The 1590WBFLBK is the black textured, water-tight 1590B-size diecast aluminum enclosure with a flanged lid for wall mounting. It is a compact, painted metal housing for product engineers, panel builders and integrators that mounts through the lid and is designed to meet IP65.

Box and lid are diecast aluminum alloy, a material that is tough yet easy to machine. The black version is coated with tough polyester powder paint that holds a lasting finish, even after machining; black screws are included to enhance appearance. Lap joint construction where lid and box meet protects against dust and splashing water, and the included silicone gasket is supplied loose inside the enclosure.
