ADSS J-Hook Suspension Clamp HC-10-15/HC-15-20 Price in Kenya

The ADSS J-Hook Suspension Clamp HC-10-15/HC-15-20 is an aerial fibre installation accessory used to support All-Dielectric Self-Supporting (ADSS) fibre optic cable at intermediate poles along an overhead fibre route. It supports the cable without turning the intermediate pole into a full tension or dead-end point.

The two common versions cover different cable diameters: HC-10-15 for 10–15mm ADSS cable and HC-15-20 for 15–20mm ADSS cable. Typical designs combine a galvanized-steel J-shaped body with a UV-resistant elastomer or neoprene insert that cushions the cable and helps distribute mechanical pressure without damaging the fibre jacket. 

These clamps are especially useful in ISP, telecom and backbone aerial fibre projects where ADSS cable runs across utility or telecom poles and requires controlled support between anchor points.

Key Specifications

A widely published HC-series specification lists the body as galvanized steel, the insert as UV-protected neoprene, and the fixing screw as protected steel. 

What Is a J-Hook Suspension Clamp?

A J-Hook Suspension Clamp is designed to support an aerial fibre cable at an intermediate pole while allowing the cable to continue along the route.

A typical aerial configuration is:

Anchor Clamp → ADSS Cable → J-Hook Suspension Clamp → ADSS Cable → J-Hook Suspension Clamp → Anchor Clamp

The J-hook supports the cable's weight and helps maintain the intended sag between poles.

HC-10-15 Cable Range

The HC-10-15 version is designed for round ADSS fibre cables with an outside diameter of approximately:

10mm to 15mm

This makes it suitable for many medium-sized access and distribution ADSS cables.

HC-15-20 Cable Range

The HC-15-20 is designed for larger ADSS cables between:

15mm and 20mm

It is suitable where higher-core-count or more heavily constructed ADSS cable has a larger outside diameter. 

Protective Rubber or Neoprene Insert

A major part of the clamp is the protective insert that surrounds the fibre cable.

Its role is to:

• Cushion the ADSS jacket

• Reduce point loading

• Prevent metal-to-cable contact

• Improve cable grip

• Reduce vibration damage

• Protect against abrasion

The HC-series is commonly specified with UV-protected neoprene or elastomer cable inserts. 

Galvanized-Steel J-Hook Body

The J-shaped body is normally manufactured from galvanized steel.

Galvanizing helps improve resistance to:

• Rain

• Humidity

• Outdoor corrosion

• Long-term weather exposure

The J shape also allows the ADSS cable to be routed into the clamp conveniently before the closure bolt is tightened.

Bolt Closure System

The clamp normally uses a bolt and nut to close the elastomer insert around the cable.

A typical field installation can be completed using a standard 13mm spanner on many HC-style clamps. 

This makes the clamp simple to install using ordinary field tools.

Pole Mounting Methods

The J-Hook clamp can be mounted to poles in several ways.

Stainless-Steel Banding

The clamp can be fixed using:

Pole → Stainless-Steel Band → J-Hook Clamp

This method is particularly useful on concrete and steel utility poles.

Pole Bolt

Where the pole allows bolted mounting, the clamp can be secured directly through the mounting hole.

Pigtail Hook

The clamp can also be mounted using compatible pigtail hooks or brackets, providing a more flexible suspension point and helping reduce vibration transmitted to the cable. 

ADSS J-Hook Clamp with BAND-IT Banding

For concrete poles, a typical installation can be:

Concrete Pole → BAND-IT Stainless-Steel Strap → J-Hook Clamp → ADSS Cable

This provides a practical mounting method without drilling the pole.

A BAND-IT or equivalent stainless-steel banding tool can be used to tension and secure the strap.

What Is ADSS Fibre Cable?

ADSS stands for All-Dielectric Self-Supporting.

ADSS fibre is designed for aerial installation without requiring a separate steel messenger wire.

Advantages include:

• No metallic conductor

• Lightweight construction

• Electrical isolation

• Suitable for utility infrastructure

• Self-supporting aerial spans

• High fibre capacity

Because the cable supports its own mechanical load, the correct suspension and tension hardware is essential.

Suspension Clamp vs Tension Clamp

The two components are used together on an aerial route but serve different mechanical roles.

Where Should J-Hook Suspension Clamps Be Used?

J-hook suspension clamps are primarily installed at intermediate poles on relatively straight cable routes.

One HC-style specification states that they are intended for access networks with route angles below approximately 20° and spans up to around 100m, depending on the complete cable and network design.

For sharp turns or dead-end points, an appropriate tension or anchor clamp should be used instead.

Short-Span ADSS Networks

The HC-series is particularly common in short-span access networks.

Applications include:

• FTTH feeder fibre

• ISP distribution links

• Estate fibre networks

• Urban aerial fibre

• Rural ISP fibre

• CCTV backbone fibre

• Campus networks

Mechanical Strength

Some comparable HC/PT-style ADSS suspension clamps are rated with breaking loads around 12kN for both 10–15mm and 15–20mm cable sizes.

However, breaking load varies by manufacturer, so installers should always use the rating provided for the exact clamp supplied rather than assuming every HC-labelled product has identical mechanical performance.

ADSS Cable Route Example

A typical overhead fibre route can look like:

POP → ODF → ADSS Cable → Anchor Clamp → Pole → J-Hook → Pole → J-Hook → Pole → Anchor Clamp → Fibre Closure / Distribution Point

The J-hooks support the cable at intermediate poles while tension clamps secure the route at terminal or major directional points.

The ADSS J-Hook Suspension Clamp is especially important because ADSS fibre must be supported correctly throughout an aerial route. Allowing the cable to rest directly on pole hardware or using improvised supports can concentrate stress on the cable jacket and shorten its service life.

The elastomer-lined J-hook provides a larger, softer support surface for the cable while the galvanized frame carries the mechanical load. This combination helps protect the fibre jacket while maintaining the designed cable sag between anchor points. 

For complete aerial fibre projects, Fiber Optics Kenya can supply the J-hook clamps alongside ADSS cable, tension clamps, stainless-steel band, BAND-IT tools, pole brackets, fibre closures and other aerial fibre accessories.

HC-10-15 vs HC-15-20

The correct model is chosen mainly according to the outside diameter of the ADSS fibre cable.

Why Correct Clamp Size Matters

Using a clamp that is too small can:

• Compress the cable

• Damage the outer jacket

• Create optical stress

• Prevent correct closure

Using one that is too large can:

• Allow cable movement

• Reduce support

• Cause abrasion

• Affect cable sag

Always measure or confirm the cable's outside diameter before selecting the clamp.

ADSS Suspension Clamp Installation

A typical installation procedure is:

1. Confirm the ADSS cable diameter.

2. Select HC-10-15 or HC-15-20.

3. Install the clamp on the pole using a bolt, hook or stainless-steel band.

4. Open the clamp bolt.

5. Separate or open the protective insert.

6. Position the ADSS cable inside the insert.

7. Confirm that the cable is seated correctly.

8. Close the clamp.

9. Tighten the bolt using the recommended torque.

10. Verify cable sag.

11. Confirm that the cable is not excessively compressed.

12. Inspect the installation.

Installing with Stainless-Steel Banding

A typical concrete-pole installation is:

1. Position the J-hook against the pole.

2. Pass stainless-steel band through the mounting slot.

3. Wrap the band around the pole.

4. Install the buckle.

5. Tension the band with a banding tool.

6. Secure and cut the band.

7. Place the ADSS cable inside the clamp.

8. Close the clamp bolt.

9. Verify alignment.

Wind-Induced Vibration Protection

Aerial cables move due to wind.

Using a proper suspension clamp helps reduce localized mechanical stress caused by:

• Aeolian vibration

• Cable oscillation

• Wind loading

• Repeated movement

Installing the clamp on a hook bolt can also provide a degree of flexible suspension that further reduces vibration loading.
