Heavy-Duty Duct Closure & Sealing Plug for Telecom, Fiber & Underground Utilities in Saudi Arabia & Gulf Region
Infrastructures modernization is taking place in KSA, as well as in the whole Gulf Cooperation Council (GCC), and among the sophisticated projects underground utilities are the main factor for successful delivery of power, telecommunications, fiber optics, and control systems. The mentioned utility networks have been sprawling through cities, industrial zones, and rural areas and it is becoming increasingly important to protect the duct ends during and after installation in maintenance.
The End Plug 110mm Jack Mount is specially made precision device that seals and closes 110mm diameter conduits, especially those which are mounted using jack methods or installed by directional drilling. It encloses the ducts with a strong and reliable seal which protects them from moisture, dust, debris, rodents, and environmental contaminants thus keeping the network intact before and after the cable installation.
The End Plug 110mm Jack Mount is a mechanical closure solution used to seal the open end of a 110mm duct or jack mount conduit. Its purpose is to protect the duct’s interior during staged construction, cable pulling, maintenance, or long-term service.
Designed to fit precisely within standard 110mm diameter conduits, the plug creates a tight, dust-proof, and moisture-resistant sealing interface. End plugs are essential in environments exposed to soil moisture, sand, corrosion, rodents, and construction debris — conditions frequently encountered in Gulf infrastructure projects.
Whether used in telecom, fiber optic, power cable, micro-duct, or utility corridor installations, the End Plug 110mm Jack Mount helps maintain conduit cleanliness and integrity throughout the lifecycle of the utility network.

The exposure of open conduit to the air and the environment makes the systems prone to:
However, installing a good quality end plug right after trenching, drilling, or jack mounting not only secures against these dangers but also guarantees that cable installation, fiber pulling, and network integrity go on without a hitch.

The End Plug 110mm Jack Mount is usually made of the durable and high-impact polymer plastics such as:
These are the materials chosen for the reason that they could resist tough, buried conditions along with temperature changes, chemical in soil, and mechanical impact.
Prepare the Duct End
Ensure the 110mm duct end is clean and smooth.
Inspect the Plug
Check that the plug matches the duct diameter and inspect for any defects.
Insert the Plug
Align the plug and press it into the duct until it is fully seated. Push-fit or locking mechanisms will secure it in place.
Verify the Seal
Confirm that the plug sits flush and creates a snug, sealed interface.
Backfill and Compact
After sealing, backfill the trench or hole per project specifications.
Re-Entry (If Required)
Some plug designs allow for removal prior to cable pulling and then reseating after installation.
Essential for sealing ducts during fiber deployment, especially in FTTH, FTTx, and backbone fiber networks.
Used to protect power cable conduits before and after pulling.
Provides organization and protection in shared utility trenches.
Commonly used in jack and bore methods to seal entry or exit pits.
Seals cable access points for industrial control and communications lines.
Secures conduit ends in sensor networks, urban networks, and digital utility grids
Seals conduits against intrusion of water, dust, sand, rust, rodents, and insects.
Facilitates smooth cable pulling operations by ensuring ducts are always clear.
Eliminates rework caused by duct contamination.
Increases the durability and functionality of underground systems.
Decreases repair, downtime, and maintenance costs of cables.
Push-fit variations are time and labor efficient.
Fast and tool-free mounting - perfect for the temporary and permanent installation.
Provide extra safety with a twist or lock mechanism that will keep the plug secured and prevent accidental removal.
Facilitate smooth re-access for cable pulls and network upgrades.
Suggested in areas where no future access is foreseen.
