Permanent Cover Plates
Heavy-duty shaft closures for permanent inflow and overflow protection. Secure, durable, and easily removable for inspection.
HEAVY-DUTY SHAFT CLOSURES
Our permanent cover plates offer a high-performance solution for sealing circular channel inflows, overflows, and installation shafts. Suitable for crack-free circular channel inflow, overflow or installation shafts — for horizontal or vertical installation.
The closure element features a massive one-piece steel plate and an adapted counter ring. A special round seal is inserted between the base plate and the counter ring, closing the shaft safely and tightly.
The system is easily removed for inspection work. The seal is to be renewed upon re-installation.
Round One-Piece Form
Massive one-piece steel plate design ensures a robust and durable closure for circular shafts.
Secure Bolting
Counter ring mechanism presses the seal tightly against the shaft perimeter for absolute containment.
Universal Installation
