The InfraLOCK Release prevents manhole lids from dislodging during explosive events by safely releasing pressure while securing underground infrastructure. The drop-in replacement manhole cover for utilities, sewer systems and underground utility systems incorporates ABLOY high security locks; it is designed to release built-up pressure without dislodging from the frame and includes an ultra-strong locking system to secure access. Offering outstanding benefits of security and added safety, it can be used for many different applications, ranging from water mains and sewer systems to other underground utilities in critical infrastructure sectors.
