SKB

SKB Corporation, founded in 1977 in Orange County, California, is a manufacturer of protective transport cases engineered for industrial, military, and professional audio-visual applications. The company’s product line includes standard protective cases, shock rack-mount cases, heavy-duty transport cases, suitcase-style cases, and long cases, all designed to safeguard sensitive equipment during transit and storage. SKB cases are constructed from high-impact plastic resins, typically rotationally molded or injection molded, providing structural rigidity and resistance to impact, vibration, and environmental exposure. Many models feature IP67 ratings, indicating dust-tight integrity and protection against temporary immersion in water up to 1 meter for 30 minutes. Case closure systems include latch-type closures (e.g., trigger-release latches) and butterfly closures, with folding handles for ergonomic carrying. Interior configurations range from pick-and-pluck foam (customizable by the user) to solid foam or no foam, accommodating a variety of equipment shapes and sizes. Wheeled variants with two wheels and telescoping handles are available for larger cases, reducing manual handling strain. SKB also produces shock rack-mount cases in standard 19-inch rack widths, with depths and heights conforming to EIA-310 rack unit specifications, suitable for mounting electronic equipment such as amplifiers, mixers, and networking gear. The cases are designed to meet military standards for drop, vibration, and temperature extremes, though specific MIL-STD certifications vary by model. 3G Electric supplies a broad selection of SKB cases, including standard transport cases, rack-mount cases, heavy-duty IP67-rated cases, and compact carry-on-sized cases, with interior dimensions ranging from 9 in x 12 in x 4.5 in to 27 in x 27 in x 27 in. The inventory covers models with and without wheels, various foam options, and multiple color choices (black, yellow). 3G Electric supports global procurement by offering these cases for industrial, broadcast, medical, and field-service applications, with technical specifications provided for each SKU to assist engineers and procurement specialists in selecting the appropriate case for their equipment protection requirements.

Common Applications

  • Broadcast and field production — SKB shock rack cases (e.g., 3RS-4U24-25B) for transporting audio mixers and video switchers.
  • Industrial instrumentation — SKB IP67-rated cases (e.g., 3R2727-27B-L) for protecting sensitive measurement devices in wet or dusty environments.
  • Medical equipment transport — SKB standard cases with pick-and-pluck foam (e.g., 3I-2217-10BC) for custom-fitting diagnostic tools.
  • Military and defense logistics — SKB heavy-duty cases with butterfly closures for secure transport of communication gear.
  • Audio-visual rental and staging — SKB long cases (e.g., 3I-4213-12BL) for storing and moving lighting fixtures or cables.
  • Field service and tool kits — SKB compact carry-on cases (e.g., 3I-1209-4B-E) for portable test equipment and hand tools.

Frequently asked questions

Common questions about SKB from 3G Electric.

What IP ratings are available on SKB protective cases?

Several SKB protective cases, such as the 3R2727-27B-L and 3I-1610-10BE, are rated IP67. This means the case is dust-tight (IP6X) and can withstand immersion in water up to 1 meter depth for 30 minutes (IPX7). Not all SKB cases carry an IP rating; standard models without an IP designation are not certified for water or dust ingress protection. Check the specific model's datasheet for IP rating details.

What foam options are available for SKB transport cases?

SKB cases offer several interior foam configurations. Pick-and-pluck foam consists of pre-scored cubes that can be removed to create custom cutouts for equipment. Solid foam provides a blank surface for custom cutting by the user. Some cases, like the 3RS-4U24-25B shock rack case, do not include foam and require separate foam inserts. Cases labeled 'No Foam' are supplied without any interior padding. Verify the product description for foam type before ordering.

Are SKB rack-mount cases compatible with standard 19-inch equipment?

Yes, SKB shock rack cases, such as the 3RS-4U24-25B, are designed to accommodate standard 19-inch rack-mount equipment. The internal width is 19 inches, and the height is measured in rack units (U), with 1U equal to 1.75 inches. The depth varies by model; for example, the 3RS-4U24-25B has a 24-inch depth. Ensure your equipment's depth and height do not exceed the case's internal dimensions.

What is the weight capacity of SKB cases with wheels?

SKB does not publish a universal weight capacity for wheeled cases. The wheels and telescoping handles are designed for occasional rolling over smooth surfaces. For example, the 3I-2217-10BC weighs 20 lb empty and has two wheels; the 3I-4213-12BL weighs 28 lb. The practical load limit depends on the case size, wheel construction, and handle design. For heavy loads, consider cases with reinforced wheels or consult the manufacturer's guidelines.

Can SKB cases be used for air travel as carry-on luggage?

Some SKB cases, such as the 3I-1209-4B-E, are labeled as carry-on size. This case has interior dimensions of 9 in x 12 in x 4.5 in and weighs 3 lb, which generally meets airline carry-on size restrictions. However, airline policies vary, and the case's external dimensions (including handles and latches) may exceed limits. Always verify with your airline before travel. Larger cases without the carry-on designation are intended for checked baggage or cargo.

What closure types are used on SKB cases?

SKB cases use two primary closure types: trigger-release latches and butterfly closures. Trigger-release latches are common on standard transport cases and provide a secure, tool-free seal with a push-button release. Butterfly closures, found on heavy-duty models like the 3R2727-27B-L, use a rotating lever mechanism that applies even pressure across the lid. Both types are designed to withstand repeated use and maintain a tight seal.
