Built Different

🧊
Cold That Holds

Up to 80mm insulation in the lid and 40–45mm in the walls and base — thermal mass built to maintain temperature in high-demand environments.

🏗
Rotomolded Shell

Seamless one-piece polyethylene construction handles full commercial loads and harsh conditions. No joints to crack, no seams to leak.

🔩
Heavy-Duty Hinges

4 injection-molded hinges with a 90-degree stop keep the lid clear and stable while open.

🚿
Fast Drainage

Two large drain ports — one on each side — clear meltwater fast so you can wash down, reset, and reload quickly between hauls.

🧼
Hygienic Interior

Food-grade, non-porous internal lining resists odours and staining — easy to sanitise after seafood, game, or heavy commercial use.

Marine-Grade Neoprene Lid Gasket

A full-perimeter neoprene gasket forms an airtight, watertight seal — keeping cold in and water, dust, and odors out.

🔐
Southco Lid Latches

Premium UV-resistant Southco latches create a tight seal to lock in the cold and hold up in sun, salt, and harsh conditions.

🖐
Molded-In Lid Handles

Handles molded directly into the underside of the lid — no hardware to snag gear, corrode, or come loose.

📦
Volume That Means It

300 to 600 quarts — the cube format maximizes bulk load capacity where volume matters more than length.
