A cable cleat is a cable restraint device (sometimes called a cable block, cable bracket or cable clamp) that is designed and tested to provide securing and retention of cables. A cable cleat is typically fixed to a mounting surface (e.g. ladder-type cable tray rung) and fastened around one or more cables. According to IEC 61914 and UL 2239, neither conduit clamps, P-clamps or cable ties are considered to be cable cleats. Cable cleats may be applied to single conductor or multi-conductor cables.
