HPHHOK58 Series J-Hook - Composite Wide Base Hook with knock-on spring steel beam clamp for flanges 5/16 - 1/2" thick by Doc's Industries Inc.

The HPHHOK58 cable support uses a hybrid plastic-and-metal layout for routing low-voltage communications cabling from structural steel. A smooth, burr-free 2-inch-wide plastic base carries the cable bundle, while a rigid metal backbone transfers the load to a pre-assembled knock-on spring steel beam clamp. As a specialist distributor, Hook and Hanger supplies this hardware for practical cable management work where installers need a wide cable path and a heavy-duty structural anchor in one assembly.

These components are designed for sensitive Cat 5e, Cat 6, Cat 6A, Cat 7, and fiber-optic networks. The HPHHOK58 cable support is cULus listed and RoHS compliant, with a plenum-rated plastic support surface suited to air-handling areas. Its smooth base reduces jacket contact with metal edges, while the clamp provides a direct attachment point on qualifying steel flanges.

What Is the HPHHOK58 Cable Support Used For?

The HPHHOK58 cable support creates a supported pathway for communications cable above a suspended ceiling in commercial structured-cabling installations. Unlike narrow hooks that concentrate the bundle at a small contact point, its 2-inch-wide plastic cradle distributes the cable over a broader area.

An integrated snap-lock retainer latch holds the bundle within the support without separate wire loops, cable ties, or hook-and-loop wraps. It keeps the pathway closed after cable placement. The HPHHOK58 cable support provides a 3.57-inch average bend radius, helping eliminate constricting bend points that can strain conductors, deform jackets, and contribute to signal degradation in high-speed copper and fiber lines. It provides the controlled support profile required from properly specified j-hooks while adding a pre-attached structural connection.

What Are the HPHHOK58 Cable Support Specifications?

We stock the HPHHOK58 cable support in four support diameters so the pathway can be sized to the estimated cable fill and the available overhead clearance. The following capacities are calculated at a conservative 70% fill rate and include a 3-to-1 safety factor on load tolerances.

• HPH16HOK58: 1.07 sq. in. support area; 1-inch diameter; capacity for 20 Cat 5e, 15 Cat 6, or 10 Cat 6A cables; UL load rating of 20 lbs. (88.96 N); package quantity 25; weight 4 lbs.

• HPH32HOK58: 3.97 sq. in. support area; 2-inch diameter; capacity for 90 Cat 5e, 60 Cat 6, or 35 Cat 6A cables; UL load rating of 17 lbs. (75.62 N); package quantity 25; weight 5 lbs.

• HPH48HOK58: 9.26 sq. in. support area; 3-inch diameter; capacity for 200 Cat 5e, 150 Cat 6, or 80 Cat 6A cables; UL load rating of 20 lbs. (88.96 N); package quantity 25; weight 10 lbs.

• HPH64HOK58: 15.48 sq. in. support area; 4-inch diameter; capacity for 330 Cat 5e, 220 Cat 6, or 140 Cat 6A cables; UL load rating of 17 lbs. (75.62 N); package quantity 25; weight 12 lbs.

The HPHHOK58 cable support should be selected by cable count, cable outside diameter, pathway changes, and the load rating for the specific size. Do not pack the support beyond its stated planning capacity or use the listed cable counts as a substitute for a pathway design review.

How Does the HPHHOK58 Cable Support Attach to Structure?

The metal backbone is pre-assembled to a knock-on-style spring steel beam clamp for flanges measuring 5/16 inch to 1/2 inch thick. The installer positions the clamp on the appropriate steel member and applies a hammer strike to seat it. This approach removes the need to drill the steel for the connection when the flange thickness and installation conditions meet the clamp requirements.

• Attach directly to qualifying structural-steel frameworks, beams, and columns with the pre-assembled clamp and a controlled hammer strike.

• Use the integrated swivel connection to rotate the HPHHOK58 cable support through 360 degrees and align the cradle with the cable path rather than forcing the bundle into an incorrect approach angle.

• Confirm flange thickness, structural condition, clearance, loading, and project requirements before installation. For other attachment methods, our overhead drilling and anchoring hardware and extension poles support separate overhead installation workflows.

• Use beam clamps, angle clips, purlin clips, or eye lag screws only where their individual structural application and manufacturer instructions apply; they are alternative support approaches, not replacements for the pre-assembled knock-on clamp.

Hook and Hanger supplies the system as a direct steel-flange support method, helping crews establish an orderly pathway without adding separate attachment hardware to each cable cradle.

Why Use Hybrid J-Hooks in Plenum Spaces?

The HPHHOK58 cable support is intended for plenum-rated pathway work in air-handling spaces, including overhead areas above ceilings where material selection and cable support practices must meet project documentation. Its plastic base is smooth and plenum-rated, while the metal backbone and spring steel clamp maintain the structural load path. The product is also TIA compliant, supporting a managed cable route that keeps communications lines off ceiling grid, piping, and other building systems.

Color options in red, blue, and black help installation teams identify pathways by circuit, system, tenant, or phase. This can simplify inspection and later service work when multiple communications routes share the same overhead zone. We offer packaged quantities suited to staged installation and nationwide shipping, while Hook and Hanger can help purchasing teams match the required diameter, color, and support count to the project scope.
