Description
The 165mm Cable Bearer Kit is a key structural support component used inside BT-approved underground duct chambers, specifically within quad box installations. Its purpose is to elevate internal cable arrangements by creating a fixed-height level within the chamber, helping maintain structure and separation across fibre, copper, or other telecom networks.
Manufactured from galvanised steel, the bearer is corrosion-resistant and suitable for long-term use in buried environments. It contributes to organised, compliant installations by supporting the layout of internal components and creating space between cable tiers.
By introducing a consistent internal height, the 165mm bearer allows for improved management of cable slack, routing, and access. This separation is important for minimising interference and enabling clearer visual identification of cables during maintenance. It also supports the long-term functionality of the duct chamber by helping to prevent tangling and damage from overcrowding.
This bearer is sized specifically to align with typical quad box configurations used across BT Openreach and civil infrastructure networks. It is typically installed as part of a multi-level internal layout and may be fitted using approved fixing methods as outlined in installation guides or chamber specifications.
Engineered for practical utility and ease of handling, this bearer can be deployed during initial duct chamber builds or retrofitted as part of an upgrade. It is suitable for various underground projects involving utility networks, local authority infrastructure, or commercial telecom installations.
