MSA XTIRPA confined space entry systems allow for vertical or horizontal entry into common confined space applications such as tanks, vessels, transformers, sewers and manholes. Systems are lightweight, portable, easy to set up and provide fall protection when a portable base is needed, allowing for users to save time. Manhole Guard with Integrated Mast barricades provide the necessary strength needed for fall protection, entry and retrieval applications. Adapter Base Systems are fixed anchorage connectors used for vertical entry into confined spaces.
