Properties of Solid Top Manhole Covers
- Closed Keyholes – All lifting keyholes are closed at the bottom. This prevents foul smell from escaping and stops dust or foreign particles from entering the chamber.
- Double Seal Design – Every manhole cover has a double seal for extra safety and protection.
- Reinforced Keyhole Inserts – All lifting keyholes are fitted with high-strength plastic alloy or stainless steel sockets. This ensures the area around the keyholes does not get damaged even after repeated lifting operations.
