation: Mounts easily with screws or bolts—no special hardware required.
3. Built for Harsh Environments: Galvanized finish resists rust in commercial and industrial applications.
4. Multiple Size Options: Available in three widths for custom cable density needs.
5. Load-Tested and Reliable: Designed to meet real-world cable support standards with safety margins in mind.

WHAT’S NEXT?

After selecting your 048-140s Series J-Hooks:

• Plan Your Pathways – Combine hook sizes to match cable loads and space constraints.
• Add Cable Labels – Ensure easy identification and maintenance.
• Bundle Smartly – Use hook-and-loop straps to keep cables neat within the hooks.
• Maintain Compliance – Follow TIA and BICSI best practices for spacing and support.
• Expand As Needed – Scalable installation lets you add more hooks as networks grow.
