15 June 2026
Protect liquid assets using WACME’s lockable hinged lids in Australia. Our 455mm hinged lid provides durable, tamper-proof security for industrial tanks.
A 455mm hinged poly tank lid is a direct replacement solution for worn or missing tank covers in Australia. Lockable hinged lids improve access control while keeping the lid securely attached during use. The hinged design reduces the risk of lost lids and supports safer inspection and filling.
Designed for Standard Tank Fit and Secure Access
A 455mm opening matches many poly tanks used in water cartage, agriculture, and civil operations. Lockable hinged lids create a controlled access point, helping reduce unauthorised entry and protecting stored contents.
Durable plastic construction supports long-term use across demanding environments. The fixed hinge keeps the lid attached during operation, while the lockable feature adds an extra layer of security for tanks in active worksites.
Technical Specifications for Lockable Hinged Lids
Correct sizing and material durability influence how well a tank lid performs in day-to-day use. The following specifications reflect practical requirements across Australian tank applications:
- Diameter: 455mm Standard Opening Fit: Matches common poly tank openings, allowing straightforward replacement without resizing or modification.
- Material: UV-Stabilised Polyethylene: Designed to withstand prolonged sun exposure and outdoor conditions without premature degradation.
- Security: Lockable Lid Points: Allows padlock installation to help manage access and reduce the risk of tampering on active sites.
- Design: Integrated Hinged Mechanism: Keeps the lid attached to the tank, helping prevent loss during transport or exposure to strong winds.
- Fitment: Secure Seating Profile: Supports proper alignment on the tank opening to help minimise debris entry and maintain cleaner storage conditions.
Practical Upgrade for Secure and Compliant Tank Access
Lockable hinged lids improve usability by removing the need to fully detach the lid during routine inspections. The hinged structure allows controlled opening, which supports safer handling and more efficient daily operation.
