HPHFM24 Series J-Hook - Composite Wide Base Hook with knock-on spring steel beam clamp for flanges 1/8 - 1/4" thick, swivels 360° by Doc's Industries Inc.

The HPHFM24 cable support is a hybrid plastic-and-metal component for routing low-voltage cabling above finished ceilings and along structural steel. Its smooth, 2-inch-wide plastic base supports the bundle, while a high-strength metal backbone terminates in a pre-assembled knock-on spring steel beam clamp. Hook and Hanger supplies this configuration for cable management work that requires a broad cable surface and a heavy-duty structural anchor.

Designed for Cat 5e, Cat 6, Cat 6A, Cat 7, and fiber optic lines, the HPHFM24 cable support provides an organized pathway without placing sensitive jackets against a narrow steel edge. It is cULus listed, TIA compliant, and RoHS compliant, with a plenum-rated plastic component for applicable air-handling spaces. As a specialist distributor, Hook and Hanger stocks these components for contractors and purchasing teams that need practical overhead pathway hardware.

What Is the HPHFM24 Cable Support Used For?

This HPHFM24 cable support creates a controlled route for communications cabling in commercial, institutional, and data-focused interiors. It is commonly installed above a suspended ceiling, where pathways must stay accessible, orderly, and separated from other building systems. The smooth plastic loop distributes the bundle across a wider contact area than a narrow steel hook, helping protect cable jackets and preserve the path needed for high-speed data infrastructure.

An integrated snap-lock retainer latch closes over the bundle. This removes the need to field-install wire loops, cable ties, or hook-and-loop wraps merely to contain conductors. The latch can be opened for additions or changes, then snapped shut again. With an average bend radius of 3.57 inches, the HPHFM24 cable support reduces tight turns that can place strain on cable construction and contribute to signal degradation. This matters where multiple Cat 6A or fiber lines must transition through a compact ceiling zone.

For projects using several pathway support types, j-hooks can be selected by bundle size, route direction, and attachment point. This flange-mounted configuration should be spaced and loaded according to the installation plan, applicable codes, and cable manufacturer guidance.

What Are the HPHFM24 Cable Support Specifications?

The HPHFM24 cable support is available in four support diameters. Capacity figures are based on a conservative 70% fill rate and include a 3-to-1 safety factor on load tolerances.

• HPH16FM24: 1.07 in² 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.

• HPH32FM24: 3.97 in² area; 2-inch diameter; capacity for 90 Cat 5e, 60 Cat 6, or 35 Cat 6A cables; UL load rating of 20 lbs (88.96 N); package quantity 25; weight 6 lbs.

• HPH48FM24: 9.26 in² 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.

• HPH64FM24: 15.48 in² area; 4-inch diameter; capacity for 330 Cat 5e, 220 Cat 6, or 140 Cat 6A cables; UL load rating of 20 lbs (88.96 N); package quantity 25; weight 12 lbs.

Select diameter from the expected cable count, cable type, fill allowance, and future expansion needs. The same sizing method can be used alongside related structural hardware such as purlin clips where the application calls for that attachment method.

How Does the HPHFM24 Cable Support Attach to Structure?

The metal backbone is supplied pre-assembled to a knock-on spring steel beam clamp. It is designed for direct installation on structural steel without drilling or threaded fastening at the support point.

• The spring steel beam clamp grips flanges measuring 1/8 inch to 1/4 inch thick.

• It secures directly to structural steel frameworks, beams, and columns with a controlled hammer strike.

• Its integrated swivel connection permits 360-degree rotation, allowing the hook opening to align with pathway changes.

• The pre-assembled clamp reduces loose parts crews handle at elevation.

• Use beam clamps where flange dimensions, loading conditions, and project requirements match the attachment design.

This HPHFM24 cable support is suitable when the route can be supported from a compatible steel flange. Where attachment conditions differ, review angle clips for applicable structural layouts or eye lag screws for suitable wood attachment points. For concrete, deck, or other locations requiring a separate procedure, use approved overhead drilling and anchoring practices and verify the load path before installation. Appropriate extension poles can help crews reach approved overhead hardware from the floor.

Why Use Hybrid J-Hooks in Plenum Spaces?

In commercial interiors, plenum pathways need supports that suit the air-handling environment as well as the cable installation. The HPHFM24 cable support uses a plenum-rated plastic base paired with a rigid metal backbone that transfers load to the beam clamp. Its burr-free surface reduces jacket abrasion during placement, while the latch retains the bundle without adding tie material around the cables.

Red, blue, and black color options help identify pathways, circuits, tenant zones, or installation phases. This can simplify inspection, tracing, and later changes in a crowded ceiling area. We offer bulk shipping nationwide so contractors can coordinate material delivery with project schedules. Hook and Hanger also supplies threaded rod fasteners for applications using rod-supported hardware, where the specified attachment method calls for them.
