20ft Storage Container w/ Roll-up Doors

Product overview

A 20ft used storage container w/ one 7ft roll-up door on the left side — also called a 20-foot conex container or sea can — is a cost-effective steel storage unit for sale with left-side ground-level access. At 20ft (20-foot) long, it balances capacity and footprint, and the left-side 7ft roll-up door lets you load from the side that best matches your driveway, fence, or adjacent building.

Why choose used with a left-side door? You save compared to new while still getting inspected, structurally sound Corten steel and a 5-year structural warranty. The 7ft roll-up opening beats end cargo doors for hand trucks and pallet jacks, and used units may show minor cosmetic wear that does not affect weatherproof performance.

Ideal for residential storage, contractor supply cribs, retail backstock, agricultural equipment, and secure on-site staging. No hidden fees, and Conexwest offers lockboxes, shelving, and custom modifications. Units are in stock for nationwide delivery and available for online purchase today.

Secure, weatherproof, and in stock nationwide. Order your 20ft used storage container with a left-side roll-up door online now — delivered in 3-7 days across the US. Pricing, specs, and FAQs are in the product tabs. Order online for fast nationwide delivery.
