ACO can offer 2-part solid top access covers to meet your requirements
Due to the number of removable components including beams and individual covers, multipart access covers by their very design cannot be made water tight. This is why AS 3996-2006: Access covers and grates excludes large access cover systems from its scope. AS 3996-2006 requires compliance in a number of areas including gas and water tightness. ACO multipart covers are suitable for applications requiring general weather resistance on well drained enclosures. A reasonable degree of weather resistance can be achieved by sealing edges of covers, frame interfaces and lifting holes each time the cover is removed for servicing.
For applications requiring frequent access, ACO’s Servokat Assist lift covers are recommended.
