Purpose of a 110mm Joint Closure

The main objective is to create a safe, durable and totally matched connection between the two corrugated pipes applied in:

  • Fiber optic ducting
  • Telecom main ducts
  • Power cable protection
  • Ducts for road crossings
  • Metro underground utilities

Importance of Joint Closures in Fiber & Telecom Infrastructure

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

Key Features

  • Compatible with the 110mm OD HDPE corrugated ducts
  • Strong, pressure-tight seal which seals are coming up
  • Resistance of UV light
  • Installation under the ground is allowed
  • The anti-slip rib profile ensures a very tight grip
  • Weatherproof and corrosion-free
  • Installation is very easy and no special tools are required
  • Smooth bore inside suitable for fiber blowing operations

Detailed Components of a Joint Closure

A 110mm Joint Closure which is most common is made up of:

🔹 Outer Closure Shell

A plastic enclosure that is reinforced and serves as weather protection for the duct joint.

🔹 Internal Alignment Guide

Makes sure the ends of the ducts are aligned perfectly so that there will be no problem for the cable to come in.

🔹 Sealing Gaskets

Water and dust proof seal is provided.

🔹 Locking Mechanism

Fastening system of snap-lock or screw-tight type.

🔹 Anti-Slip Surface

It is possible for the installers to grip and tighten without being in any danger.

How the 110mm Joint Closure Works

➤ Step 1: Prepare Duct Ends

Trim duct ends using a duct cutter to ensure straight edges.

➤ Step 2: Insert Ducts into the Closure

The internal guide aligns ducts perfectly.

➤ Step 3: Lock Closure

Snap or tighten screws to close.

➤ Step 4: Seal Protection

Rubber seals prevent sand, dust, and water entry.

➤ Step 5: Ready for Cable Blowing

Smooth internal bore ensures low friction for fiber installation.

Why This Product is Preferred in KSA & GCC Markets

The infrastructure of the Gulf region is faced with:

  • Heat that gets to 55°C at its peak
  • Dust storms
  • Very humid conditions at their highest
  • Ground with tough characteristics
  • Very thick and high-strength surfaces
  • The duct underground installation that is very deep and goes up to 110mm
  • The 110mm Joint Closure has been specially designed to withstand these harsh circumstances.

It is the choice of contractors from KSA and GCC due to the following benefits:

✔ Its durability is second to none
✔ It ensures ducts are completely sealed
✔ It is resistant to chemicals and corrosion in soil
✔ It prevents duct failure
✔ It offers fiber blowing efficiency
✔ It meets the duct standards of the GCC region

How to Install a 110mm HDPE Corrugated Duct Joint Closure (Step-by-Step)

1. Cut both duct ends straight

Use a 110mm duct cutter for a precise edge.

2. Insert the ducts into the closure shell

Position evenly on both sides.

3. Tighten or snap the closure

Ensure both sides are firmly locked.

4. Check the internal alignment

Smooth, circular alignment is important.

5. Test for sealing

Splash water or blow air to check for leakage.

6. Bury or secure the duct

Place it underground or inside manholes.

Maintenance Guidelines

In order to keep the best performance:

  • Cleaning the closure is mandatory during mounting
  • Keep the area around the seals spotless
  • Screws should not be tightened more than necessary
  • Often check the closures that are exposed
  • Damaged closures should be replaced without delay
