Hammond 1590BBSOR Orange Diecast Aluminum Enclosure - Rugged

In this review the Hammond 1590BBSOR is evaluated as a compact, heavy-duty enclosure for electronics hobbyists and small professional builds. The biggest reason to buy is its combination of rugged diecast aluminum construction and practical protective design, which offers improved EMI/RFI shielding and a lap joint that helps keep out dust and splashes. It ships with countersunk screws and pre-tapped holes so the lid installs cleanly, making it a straightforward option for anyone needing a durable, paint-finished case in a distinctive orange.

Key Features

• Diecast aluminum alloy: Provides a tough yet machinable shell that stands up to workshop use while allowing drilling and modification.
• Lap joint construction: Helps protect internal electronics from dust and light splashes and contributes to the enclosure's ingress protection.
• Improved EMI/RFI shielding: The metal body reduces interference for sensitive circuits and provides a solid ground path for internals.
• Pre-tapped holes and countersunk screws included: The lid fastens securely out of the box, making assembly quick and neat for prototypes or finished projects.
• Orange RAL 2009 finish: A visible, factory-painted color option that suits projects requiring high visibility or a finished appearance.
• IP rating options: Designed to meet IP54 as standard and can reach IP66 if a gasket is purchased for tighter sealing.

Who It's For

The Hammond 1590BBSOR is ideal for electronics hobbyists, small-scale instrument builders, and technicians who need a compact, protective metal case that is easy to modify. Its sturdy diecast body and included fasteners make it a good choice for enclosures that require solid construction without extensive casework.

It is less well suited to projects that require complete waterproofing without modification or finishes that resist heavy abrasion to the paint. If maximum size or a different color is required, other sizes in the same family or a custom-painted option from the factory may be a better fit.

Pros & Cons

Pros

• High-quality, heavy-duty diecast aluminum provides durable protection and good EMI/RFI shielding.
• Factory-painted orange finish looks professional and stands out for visible installations.
• Includes countersunk screws and pre-tapped holes for easy, neat assembly.
• Lap joint design improves dust and splash protection and overall durability.

Cons

• Paint scratch resistance can be a concern under heavy handling or abrasive use, so careful finishing or touch-up may be needed.
• Standard IP54 rating is protective but not fully watertight unless a gasket is added to reach IP66.
