Heavy-Duty Waterproof Closure for Telecom & Fiber Optic Ducting (KSA & GCC)
The Gulf region particularly Saudi Arabia, UAE, Qatar, Kuwait, Bahrain, and Oman is witnessing a phenomenal increase in telecom, fiber optic, and underground utility infrastructure. Development of underground ducting systems having the ability to withstand disasters is getting stronger with governments racing for 5G, FTTH connections, smart cities, metro rail communication, and power supply paths. HDPE corrugated ducts are the main material in KSA and GCC because of their flexibility, strong resistance against crushing, and long life.
The main reason for this performance is the duct joint sealing, protecting, and connecting the ducts that are the highest quality. A poorly sealed duct joint can let water in, allow sand to come in, and lead to the duct getting collapsed or fiber optic cable blowing getting interrupted at joint points. To eliminate such risks, the HDPE-Corrugated Duct 110mm Joint Closure is the solution and the contractors’ choice. This is a heavy-duty, weatherproof, and secure closure that has been specifically designed for 110mm OD HDPE corrugated ducts.
The HDPE-Corrugated Duct 110mm Joint Closure is a heavy-duty protective component designed to securely join two 110mm HDPE corrugated ducts used in telecom, fiber optic, and underground utility networks. Engineered from high-strength, UV-resistant polymer, this joint closure ensures a fully sealed, waterproof, and dustproof connection, protecting ducts from sand, moisture, soil pressure, and external impacts.
It provides excellent mechanical stability, maintaining duct alignment during cable blowing operations and ensuring low-friction pathways for fiber optic installation. The closure features a reinforced locking mechanism—either snap-lock or screw-tight—which guarantees long-term sealing performance even under harsh Gulf-region conditions such as extreme heat, humidity, and soil movement.
Suitable for 5G networks, FTTH rollouts, smart city projects, backbone telecom routes, electrical cable protection, metro communication channels, and industrial utility ducting, the 110mm Joint Closure delivers dependable performance for mission-critical underground installations. Its quick, tool-free or minimal-tool installation makes it ideal for fast-paced field deployments across KSA and the wider GCC infrastructure market.

The main objective is to create a safe, durable and totally matched connection between the two corrugated pipes applied in:
Telecom ducts experience harsh underground conditions such as:
Water accumulation
Soil movement
Vehicle load
Sand entry
Temperature variations (up to 55°C in summer)
If joints are not protected:
❌ Water may enter ducts
❌ Fiber blowing becomes impossible
❌ Cables may get damaged
❌ Duct life reduces significantly
❌ Sand and dust can choke sub-ducts
❌ Internal friction increases
A 110mm HDPE Joint Closure prevents all of these issues by ensuring:
✔ 100% sealed connection
✔ Safe cable blowing
✔ Smooth internal surface
✔ Long service life of ducts

A 110mm Joint Closure which is most common is made up of:
A plastic enclosure that is reinforced and serves as weather protection for the duct joint.
Makes sure the ends of the ducts are aligned perfectly so that there will be no problem for the cable to come in.
Water and dust proof seal is provided.
Fastening system of snap-lock or screw-tight type.
It is possible for the installers to grip and tighten without being in any danger.
Trim duct ends using a duct cutter to ensure straight edges.
The internal guide aligns ducts perfectly.
Snap or tighten screws to close.
Rubber seals prevent sand, dust, and water entry.
Smooth internal bore ensures low friction for fiber installation.
This joint closure is thereby applied to practically every project of underground utility and fiber ducting.
