It clamps 5 to 51 mm tube or flat surfaces with the saddle, giving SkyPanel-style power supplies and similar ballasts a clean, repeatable mounting point on stands, rail, or set tube.\u003c\/p\u003e  \u003ch3\u003eWhy It Matters\u003c\/h3\u003e  \u003cp\u003eA power supply hanging from a cable or improvised plate slows the crew down and looks messy. The KCP-738 makes the PSU mount a known part of the rig, with the Super Convi clamp doing the grip work and the machined plate doing the repeatable rail interface.\u003c\/p\u003e  \u003ch3\u003eKey Features\u003c\/h3\u003e  \u003cul\u003e    \u003cli\u003e Factory-fitted CNC aluminum plate provides a dedicated ARRI PSU Rail Mount Adapter interface\u003c\/li\u003e    \u003cli\u003e5 to 51 mm clamp range works on light stands, speed rail, scaffold, and set tube\u003c\/li\u003e    \u003cli\u003eSuper Convi spring-latch behavior and P.U. pad preserve the familiar clamp handling\u003c\/li\u003e    \u003cli\u003e20 kg Working Load Limit supports properly rigged power supply and ballast mounting\u003c\/li\u003e    \u003cli\u003eStandalone KCP-700-PRM plate is available for crews retrofitting existing KCP-700 clamps\u003c\/li\u003e  \u003c\/ul\u003e  \u003ch3\u003eApplications\u003c\/h3\u003e  \u003cp\u003eBuilt for ARRI ballast and power supply mounting, SkyPanel S60 PSU-style rigs, wheeled light stands, studio rail, scaffold, and any tube or flat surface where the PSU needs to travel with the fixture.\u003c\/p\u003e  \u003ch3\u003e Compatibility\u003c\/h3\u003e  \u003cp\u003e Clamps 5 to 51 mm tube or flat surfaces with the Super Convi saddle.
