Abstract: A mounting assembly is provided for mounting a sheave roller to a ladder-type cable tray. The cable cables can be laid on the cable tray for routing through a building. The mounting assembly includes first and second housing parts which are moveable relative to each other. The housing parts are attached to respective rungs of the cable tray. A lock prevents the relative movement of the housing parts relative to each other once the mounting assembly is engaged with the cable tray. The sheave roller is rotatably attached to the one housing part. This quickly and easily installs the sheave roller on the cable tray.

Abstract: A mounting assembly is provided for mounting a product, for example a cable feeder, accessory or roller, to a cable tray. The cables can be laid on the cable tray for routing through a building. The mounting assembly includes an elongated rod, first and second arms extending downwardly from the rod and attached to the cable tray, a ratchet mechanism attached to one of the arms, and an attachment member on the other of the arms. The ratchet mechanism includes a ratchet and an extendable and retractable strap. The strap can be extended around the bottom of the cable tray and attached to the attachment member. This quickly and easily installs the product on the cable tray.
