    Upgrades & Conversion Kits
    While W.E. Carlson would love to help you find a new, state-of-the-art piece of equipment to replace an outdated, unsafe or damaged one, upgrading or converting your existing equipment is another cost-effective option to increase safety and productivity at your facility. From dock levelers to doors to shelters, we can help improve your environment without starting from scratch—even if you’re using our competitors’ products! Many upgrades and conversions can be retrofitted to other manufacturers’ products—just ask!
