Field-ready expandable design

With its accordion-style expandable frame, this barrier can be deployed in seconds — no tools or anchoring required. It effectively surrounds open manholes, inspection chambers, service pits, or underground access points while remaining stable once positioned.

When folded, it becomes extremely compact, making it easy to transport, store, and handle — even in small service vehicles.

Strength and visibility for urban environments
