The shell of each Hardigg double lid rackmount case is rotationally molded, so it's rugged and recyclable, with corners that are 15% - 20% thicker to absorb shocks better and molded-in color that can't wear off.  the tongue-in-groove gasketed parting line seals tight, even after impact, because it's molded right in. 

Each Hardigg Case is designed with interlocking ribs for stable stacking.  Patented stainless steel inserts are molded-in to ensure riveted hardware connections are strong, and easily replaced, if necessary.  The patented anti-shear interlocks protect closure hardware from damaging shear forces during drops.  All hardware is fully recessed, including optional coupling catches for stacking security.

Case Options
Hardigg offers a broad range of standard options.

Airtight case system. This includes a PRV (pressure relief valve) and gasketing hardware to safely maintain correct pressure differential. Manual release button is recessed below cover rim. Test pressure range is +/- 0.25 PSID (18 mb).

Bezel plate. Blank bezel plates in 16 gauge aluminum. Flanged for strength. Brushed black anodized finish. Available in 1U, 2U, 3U, and 4U heights.

Caster sets. Hardigg-engineered caster mounting system enhances the bottom panel strength of rack cases, while providing the same button release convenience of the FastClipÔ mounting plate system found on Hardigg’s single-lid cases. These swivel style casters are Colson or equivalent brand, available in removable or fixed 3.5" or 5" wheel diameters. The caster set includes four casters, two machined aircraft aluminum extrusions, and mounting hardware installed on the case bottom.

Caster store-in-lid system. Removable casters are securely stored in lid using Hardigg FastClipÔ mounting plate system. For 5" (127 mm) lids only.

Foam cushioning. To transport non-rackmountable equipment, we custom-design protective foam linings and inserts. Hardigg cushioning systems are available in polyethylene (firmer) and polyurethane (softer) foams. Antistatic versions are also available. This option is a major element in equipping double-lid cases used to transport workstations.

Frame option rack extension – 1/8" wider. Used when extra clearance is necessary, usually to accommodate slides. Requires slotted mounting holes in attaching bezel of equipment to be mounted.

Handles – extra. These 90° stop metal handles are rated to sustain 150 lbs. of lift. Available in zinc-plate yellow-chromate or stainless steel.

Humidity indicator. Indicates 20%, 30%, and 40% relative humidity ranges. Three-part face changes color when inside humidity exceeds the indicated level. As humidity decreases, the indicator resets for future use. Recommended for airtight cases only.

ID plates. I.A.W. MIL-P-15024, Type H, Style IV, Size 10.4" x 4" x .020" (102 x 102 x 0.5 mm) thick aluminum, fastener attached to your case. Text font is News Gothic Bold.

Rack frame/shock-mount guidelines for extra-heavy loads. For rackmount cases with more than 170 lb. (77 Kg) of packaged equipment, sixteen elastomeric shock mounts are used instead of the standard eight. Vertical metal wall stiffeners are added to the case body to retain dimensional control of the two openings and ensure that the covers can easily go back on the case body and latch properly. Four delta lifting/tie-down rings are also installed to provide mechanical lift accessibility.

Rack slides. These compact solid-bearing steel slides may be used to mount equipment directly into rack, or to mount drawers or shelves. Sold in pairs. Available in standard duty, 85 pound capacity.

Shelves – fixed and sliding. Shelves can be removed and customized to accommodate non-rackmountable equipment.
