Jameson 90° Corner Block Cable Roller | Single, Dual Row & Quad
Jameson 90° Corner Block Cable Roller | Single, Dual Row & Quad — Product Overview
Jameson 90° Corner Block Cable Rollers guide fiber optic and coax cable smoothly around pole corners during aerial installation. Available in Single, Dual Row, and Quad configurations, these blocks help distribute pulling pressure while maintaining cable control through direction changes. Steel side plates add strength, and the adjustable keeper arm helps keep cable properly seated during the pull.
This family includes models with standard nylon rollers as well as aluminum roller versions for reduced friction. The 90° corner block design features a 17" bend radius and is sized for cable up to 1" maximum diameter, making these ideal for aerial fiber and coax placement.
