Greenlee 50110403 Conduit Piston, Flexible Foam Body, Steel Center Rod

Greenlee 50110403 Conduit Piston, Flexible Foam Body, Steel Center Rod

The Greenlee 50110403 Conduit Piston is engineered to work with a blower or vacuum power fishing system to pioneer the pull line through a conduit run, giving electricians and cable installers a fast, reliable way to establish a path before pulling wire or cable. Its flexible foam body creates an air-tight seal inside the conduit so blower or vacuum pressure can effectively drive the piston through the run, while a strong steel center rod with loops on both ends provides a secure attachment point for the fish line. Conduit pistons in this line are available for all types and sizes of conduit from 1/2 IN through 6 IN, and each piston features a color-coded end disk with embossed size markings for fast, easy selection on the job site. This design helps reduce guesswork and setup time when matching the correct piston to the conduit being run, keeping installation crews moving efficiently on demanding commercial and industrial jobs.
