25x Purple Anti-Rattle Ring With 66 cm or 68 cm Outer Diameter, 25 Pcs.

Purple anti-rattle ring with 66 cm or 68 cm  outer diameter, stops noise pollution caused by rattling manhole covers. The price in our shop refers to a pack of 25.

Optimal insert rings against rattling manhole covers, made of high-quality, low-wear plastic. Due to their easy application and dimensional stability, the new, cassette-shaped support ribs with tapered upstands are extremely adaptable, ensuring a stable and secure position of the cover. The bevelled outer support edge ensures the centred positioning of the cover and prevents lateral shifting. This gives the manhole cover continuous support, with no room for unwanted movement. This minimises annoying rattling noises and helps to protect the manhole frame and manhole cover, extending their service life.
