Custom ATA Cases

There's a difference between buying a case from a manufacturer and buying a case from a supplier who orders cases from a manufacturer. Most buyers find out about that difference the hard way — when a foam pattern can't be reproduced, when a reorder doesn't match the original, when a question about hardware specs takes three weeks to route through a supply chain. The cases that hold up across years of program reorders, the cases that ship to spec from the first prototype to the thousandth unit, are the cases that come from a manufacturer who actually makes them.

Platt Cases manufactures custom ATA cases on the Guardsman™ platform — a patented continuous industrial frame construction built from heavy-duty HMW polyethylene. Guardsman cases are tested to ATA 300, Category 1 specifications for vibration, water resistance, tumbling, and drop, and they outperform plywood ATA cases on weight, durability, crack resistance, and chemical resistance.

Custom Guardsman programs start with a proven platform and finish with the customization that fits the equipment, the program, and the brand — custom foam interiors, hardware configuration, exterior branding, and color.

When a Custom Guardsman ATA Case Is the Right Platform

ATA cases are the right choice when a case has to survive repeated transport — trade show shipments, field deployments, freight handling, and air travel. The Guardsman platform is engineered specifically for that profile.

Guardsman ATA cases are used across industrial instrumentation, medical device deployment, electronic equipment transport, computer and AV programs, and field service kits. The platform supports equipment loads, layered foam builds, and panel-mounted hardware that other ATA constructions cannot consistently carry. To understand how this fits into our baseline framework, check our master updated Custom Products Hub or view our active Custom Case Manufacturing capabilities guidelines.

Guardsman™ Construction

The Guardsman platform is built around three structural elements: HMW polyethylene, the continuous industrial frame, and the hardware. Every element is engineered for repeatable transport, not single-trip protection.

• HMW Polyethylene Shell: High molecular weight (HMW) polyethylene thermoplastic sheets are bent to size and assembled into the case body. The material delivers high-impact strength, crack resistance under repeated drops, chemical resistance for industrial environments, and lower weight per cubic foot than plywood ATA construction.
• Patented Continuous Industrial Frame: Platt's patented Guardsman frame runs the full edge of every panel — locking the shell together, distributing impact loads, and accepting the hardware that ties the lid to the body. The continuous frame is the structural difference between Guardsman and conventional aluminum-extrusion ATA cases; impact energy is dispersed across the full frame rather than concentrated at corner extrusions.
• Heavy-duty aluminum rim and gasket: Engineered for repeatable opening and closing under field conditions.
• Full-length piano hinge: Distributes lid load across the entire back edge instead of two or three hinge points.
• Recessed spring-loaded handle: Flush with the case body when not in use; rated for the case's loaded weight.
• Recessed latches and hardware: Protected from forklift forks, freight edges, and stacking damage.
• Built-in TSA-accepted combination lock: Standard on stock Guardsman models; available on custom programs.

How a Custom Guardsman Program Gets Built

Standard Guardsman construction is the starting point. The custom program is what fits the case to the equipment list, the program volume, and the brand.

Custom Foam Interiors

Custom Guardsman cases use the same foam engineering approach as the rest of Platt's custom programs. The foam insert is where most of the protection work happens — the plastic provides the outer structure, the foam keeps the equipment from moving under shock and vibration.

• Polyethylene (PE) foam: Firm closed-cell foam — resists compression set, holds pocket geometry over time; the standard for industrial and field service programs.
• Polyurethane (PU) foam: Softer open-cell foam — higher cushioning for shock-sensitive equipment; used in precision instrument and electronics programs.
• Low-abrasion foam: Soft-surface foam for programs involving polished, painted, or finish-sensitive equipment.
• Anti-static (ESD) foam: Static-dissipative foam for programs involving PCBs, sensors, and assemblies with exposed conductors.
• Layered foam builds: Combinations engineered to the equipment profile.

Stock Guardsman cases with an "L" suffix ship lined with high-density foam. Cases with an "F" suffix ship lined and filled with solid foam layers — the buyer can configure the foam in the field, or Platt can customize the foam to a precise equipment fit. Custom foam programs may carry minimum order requirements. For more on foam material selection and the foam design process, see Custom Foam Inserts at plattcases.com/custom-foam/.

Hardware and Mobility Options

To support advanced field mobility deployment metrics, we engineer multiple expansion updates:

• Built-in wheels and telescoping handle — standard on Guardsman "HW" models, available on custom programs.
• Fixed or removable casters — for cases too large for telescoping handle programs.
• Padlockable latches and key locks — for programs requiring chain-of-custody documentation or non-TSA lock formats.
• Stacking studs — for programs that stage multiple cases together in transit or storage.

Exterior Customization and Branding

Guardsman cases ship standard in black. Safety yellow, gray, orange, and blue are also stock colors. Other custom colors are available with minimum order requirements. Branding is applied through custom aluminum nameplates mounted to the case exterior — durable, refinishable, and survivable through the program lifecycle. Logo, model identification, asset tagging, and customer-specific marking are all standard options.

Stock Guardsman™ Sizes

Programs requiring a non-standard footprint are quoted as fully custom Guardsman cases — all program sizes are available, in quantities as few as one case.

*1013 is sized for airline carry-on. All stock models include built-in TSA-accepted combination lock. You can review full design parameters across alternative shapes on our updated Custom Molded Cases overview, or review standard engineering schematics via the root source Guardsman Reference Guide.

How a Custom Guardsman Program Works at Platt Cases

We move your custom enterprise requirements safely from basic measurements to scaled regional drop shipments using six distinct stages:

Program timelines: Custom Guardsman programs typically run 3–6 weeks from approved specification to first shipment, depending on foam complexity, custom color requirements, and program volume. Fully custom Guardsman sizes outside the stock footprint may extend timelines for first-article production.

Typical Custom Guardsman Programs

Industrial Instrumentation

Test instruments, calibration equipment, portable analyzers, and field measurement tools. Custom Guardsman cases protect the instrument, organize the accessories, and survive repeated transport between facilities. Foam is engineered for shock isolation and pocket retention under cyclic vibration.

Medical Devices and Field Clinical Equipment

Demo equipment for clinical sales programs, portable diagnostic devices, and field service kits. Custom Guardsman cases support program-specific equipment layouts, branded nameplates, and the durability profile required for repeated travel between hospital sites and conference deployments.

Electronics and Computer Equipment

Server transport, AV control gear, industrial controllers, and field-deployable computer kits. The Guardsman platform supports heavier equipment loads and panel-mounted hardware. Anti-static (ESD) foam options are available for programs handling exposed conductors and PCBs. Learn more about matching custom shells to precise technical cutouts on our Custom Pelican Cases center.

Military and Defense Programs

Field equipment, deployable kits, and program-specific transport cases. Guardsman construction supports the ATA-300 transport profile, custom color options for service branch standards, and the hardware configurations required for chain-of-custody and field handling.

AV and Trade Show Programs

Touring AV equipment, demo programs, and trade show booth gear. The Guardsman platform handles the trade show profile — constant transport, frequent third-party handling, and the appearance requirement of looking professional after thirty trips.
