The Middle Atlantic UCP Custom Panel System is a highly modular 1U rack-panel platform designed to host a wide range of connector modules—like input jacks, keystone inserts, XLR, BNC, D-sub, Socapex, banana, twist-lock, Amp, Elco, Whirlwind, Canon, and circular flange plates. Built on an anodized aluminum frame or chassis, it provides a professional, flush-finished look. Panels may be standard or hinged for rear-access, enabling hot-swappable connectivity without removing the rack panel.
