PVC Manhole Katori: Complete Guide
The durability and safety of underground drainage systems, sewer networks, utility chambers, telecom manholes, and stormwater infrastructure depend not only on the manhole cover but also on the quality of the supporting accessories used during installation.
One of the most essential yet often overlooked components is the PVC Manhole Katori. It plays a vital role in securely holding and protecting the lifting arrangement of manhole covers while ensuring smooth opening and closing during maintenance operations.
A PVC Manhole Katori is a specially designed high-strength PVC insert installed inside concrete manhole covers to accommodate lifting hooks, lifting keys, eye bolts, or handling accessories. It prevents concrete damage, improves durability, protects embedded lifting points, and simplifies future maintenance.
Also known as PVC Katori, Manhole Cover Katori, PVC Cup for Manhole Cover, Manhole Lifting Cup, Concrete Manhole Katori, PVC Insert for Manhole Cover, PVC Manhole Cup, Drain Cover Katori, Inspection Chamber Katori, or PVC Embedded Cup, it is widely used in municipal infrastructure, drainage systems, telecom chambers, utility networks, industrial plants, airports, highways, and smart city projects.
TRP Machines & Tools, Mumbai, Maharashtra, India, manufactures premium-quality PVC Manhole Katori designed for strength, durability, dimensional accuracy, and long service life.

What is a PVC Manhole Katori?
A PVC Manhole Katori is a precision-moulded PVC component embedded into precast or cast-in-situ concrete manhole covers. It creates a smooth, durable, and protected cavity where lifting keys or lifting hooks can be inserted for opening the manhole cover safely.
Unlike directly casting lifting holes in concrete, PVC Katori protects the concrete from damage caused by repeated opening and closing of the cover.
Why is a PVC Manhole Katori Required?
Repeated maintenance operations can damage concrete lifting holes, making manhole covers difficult and unsafe to handle.
PVC Manhole Katori helps by:
How Does a PVC Manhole Katori Work?
Step 1 – Installation During Casting
The PVC Katori is positioned in the mould before concrete is poured into the manhole cover.
Step 2 – Concrete Casting
Concrete surrounds the PVC insert, permanently embedding it within the manhole cover.
Step 3 – Curing
After curing, the PVC Katori forms a smooth and durable lifting recess.
Step 4 – Maintenance Operation
A lifting key, lifting hook, or eye bolt is inserted into the PVC Katori to safely lift the manhole cover.
Step 5 – Repeated Use
The PVC insert protects the surrounding concrete during repeated maintenance operations.
Why is Proper Lifting Arrangement Important?
Manhole covers require regular access for inspection and maintenance.
A proper lifting arrangement helps:
