Plastic Spacer 20 mm 8 Way Base

Plastic Spacer 20 mm 8-Way Base

Multi-Duct Support for Telecom & Utility Trench Installations in KSA & Gulf

The Kingdom of Saudi Arabia and the Gulf states are facing challenges with the support systems for cable ducting as they have to cope with the rapid growth of their telecom networks, underground utilities, and data-centre infrastructures. One of the most significant but often ignored elements is the support of duct banks by the spacers. The Plastic Spacer 20 mm 8-Way Base plays a vital role in the maintenance of underground trenches and manholes. This base-type spacer continually supports eight ducts at a set distance of 20 mm between their core centers and gives a strong flat surface that guarantees the correct shape, makes installation easy, and renders the duct systems more durable through good performance. The spacer is made of high-quality plastic materials, which including UV-stable polypropylene, that can withstand the extreme desert weather, coastal salt, heavy civil works, and infrastructure deployments in Saudi Arabia and the GCC.

By the time you mention this spacer in the initial stage of your project drawings or procurement list, you ensure the correct alignment of the duct bundles, the best performance of the back-filled coatings and the least problems in future cable pulls or upgrades. The Plastic Spacer 20 mm 8-Way Base is ideal for medium to high-density duct banks in all types of applications, such as fibre-optic micro-duct deployments or power cable installations, in solar farms and large telecommunication hubs. Moreover, it is very durable and cost-effective, thus making it quite flexible for contractors, project managers, and procurement teams in the Gulf region.

The 20 mm 8-Way Base Plastic Spacer is a specially designed unit that acts as a base support for the first layer of ducts in a trench or manhole. It has eight arms or channels that make it possible to place eight conduits or micro-ducts side by side at a distance of 20 mm from each other. This ensures proper separation and alignment of the ducts. The strong base plate not only supports but also lessens the chance of the duct being moved under backfill and provides a plane for the next cable pulling operation.

The spacer is generally made from UV-stabilised polypropylene or some other engineering polymer. Not only is it non-corrosive, but also lightweight, easy to handle, and permissible to be used in underground utility runs, usually along with HDPE or PVC conduits. Its construction suggests very ably the hot Arabian desert, Gulf salty air regions, and big infrastructure traffic areas, thereby giving it a long life and little maintenance cost.

Typically, the spacer’s base is spaced 1 meter apart or according to instructions along the trench. After the eight ducts are positioned in the spacer arms, intermediate and top spacers may be used on top for multi-layer bundling followed by sand bedding and backfilling. This keeps the ducts uniformly supported, allows them to keep their shape during installation and commissioning, and guarantees their reliable operation in telecom, power, data-center, and industrial utility applications.

Material Composition & Manufacturing

The Plastic Spacer 20 mm 8-Way Base is made through the process of injection molding which involves the use of high-precision tooling to maintain the dimensional accuracy and uniformity of the channel spacing. The material that is chosen for this purpose is usually first-class polypropylene (PP) which is then mixed with UV stabilizers, antioxidants, and impact modifiers to guarantee a reliable performance in the Gulf region — high solar radiation, desert sand abrasion, salt-laden coastal air, and large-scale civil deployment cannot affect their performance.

The industrial processes involved are:

Compounding the polymer with the required additives.
Molding the base-plate which has the eight arms/channels formed of one piece that ensures the strength of the load by injection molding.
Cooling, removing, trimming of the flash, and the quality control for arm geometry and spacing.
Marking and packaging for the supply to infrastructure projects.
The use of plastic spacers instead of traditional metal or concrete ones has several advantages: they do not rust, they are light (hence lower logistic and handling costs), they are non-conductive (an important factor for electrical/telecom trenches), and they have a lower unit cost in large volume installations.

Applications in KSA & Gulf Region

Telecom & Fibre-Optic Infrastructure

In the GCC region, telecom providers are rolling out FTTH (fibre-to-the-home) and backbone micro-duct networks. The 20 mm 8-Way Base spacer allows multi-duct bundles (eight micro-ducts or HDPE conduits) to sit in precise alignment, ensuring efficient cable blowing and minimal friction losses. Used in trench and manhole installations by contractors servicing Riyadh, Jeddah, Dubai, Doha and Muscat.

Power and Electrical Utility Works

For medium-voltage cable runs or multiple conduits for instrumentation and power cables, consistent spacing and stable support matter. The spacer supports eight runs at once, making it well suited for high-density installations, electrical substation cable trenches or duct banks beneath major infrastructure.

Civil Infrastructure & Data Centres

High-density data-centre, metro, airport and smart-city projects in the Gulf region require reliable duct bank construction. The 8-Way base spacer facilitates organized conduit layouts, simplifies inspection and maintenance and supports future proofing for upgrades.

Renewable Energy Installations

Solar farms and wind-farm facilities often demand multiple parallel cable ducts. The spacer ensures eight conduits from an inverter or junction box stay aligned and protected on the substrate, aiding fast installation and long-term durability.

Industrial, Oil & Gas Facilities

In GCC oil-&-gas and petrochemical complexes, utility ducts for instrumentation, control cables and communication networks often require precise duct bank support in aggressive environments. The plastic spacer offers corrosion resistance and long service performance.

How to Use the Plastic Spacer 20 mm 8-Way Base

Installation Guide

Trench Preparation: Make the trench floor or manhole evenly compacted and smooth. Remove sharp objects.
Placement of Base Spacers: Place the 20 mm Base spacers 8-Way according to the spacing given in the project (generally 1.0 m apart).
Insert the first Duct Layer: Put 8 conduits or micro-ducts in the base spacer arm/channel while verifying the proper orientation and sitting.
Backfill or Install Additional Spacers: For multi-layer installation, after the first layer, intermediate spacers are to be placed before the next layer of ducts.
Secure and Align: Confirm that the ducts are securely positioned in the channels and the alignment is maintained along the line.
Cable Pull/Blow Preparation: After the placement and backfill, check that the ducts are still undistorted and ready for the cable blowing/pulling operations.
Final Inspection: Inspect for any displacements, buckling, or misalignment of ducts and spacers before closing the trench or manhole.

Best Practice Tips for Gulf Conditions

Use a sand cushion or fine bedding to support the base spacer and thus prevent the coarse rocks from causing indentations.
Use UV-grade material or a protective cover before final backfill in the installations that are exposed to sunlight.
During installation, protect the spacer arms as they may break due to excessive bending or impact.
Drilling and trenching must be carried out in such a way that the installed spacers are not harmed in any way. Mark their locations for easy access during future maintenance work.

Maintenance, Storage & Lifecycle

Storage Advice

Store in a covered, dry area before installation to avoid UV exposure and deformation.
Keep away from heavy stacking or sharp edges that might warp the base plate.
Retain packaging until ready for lay-down.

On-Site Handling

Handle with care; avoid dropping or dragging the spacer over rough surfaces.
Prior to installation, inspect each unit for cracks, warpage or misalignment.
After duct installation and backfill, minimal maintenance is required as the spacer remains embedded.

Service Life Expectation

In properly installed duct bank systems in Gulf region environments, the spacer’s service life can meet or exceed 25-30 years. Long-term durability is achieved because plastic resists corrosion and remains dimensionally stable underground under proper bedding and backfill.
