Call for Availability150x100mm precast chamber unit with a round door, avoiding a brick-built manhole at a twin branch junction below ground.
- Configuration - Round door chamber sized for a twin branch junction.

Installing a full brick or concrete manhole is not always proportionate for a smaller buried junction. The Halifax HD6480 packages a twin branch junction and a round access door into one 150x100mm precast unit that drops straight into the run.
Why a chamber unit
Maintenance access at a junction follows the same general principle as elsewhere in BS EN 12056-2: somewhere to rod and inspect the pipework without digging it up. A precast chamber gets there without the labour of building a manhole from scratch, and this round door version is sized for a twin branch configuration.
Build
- Casting - Produced in grey cast iron under BS EN 877, with an epoxy finish averaging no less than 150 microns.
