NSN 6650-01-685-1821 Protective Cases

National Stock Number 6650-01-685-1821 is associated with the black SKB iSeries 3i-3019-12BC waterproof optical instrument case with a cubed foam interior.

The 3i-3019-12BC is manufactured from ultra-high-strength injection molded polypropylene copolymer resin. Its gasket-sealed, IP67-rated construction is waterproof, airtight, dust-tight, and submersible, helping protect optical instruments, test equipment, electronics, and other sensitive contents during transportation, storage, and field operations.

Standard features include molded-in hinges, a Trigger Latch® system, stainless steel-reinforced padlock holes, snap-down rubber over-molded cushion-grip handles, secure stacking, and an automatic ambient pressure equalization valve.

An industrial-strength retractable pull handle and four wide-set in-line skate-style wheels make the case easier to move when loaded. The rugged exterior is resistant to UV exposure, solvents, corrosion, fungus, and impact damage.

The supplied interior includes multiple layers of pre-scored cubed foam in the case body and convoluted foam in the lid. Individual foam sections can be removed to create compartments around optical instruments, imaging equipment, test devices, electronics, communications systems, tools, field equipment, and other valuable contents.

Cases2Go can supply the original SKB 3i-3019-12BC cubed foam configuration or provide a precision-engineered custom foam interior when the equipment requires more controlled cushioning, support, organization, or long-term protection.

Confirm the required NSN, manufacturer part number, interior configuration, color, dimensions, and procurement specifications before ordering.
