SKB 3i-5616-9 frequently asked questions

Are SKB iSeries cases waterproof?

Yes. Every iSeries case is IP67 rated and built to MIL-STD 810H. The case is dust tight and submersible up to three feet of water for up to 30 minutes thanks to its gasket-sealed body and ambient pressure equalization valve.

Which SKB iSeries cases are airline carry-on approved?

Several iSeries models meet major airline carry-on size limits, including the 3i-1510-6, 3i-2011-7, and 3i-2114-7. All iSeries cases ship with TSA-acceptable trigger-release latches and the padlock loops accept TSA-compatible locks for checked travel.

What do the numbers in an SKB iSeries model name mean?

The iSeries naming convention is consistent across the line. The first set of digits is the interior length in inches, the next set is the interior width, and the suffix is the case depth. A 3i-2011-7 has roughly a 20" × 11" interior footprint with 7" of depth.

How do SKB iSeries cases compare to Pelican Protector cases?

The iSeries lineup is a direct competitor to Pelican Protector cases. Both are IP67 rated, MIL-STD 810 tested, and pressure equalized. SKB cases typically price below comparable Pelican models, ship with Trigger Latch hardware many users prefer over press-and-pull latches, and carry SKB's unconditional lifetime warranty.

What custom foam and interior options are available for iSeries cases?

We design fully custom interiors for every iSeries case, including pick-n-pluck cubed foam, layered convoluted foam, Nylex-wrapped fitted foam with hook-and-loop dividers, padded photo dividers, and lid organizers with mesh pockets. Empty cases are available when you want to spec the interior with us from scratch.

Do SKB iSeries cases have a warranty?

Yes. SKB-branded hardshell cases carry an unconditional lifetime warranty to the original owner against defects in materials and craftsmanship. If the case body fails in normal use, SKB will repair or replace it for as long as you own it.
