Inspection Chamber vs OFC Chamber
Both are RCC precast chambers used underground, but the purpose and lid/fitment requirements differ. Use this guide to avoid ordering the wrong chamber.
1) Purpose
- • Inspection chamber: access point for drainage/utility lines and periodic inspection.
- • OFC chamber: access for optical fiber cable pulling, jointing and maintenance in telecom networks.
2) Size selection
Choose based on clear working space and entry points. OFC chambers often need room for cable loops and joint closures, while inspection chambers are chosen by pipe layout and access needs.
3) Cover / lid
Confirm whether the chamber will be on a footpath, inside a compound, or near traffic. The cover style and seating surface matter for safety and durability.
