Which part of a Deployable Hard Case should a command post fix first?

Answer: The bench. Once its size is set, outer dimensions, hinge type and stack height follow.

Can a cut case still keep water out?

Answer: Yes, with a gasketed gland. An M32 gland torques to about 4 N·m, and the wall within 3 mm of the bore must be free of witness lines.

Why not use a cooler box for medical work?

Answer: A cooler controls temperature only. Medical work also needs a liner that lifts out whole, R15 corners and layered instruments.

Can a repair case and a test case be merged?

Answer: For small quantities, but tray travel and bore position collide, and the merged body grows to 420 mm high.

How is stack height decided?

Answer: From lid compression on the bottom case plus the transport height limit. Three high suits a command post box.

Deployable Hard Case Applications: Scenarios and Configurations

Quick answer: A Deployable Hard Case is judged by how fast it turns into a working surface. Command posts want a bench and power, relay sites want routing and shielding, medical teams want temperature control. Scenario first, then liner, cutouts and stacking.

1. Where a Deployable Hard Case Works: Five Roles

Closed in transit, a Deployable Hard Case stacks better when small and light; open on site, the same body must become a bench, a rack or a tray of drawers. Flattening the lid for working area costs compression strength; thinning the wall costs stiffness at every bore.

Four constraints hold in every role: first tool out within 90 seconds, an opened lid taking three times its own weight in side push, cutouts moulded rather than drilled, lifting points shared with the stacking marks.

Role	Cycle	Job and constraint
Field command post	2 to 6 hours	Bench and cable hub, load
Relay site	30 minutes to 2 hours	Rack and patch box, shielding
Medical forward	15 minutes to 1 hour	Drug bench, temperature
Test and repair	20 minutes to 3 hours	Tool trays, compartments
Field laboratory	4 hours to 2 days	Instrument base, load

2. Field Command Post: Surface First, Power Second

A command post Deployable Hard Case is a bench first: a detachable lid drops back over the rim, flush with the opening, giving an 800 × 600 mm work area with the document pockets facing down.

Deployable Hard Case: an orange case on wet steel grating, two black straps pulling outward, two latches and a centre handle, grey ship structure behind

Power comes second: two 32 mm bores with M32 glands, wiring in wall channels, mains and 24 V on separate breakers, the panel recessed 15 mm, the M6 earth stud on a frame insert. Stacking is three high, under 42 kg, on 8 mm cones.

3. Relay and Medical Forward: Routing and Temperature

At a relay site the cutout matters most. RF cable needs a bend radius of five times its diameter, and the bore sits 40 mm from the inner wall. A conductive gasket holds 0.5 mm; without it shielding drops from 60 dB to 30 dB. Louvres face down behind a filter, and a 2 mm plate set 12 mm off the wall lets heat out at the base.

Medical work starts at 2 to 8 °C for six hours: a 30 mm polyurethane liner, 12 mm phase-change slots near the wall, a liner that lifts out whole, R15 corners.

4. Test, Repair and Field Lab: Cutouts and Load

A repair case behaves like a drawer cabinet: three trays at 15 kg each on side rails, one 20 mm bore in the upper third of the wall, clear of the tray travel.

Deployable Hard Case: an orange case closed on a dark backdrop, four lid ribs, one latch and clamp each side, round valve by the handle

A field lab uses the body as a base: a 60 kg bench, 10 mm pads, four feet at ±10 mm, four DN50 ports, two in and two out. Both sit under 350 mm high, keeping the centre of gravity low.

5. The Configuration Matrix

Read the matrix in one order: liner, cutouts, stacking. Reverse it and the bores are redone.

Scenario	Liner	Cutouts	Stack, rating
Command post	25 mm EVA, lid pockets	2 × M32, M16 earth	3 high, IP65
Relay	30 mm EVA on alloy plate	2 × M25 with gaskets	2 high, IP66
Medical forward	30 mm PU, phase-change slots	1 × M20 probe port	2 high, IP65
Test and repair	15 mm EVA, three trays	1 × M20 test port	3 high, IP54
Field laboratory	20 mm EVA, instrument pads	4 × DN50, M32 inlet	1 high, IP54

Borrowing across roles is the usual mistake. A command post case on repair duty has its bore blanked by the top tray; a medical case built like a repair box has corners too tight to free the liner.

Conclusion

What separates one Deployable Hard Case from another comes down to four settings: liner form, cutout position, stack height and rating. Settle them at drawing stage and no bore is blocked, no liner trapped, no vent shut, and that is what a Deployable Hard Case is for.
