REVIEW SUMMARY for BS Series Inner Riser Base for MRK Racks - 42 Inch Depth
No reviews for this product
How do I know which base is right for my rack?
Different racks require different caster bases to ensure an exact fit. The correct base is determined by the series of the rack or cabinet as well as its depth.

What is the difference between commercial-grade and fine floor casters?
Most caster bases are offered in two styles: Commercial-grade and Fine Floor. Commercial grade casters are suitable for heavy-duty applications and can support more weight; Fine floor casters are constructed from synthetic rubber to protect fine and decorative flooring and can generally support less weight.
