600mm Diameter Unsealed Lockable Covers

Larger Access for Septic and Water Tanks

The Nobis 600mm lightweight access cover and frame is designed for larger tanks requiring wider access for maintenance and servicing. It can be cast into concrete tank lids or screwed or bolted onto plastic, steel, or fibreglass tanks, providing a secure and durable solution.

With a 600mm clear opening, this cover supports up to 1.5 tonnes (15kN) while remaining lightweight at less than 10 kg. Its larger size offers easier access for inspections and servicing, making it well-suited for commercial or industrial applications.

Constructed from a fibreglass and special resin composite, the cover is produced under high temperature and pressure, ensuring exceptional strength without unnecessary weight.
