Cable Pulling/ Tensioning Rollers

Cable pulling equipment in the electric, telecommunications, and related industries use rollers to support the line being installed and for directional changes to protect the line from damage. This includes support blocks, snatch blocks, corning arrays/quadrants, and boom point roller-type sheaves on a variety of stringing equipment extensions.  These rollers were initially made of steel or aluminum, but corrosion damaged lines and safety concerns due to part weight led to changes. Rubber and urethane rollers have been used, but they have limitations caused by weathering, chemical attack, and wear.  

Using nylon in place of steel, rubber, or urethane allows for improved performance and operational efficiency as nylon rollers are lightweight and will not cause damage your cable due to corrosion and wear.
