The 1590AOR is a compact 1590A-size rectangular diecast aluminum stomp box enclosure, finished in a glossy orange (RAL 2009) powder coat. It is made for stomp box builders and hobbyists who want a bold, ready-coloured enclosure, and at a nominal 93 x 39 x 31 mm (3.66 x 1.54 x 1.22 in) it suits small single-function pedals and compact electronic projects.

The enclosure is rugged diecast aluminum alloy, tough yet easy to machine. It is factory powder coated to save builders time and money, with a smooth glossy polyester powder coat that gives a lasting finish even after machining. The smooth surface allows easy adhesion of labels or silk screens, and the orange colour is matched to RAL 2009.

Lap joint construction protects against access of dust and splashing water, and the box is designed to meet IP54. Adding the optional 1590AGASKET kit together with water-tight screws is required to reach IP65. The side wall draft angle of 2 degrees or less makes PC board mounting easier.

Replacement hardware includes nickel plated #6-32 x 1/2 in screws (1590MS100, package of 100), black screws (1590MS50BK, package of 50), and tamper-resistant nickel plated or black screws (1590MS50T or 1590MS50TBK, packages of 50). The 1590AOR ships at 0.32 lbs (0.15 kg) and is RoHS and REACH compliant.
