HPHPMSM Series J-Hook - Composite Wide Base Hook w Magnet - 10 pack by Doc's Industries Inc.

The HPHPMSM cable support provides a controlled overhead pathway for low-voltage cable bundles where sharp edges, narrow support surfaces, and inconsistent attachment methods can compromise a clean installation. Its 2-inch-wide, slick plastic base gives Cat 5e, Cat 6, Cat 6A, Cat 7, and fiber optic lines a smooth bearing surface, while the metal backbone and PM90 neodymium pot magnet create a heavy-duty structural anchor. Hook and Hanger supplies this cULus-listed, RoHS-compliant hardware for commercial cable management work where cable handling and pathway consistency matter.

Unlike a conventional all-metal hook, the hybrid support combines a burr-free composite cable-contact surface with a rigid steel member. Its preassembled magnetic base attaches directly to a suitable ferrous structure without drilling into building steel. We stock these components for contractors who need repeatable support spacing, a protected cable pathway, and a method suited to sensitive high-speed network installations.

What Is the HPHPMSM Cable Support Used For?

The HPHPMSM cable support is used to form a supported pathway below or alongside structural steel where communication cables must remain organized and protected. The magnet holds the assembly to steel beams, joists, and iron framework, allowing crews to position supports along the planned route before loading cable. This keeps bundles away from ceiling-grid components, sprinkler piping, ductwork, and services that should not carry data cabling.

Each support includes an integrated snap-lock retainer latch. Once the cable bundle is placed in the support, the latch closes over the opening to retain the run without separate wire loops, cable ties, or hook-and-loop wraps. The design reduces handling steps at elevation and helps prevent cables from escaping during pull-in or later service. Where installations have traditionally used narrow j-hooks, the broad support surface provides a more controlled route for category cable and fiber.

An industry-leading average bend radius of 3.57 inches allows the HPHPMSM cable support to guide bundles through direction changes without forcing the cable against a tight inside curve. Maintaining that radius reduces localized jacket pressure and helps protect conductor geometry, which is important for controlling crosstalk and preserving transmission performance. The support is TIA compliant for layouts requiring cable separation and future moves, adds, and changes.

What Are the HPHPMSM Cable Support Specifications?

The HPHPMSM cable support is available in two support diameters for different bundle sizes. Capacity values are based on a conservative 70% fill rate, and the stated load tolerances incorporate a 3-to-1 safety factor. The rated breakaway strength of the magnetic assembly is 90 pounds.

• HPH16: 1.07 sq. in. pathway 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 of 25; product weight of 3 lbs.

• HPH32: 3.97 sq. in. pathway 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 of 25; product weight of 4 lbs.

• Both configurations use a 2-inch-wide plastic base, a metal backbone, a PM90 neodymium-core pot magnet, and a snap-lock retainer latch.

• The supports are cULus listed, RoHS compliant, TIA compliant, and plenum rated for approved air-handling spaces.

How Does the HPHPMSM Cable Support Attach to Structure?

The HPHPMSM cable support arrives with the metal backbone preassembled to its high-strength neodymium-core pot magnet. The installer positions the magnet against a clean, suitable ferrous surface, verifies secure seating, and loads the cable route into the plastic base. This leaves the structural member intact and permits route adjustment before the cable bundle is installed.

• Attach directly to structural steel beams, joists, and iron frameworks that provide a clean magnetic contact surface.

• Use the PM90 pot magnet for tool-free, high-strength adhesion rather than drilling or adding separate mechanical hardware to the steel.

• Confirm the planned support spacing, cable weight, environmental conditions, and applicable project requirements before loading the pathway.

• For crews accustomed to overhead drilling and anchoring, the magnetic mounting method offers a fast, surface-protective alternative on suitable steel.

• Where an elevated work position is required, use appropriate access equipment or compatible extension poles in accordance with jobsite procedures and the tool manufacturer’s instructions.

A magnetic pathway is not a substitute for every structural attachment method. Nonferrous steel, painted or contaminated surfaces, curved surfaces, and locations subject to abnormal vibration require a project-specific review. Hook and Hanger supplies related attachment hardware, including angle clips, when the structure or pathway design calls for a mechanical support method instead.

Why Use Hybrid J-Hooks in Plenum Spaces?

The hybrid assembly is suited to commercial interiors where data cables pass above a suspended ceiling and through approved air-handling spaces. Its plenum-rated plastic cable-contact portion supports pathway requirements in those areas, while metal reinforcement maintains the rigid shape needed for overhead service. The smooth base also prevents cable bundles from resting directly on sharp metal edges that can abrade jackets during installation or maintenance.

Color options in white, red, blue, and black allow crews to identify different circuits, systems, project zones, or installation phases without changing the basic support method. That can simplify inspection, reduce routing confusion, and make later tracing more efficient. We offer bulk shipping through Hook and Hanger’s nationwide distribution process so purchasing teams can coordinate support quantities with cable-pull schedules and site delivery requirements.
