What makes the Model 4BX different from a standard 4-body mortuary cooler?

The 4BX Extra-Wide features wider interior tray dimensions, reinforced tray slides for higher weight capacity, a wider door opening with matching thermal seal, and an upsized compressor matched to the expanded interior volume — all engineered for bariatric decedent storage.

What weight capacity do the 4BX trays support?

Contact American Mortuary Coolers at 1-888-792-9315 or service@mymortuarycooler.com for specific tray weight ratings. The 4BX is engineered for bariatric decedent storage well beyond standard-width tray specifications.

Is the 4BX mortuary cooler OSHA compliant for bariatric cases?

The 4BX is designed to reduce the ergonomic hazards associated with bariatric decedent handling, supporting OSHA general duty clause compliance. For specific OSHA guidance, review the American Mortuary Coolers compliance roadmap page.

Does the Model 4BX maintain CDC storage temperatures?

Yes. The 4BX maintains CDC-mandated 34°F–38°F storage temperatures with an upsized commercial-grade compressor rated for ambient environments up to 95°F.

4-Body Bariatric Mortuary Cooler — Model 4BX Extra-Wide for Oversized Decedent Storage

May 31, 2026 3 min read

The Model 4BX Extra-Wide is American Mortuary Coolers' purpose-engineered solution for the growing demand for bariatric decedent storage capacity. As average American body weights continue to increase, funeral homes and morgues that equipped themselves with standard-width coolers a decade ago are increasingly encountering cases that test — or exceed — those units' physical limits. The 4BX is the practical answer.

Why Bariatric Capacity Is No Longer Optional

The CDC reports that adult obesity rates in the United States now exceed 40%. For funeral home directors, this translates directly into decedents whose shoulder width and total mass exceed what standard mortuary cooler trays were designed to accommodate. A standard-width tray that worked adequately for the average 1990s decedent may be inadequate for a meaningful percentage of 2026 intakes in many markets. Facilities that wait until they have an active bariatric case to address this gap face the worst-case scenario: an oversized decedent, inadequate equipment, and no immediate solution.

Model 4BX Extra-Wide: What Is Different

Extended Interior Tray Width

The 4BX features wider interior tray dimensions than the standard 4-body configuration — specifically engineered to accommodate decedents with broader shoulder widths and higher body weights. Tray reinforcement is upgraded to handle the weight differential without flex or slide failure. Each tray extends fully for body placement and retrieval.

Reinforced Door & Frame Construction

Wider trays require a wider door opening and corresponding frame reinforcement. The 4BX door assembly is engineered to the same tight-seal standard as standard-width units — maintaining the thermal integrity that CDC 34°F–38°F compliance demands — while accommodating the wider tray clearance required for bariatric cases.

CDC-Compliant Refrigeration

Wider interior volume requires proportionally more refrigeration capacity to maintain the same temperature stability. The 4BX uses an upsized commercial-grade compressor specifically matched to the expanded interior — maintaining 34°F–38°F in ambient environments up to 95°F without the temperature recovery delays that occur when standard-sized compressors are paired with oversized interiors.

4BX vs. Standard 4-Body: When to Choose Which

If fewer than 20% of your annual cases involve decedents over 300 pounds or with above-average shoulder width, a standard 4-body mortuary cooler with occasional alternative handling procedures may be sufficient. If bariatric cases are a regular occurrence — or if you want to future-proof your facility against the demographic trends — the 4BX is the more defensible long-term investment. Browse the full bariatric mortuary cooler collection for all available configurations.

Roll-In Bariatric Alternative

For facilities where the primary challenge is not tray width but body transfer ergonomics — specifically the two-person lift required to place a 400+ pound decedent on a standard tray — a roll-in mortuary cooler at the bariatric capacity tier may be the better solution. Roll-in units allow the cot to deliver the decedent directly into the cooler without any lift. Discuss your specific operational scenario with our team at 1-888-792-9315.

OSHA Ergonomic Compliance for Bariatric Cases

OSHA's general duty clause requires employers to provide a workplace free from recognized hazards — and the manual lifting of bariatric decedents is a well-documented ergonomic hazard in the funeral service industry. Investing in a 4BX or roll-in bariatric unit is not only operationally smart; it is a defensible OSHA compliance investment. Review our compliance roadmap and the detailed Mortuary Cooler Compliance guide for applicable OSHA standards.
