United Rentals has cable rolling tools to help you organize and safeguard your jobsite. This 90-degree radius cable roller is made from welded steel frames, and aluminum alloy sheaves should be used when you need to accommodate a 12" to 18" tray. The rollers are installed up through the bottom of the tray for easy removal after the cable is installed. Individual rollers keep rolling with each cable even after several cables have been installed in the tray with steel, self-lubricating ball bearing rollers for long life and less friction. United Rentals is here as your official tool supplier.
