    • Hamilton MDD Maxi-Duty Dual Wheel Casters

    Capacity Range: 5,000 – 16,600 lbs.

    Casters and wheels all serve a specific purpose, so all manner of operations function smoothly. That's why our dual-wheel series version of the Maxi-Duty Caster was developed to address the issue of restricting overall height while still providing supportive carrying capacity. These new Dual Wheel Hamilton Casters have convenience and functionality in mind, featuring treaded wheels that improve stability and swivel more easily than wider-face single wheels since they don't cause the same "scrubbing" effect.

    When it comes to the brands that we represent, we want to make sure our clients get the most out of each product. If you're looking for precision, then the Dual-Wheel Casters are your best bet. The best part? HPI™ Swivel Technology is the standard feature in this dual-wheel series, providing better performance, longer life, and smoother movement. Call us for more information about our casters and products.

    If you need dual-wheel casters for lighter duty applications, see our EHD2 series.
