JHACFM24 J-Hook with Rotating Knock-on Beam Clamp

The JHACFM24 J-Hook includes a galvanized steel cable support, a 90-degree angle clip, and an FM24 spring steel knock-on beam clamp. This assembled configuration provides a direct attachment point on structural steel and rotates through 360 degrees, allowing installers to align the support with the planned cable pathway. Hook and Hanger distributes this assembly for efficient cable management in commercial, institutional, and industrial interiors.

These components are optimized for all data comm and low-voltage cables, including CAT 5e, CAT 6, and fiber optics. The JHACFM24 J-Hook provides a heavy-duty structural anchor that is cULus listed, patented, and Plenum-rated, supporting compliant pathway installation without requiring a separate fixed mounting bracket.

What Is the JHACFM24 J-Hook Used For?

The assembly gives datacom crews a fast method for securing cable runs to accessible steel flanges while maintaining control over route direction.

• The integrated 90-degree angle clip and FM24 spring steel knock-on beam clamp create a complete attachment assembly, reducing the number of separate components crews must select and connect at each support point.

• A 360-degree swivel lets the installer orient the hook with the intended cable path, including route changes around ducts, conduit, and other overhead building systems.

• The wide, rounded J-Hook supports high-speed data and low-voltage cable without the tight pressure points associated with narrow or improvised supports.

• Four hook sizes accommodate different pathway volumes in offices, schools, healthcare facilities, warehouses, data rooms, and other commercial environments. This size range helps crews follow planned fill limits and maintain orderly cable distribution.

What Are the JHACFM24 J-Hook Specifications?

Each available JHACFM24 size has a defined working load and cable support capacity, allowing installers to match the hardware to the planned pathway.

• JH-12ACFM24 has a 3/4-inch hook size, a 17 lb. load capacity, and space for 16 CAT 5e/2-strand fiber optic cables or 10 CAT 6 cables.

• JH-21ACFM24 has a 1 5/16-inch hook size, a 17 lb. load capacity, and space for 50 CAT 5e/2-strand fiber optic cables or 32 CAT 6 cables.

• JH-32ACFM24 has a 2-inch hook size, a 17 lb. load capacity, and space for 80 CAT 5e/2-strand fiber optic cables or 50 CAT 6 cables.

• JH-64ACFM24 has a 4-inch hook size, a 50 lb. load capacity, and space for 300 CAT 5e/2-strand fiber optic cables or 185 CAT 6 cables.

• The assembly includes a galvanized steel J-Hook, a 90-degree angle clip, and an FM24 spring steel knock-on beam clamp with a yellow zinc chromate finish. It has a patented design and is assembled in the USA with global components. Separate model identifiers simplify size selection, packaging organization, and field distribution.

How Does the JHACFM24 J-Hook Attach to Overhead Structure?

The FM24 spring steel knock-on beam clamp grips the edge of a compatible steel flange, while the connected 90-degree angle clip positions the J-Hook for overhead cable support. Together, these components allow the support to rotate through 360 degrees for alignment with the intended cable route. Crews can install the structural attachments first, then rotate each support during final pathway alignment before placing the cable.

For crews comparing the assembly with standard overhead drilling and anchoring methods, the knock-on connection removes the drilling step at suitable flange locations. It also provides superior routing flexibility compared with a fixed mount. We supply beam clamps and angle clips for other structural conditions, allowing the attachment method to be selected according to the available steel, pathway alignment, and project drawings.

Why Use JHACFM24 J-Hook Supports in Plenum Spaces?

The JHACFM24 J-Hook is plenum-rated for installation in air-handling spaces, where component selection must account for building and fire-safety requirements. Its metal construction is suited to pathways above a suspended ceiling, and its cULus listing supports product verification during submittal and inspection review. NEC and TIA compliance also aligns the support with recognized requirements for structured cabling systems.

Hook and Hanger stocks compatible purlin clips, j-hooks, extension poles, eye lag screws, and threaded rod fasteners for projects involving multiple deck and structural conditions. This selection helps installers maintain consistent cable support practices across steel flanges, purlins, ceilings, and threaded-rod assemblies. The rotating design remains especially useful where a fixed support would place the hook out of alignment with the approved cable route.
