Composite Access Cover


Access Covers

With a large range of access covers to compliment our access chamber systems, individual needs can be met with a bespoke cable protection combination.

Cubis AX-S™ Composite covers offer a lightweight solution with no reduction in loading performance. A wide range of sizes can be manufactured utilising multi-cover frames, with options for bespoke customer badging.

AX-S™ Composite covers are designed for use with STAKKAbox™ Modula chambers

How do access covers work? Cubis access covers are used in combination with access chamber systems to protect the infrastructure networks below. A suitable frame with additional cross pieces are fitted to the chamber top. The AX-S™ Composite covers are then placed carefully into the frame, with grommets added in the lifting points and the cover secured using supplied screws.

Features & Benefits

Variable Sizes

Composite Covers can be manufactured in a variety of sizes, bespoke to unique requirements. Cross-beams and cross-pieces can be used to build multi cover units.

Bespoke Identity

Covers can be badged with bespoke information to enable easy identification by operatives.

Access Cover For Safety

When it comes to keeping infrastructures safe, composite access covers are a perfect solution. Covers are subtle and disguised as to deter attention from thieves. This eliminated the cost of additional safety measures such as the guarding of open chambers. AX-S™ Composite access covers are fitted with bolt-down locking which can be specified to the end user’s requirements – preventing access to the infrastructure network below.

Long lifespan

Cubis access covers have log lifespans, reducing costs for replacements by the end user.


An anti-slip design results in a more efficient system, with this access cover featuring a non-slip tread pattern, exceeding a Slip Resistance Value of 80. Covers can also be easily removed due to its lightweight nature of under 30 kg.

Accessible Access Cover

Permeable to Radio Waves, the composite access cover allows for telemetry readings to take place easily, without removing the cover.

Composite Access Covers How It Works

How The Composite Cover Works

Covers are fitted into a suitable frame from the Cubis range of access chambers. Network infrastructures are then protected with a tamper-proof system. Being under 30kg, the composite cover’s lightweight properties make it easy to install and remove when needed.

AX-S™ frames are manufactured to meet the exact specification of each project. The range has been developed to offer installers tailored solutions to problems experienced on site.

AX-S™ Composite covers meet the vertical load classes of A15, B125 and C250 set by EN124.
