A manhole entry barrier is an adjustable aluminium frame that closes an open manhole during maintenance, inspection and installation work. It physically stops unauthorised or accidental entry, carries the warning signage required by OSHA 29 CFR 1910.146 for permit-required confined spaces, and keeps weather, debris and pests out. One barrier adjusts across a range of opening sizes thanks to M16 feet on swivel bases; seven size ranges cover 25 to 200 cm. Optional locks make it part of a Lockout-Tagout procedure.
