Choose dual caster wheels that are strong enough for the job Not all casters can handle the weight of heavy-duty shop equipment or industrial-size machinery. While some are made for regular use around the office, others are made to tackle tough jobs around the factory. Picking the right caster's essential to maintaining the safety of your equipment and employees.

I recommend:  E.R. Wagner's Haydock Casters are stylish and great for the office. For a beefier product, consider industrial casters from Magnus Motion Control Solutions, the strongest of which support up to 30,000 lb.

Decide between rigid and swivel dual wheel casters While swivel casters provide the most mobility, they're not always necessary for moving your equipment. Objects that only move back-and-forth work well with rigid casters, which eliminate the jerky wobbling and sideways slipping characteristic of swivel casters.

I recommend:  Search Mr. Roller Inc.'s product catalog to find a wide variety of both rigid and swivel casters. For more control over your casters, use the online order application at Shepherd Casters to build your wheels from scratch.

Find multiple wheel casters that blend durability with grip Depending on your equipment's size, sensitivity and weight, you'll need to consider the compounds comprising your casters' wheels. Some wheels provide outstanding grip, but they may not be as durable as ones that are less sticky. Finding a balance between the two ensures you get the best functional value for your money.

I recommend:  Hamilton Caster offers two great industrial dual-wheel casters in six different wheel types. Caster Technology Corporation also offers an industrial-strength product in multiple varieties.
