The NCM Pigtail Eyebolt is an end-anchored eyebolt that is full column grouted post-installation providing reliable anchoring for the suspension of services such as air, water, ventilation piping, electricity and communications in underground mining operations.
A specially designed seal ensures easy grouting of the installed Pigtail Eyebolt with minimal spillage of grout during pumping. In applications where corrosion is a concern the Pigtail Eyebolts can be Zinc Diffused to increase the corrosive life of the bolt.
