Batwing J-Hook - High Performance Hybrid Metal / Plastic Composite Wide Base J-Hook with Batwing clip for Threaded Rod & Ceiling Wire Cable Support

Batwing J-Hooks for Cable Support

In large commercial buildings, there are often large numbers of low voltage cables routed throughout the building. The most effective way to do this is by hanging these cables from the roof structure, thus eliminating tripping hazards. It also keeps the infrastructure out of sight of the building's occupants, giving a sense of neatness and simplicity to the work environment. 

Suspending cables and wires in commercial buildings looks simple, but there are some key factors to bear in mind. Cables must often travel over long distances and in multiple directions, which can result in an untidy installation with safety and aesthetic problems. 

Without the proper cable support, cables can get damaged by crimping or bending too sharply. These faults may not always be readily visible, meaning that troubleshooting may take some time and prove costly. Disorganized cables are a safety risk. They can allow a buildup of heat, which could lead to a fire.

Cable management systems help alleviate these problems. They consist of cable supports that provide a means for organizing cables. Bigger buildings require more complex networking and cable infrastructure. But even small office environments have multiple cable runs in different directions to cover the office needs.

Cable trays are typical for installations with large numbers of cables. But they are cumbersome to make and install. They offer no flexibility to modify cable routings in the future.

J-Hooks are a great alternative to cable trays. Instead of a continuous structure, J-Hooks offer intermittent support at appropriate intervals. They give the required cable support but provide the flexibility for changing positions and routings. They are available in 3/4 inch to 4-inch sizes. The 4-inch option allows for heavy-duty installation of up to 300 4-pair UTP CAT 5e or 2-strand fiber optic cables.

Batwing J-Hooks are a specific type of cable support. They are versatile and easy to use, ideally suited for large commercial buildings.

Not all J-Hooks are created equal. Sharp edges can introduce cuts to cable insulation and eventually damage the cable itself. Inadequate curvature may put too much pressure on some cables leading to stress and crimping. The distance between supports and the number of cables resting in a J-Hook all have the potential to care for cable infrastructure or harm it.

The purpose of the batwing j-hook design

Batwing clips are designed to clip onto a vertical attachment without using a fastener, like a bolt or a strap. The primary attachments for batwing clips are suspended ceiling wires or threaded drop rods. Each end of the batwing clip connects to the ceiling wire or drop rod with the J-Hook bracket hanging from the clip. The force of gravity on the J-Hook presses the batwing bracket into the drop rod and prevents it from slipping or coming detached.

The benefits of preassembled j-hook with batwing

One advantage of the batwing J-Hook is that it can be attached to drop rods before they are attached to the roof structure. This preassembly makes the whole installation process much simpler. The installation process follows these simple steps:

Attach the batwing J-Hook to the drop rod
Install the drop rod onto the roof structure
Hang the cables in the J-Hook and secure them with the retention bracket.

Threaded drop rods are a common type of roof and ceiling attachment. They come in several different lengths and have many different fastener options for attachment. Drop rods fit directly onto concrete ceiling decks or bar joists. A full range of fasteners caters to any site peculiarities. J-Hooks with batwings can be preassembled to any threaded rod and fastener combination.

About High Performance Hybrid (HPH) J-Hooks

HPH J-Hooks are specially designed to provide optimum support for high speed data cable, such as Cat 5e, Cat 6, Cat 6A, Cat 7 and fiber optic.

We use a hybrid of metal and plastic components to offer the best of both worlds. The plastic component provides a two inch wide base support with a slick and burr free surface. The metal component provides a strong backbone. The combined J-Hook is UL listed, RoHS compliant, TIA compliant and is suitable for installation in plenum and air handling spaces.

One of the most innovative features of the HPH J-Hook is the built-in snap-lock retainer. This is far superior to clumsy retainer wires, cable ties or Velcro straps that require additional on-site installation.

Bend radius is an important factor in any high speed data cable installation. HPH J-Hooks offer the largest bend radius available at an average of 3.57 inches.

HPH J-Hooks are available pre-assembled to UL listed and RoHS compliant attachments, allowing for easy installation to a variety of structures and surfaces.

Consult with the cable manufacturer for proper installation guidelines.

The advantage of a hybrid solution

Many J-Hook brackets consist of a single material - either metal or plastic. Metal brackets are durable but can have sharp edges that press against cables. Plastic is smooth and burr-free but does not have the strength to hold large cable bundles.

HPH stands for High-Performance Hybrid because they consist of both plastic and metal. The combination of metal and plastic components in the HPH J-Hook gives the cable support both strength and smoothness. The two-inch-wide plastic base has a slick and burr-free surface for cables to rest on, while the metal component provides a strong backbone underneath. This hybrid design takes advantage of the benefits of each material while avoiding their negative characteristics.

The importance of bend radius 

High-speed data cables are designed for high-speed data transfer, but their performance can be negatively impacted during installation or by a poorly designed cable support system. Twisted pair cables rely on the precision with which the pairs are twisted together. Bending a twisted pair cable into a tight arc with a radius less than 1-inch changes the twisting geometry. This geometry change allows interference from other wires and affects the performance of the pair.

Fiber optic cables are even more sensitive. Bending into an arc with a radius less than 2 inches can cause micro-cracks in the cable or refraction losses, both of which affect the integrity of the signal. Fiber optic cables are becoming more common all the way to user stations. This makes the bend radius of J-Hooks with batwings even more critical. The bend radius should be configured to meet the minimum fiber requirements of 2 inches. 

HPH J-Hooks are specially designed to provide optimum support for high-speed data cables, such as Cat 5e, Cat 6, Cat 6A, Cat 7 and fiber optic cables. The large plastic base extends the bend radius of cables suspended from the support. Their smooth plastic edges also do not press against the cable like sharp metal edges can do. This eliminates the chance of cable kinks and the associated cable damage.

HPH J-Hooks offer the largest bend radius of any J-Hook bracket on the market at an average of 3.57 inches.

A superior retention system

One of the main factors contributing to the untidiness of the cable installation and the potential for cables to come loose is the retainer system. Retainer wires, cable ties, or velcro straps require onsite installation and are cumbersome to change when adding or removing cables. The snap-lock retainer on our J-Hooks with batwing clips resolves these issues with a simple one-touch latching mechanism. It is easy to apply and folds out of sight. The whole installation is neater and easier to manage.

Understanding compliance and certification

The Telecommunications Industry Association (TIA) sets standards for cable supports and installations. It is vital to use J-Hooks that meet the TIA standards - this will ensure that the bend radius of the cables is large enough to prevent cable damage. J-Hooks that are not TIA compliant may not present problems during installation but will impact cable integrity over time. 

All our attachments, like drop rods and the various fastener options, are UL listed, meaning that they have been tested and certified for quality and safety. They are suitable for installation in the plenum and air-handling spaces.

Our components are also RoHS compliant, which is the European standard for the restriction of hazardous substances. Using our J-Hooks with batwing clips gives our customers peace of mind regarding occupational health, safety, and quality.
