The 1590WTRPCBK is the black textured, watertight "Wide Trapezoid" enclosure in the 1590TRP-STP line. Builders of effects pedals and compact instruments use this shape when they need a broad face for several knobs or footswitches, and the silicone gasket with an IP65 rating adds protection when liquids are a concern.

The box and lid are diecast aluminum alloy with a black textured finish. Aluminum is rugged yet easy to machine, so openings for jacks and controls can be drilled in-house, or the factory can mill, drill or print the case to order. The draft angle on the side walls is 2° or less for straightforward PC board mounting.

Four #6-32 x 1/2" machine screws hold the lid in factory-tapped holes; use 25-30 cN.m [36-43 ozf.in] of torque with the gasket. The 1590WTRPCBK ships as box, lid, 4 cover screws and gasket, weighs 0.54 lbs (0.24 kg), and is RoHS and REACH compliant.
