Greenlee cable tray accessories: 666QA, CTR100 and CTR200
By Anthony Capkun
December 10, 2014 – Greenlee offers new accessories for non-basket-style cable trays: the 666QA quick-adjust sheave roller, and the CTR100 and CTR200 cable rollers.
The cast-aluminum, adjustable 660QA roller is designed to fit on tray rung spaces up to 20-in. apart, and can handle forces of up to 100 lb. A set screw handle locks and unlocks an adjustable sliding leg, eliminating the need to access the top and bottom of the tray to securely attach the sheave.
The CTR100 and CTR200 rollers are specifically designed to assist at heavy load points around 90° bends, offsets, and vertical rises and drops, while not taking up space in the tray. The four conveyer rollers securely trap the cable within the guide, not damaging the cable jacket and allowing the cable to smoothly glide through. The roller is designed with a retained spring pull-pin release, allowing users to easily free the cable into the tray. Steel construction allows the CTR100 and CTR200 to withstand cable pulling loads up to 100 lb and 200 lb, respectively.
