The standard cabinet (left) is 30" wide x 24" deep x 84" high. The large cabinet (right) is 60" wide x 24" deep x 84" high. Each contains a white chemically-resistant fiberglass liner with smooth, rounded corners to prevent trace evidence from being trapped in the corners and being carried over from case to case, and for easy cleaning with bleach solutions. The outside construction is polyurethane-coated aluminum frame and head assembly with an aluminum base support. There is a clear Lexan door, a stainless steel coat rack, and a built-in drain.

Each style cabinet is corrosion proof, has a locking door, and an alarm to detect low air flow, and is ductless in design. There are particulate pre-filters in the lower door grill and the main filter inlet, a HEPA filter (two in the large unit), chemisorptive carbon filter (two in the large unit) and an after filter for maximum protection. The visible safety alarms indicate whether the system is functioning properly, whether it is necessary to replace the door pre-filter, main HEPA filter or the after filter. The units have washdown capabilities with optional plumbing and hoses. The shelves shown in the photographs and clothing separators are available for purchase separately. Another option is the Formalin sterilizer for use when the HEPA filter is exhausted.
