H-Series Bracing System
H Series Double Acting Manhole Frames
Designed for larger excavations, our H Frame Series Double Acting Manhole Frame is a tried and tested bracing system with interchangeable brace leg sizes.
The H series frame is an extremely robust and adaptable system that can be used alongside trench sheets to create manholes or larger tank excavations at depth.
When digging excavations, always remember to take into account the measurements for the Trench Sheet pan depth as well as the Manhole Frame section.
