Crain No. 075 (75 lb.) rollers now have zinc plated roller sections to help prevent rust, and come with a protective wheelie case. Constructed of solid steel to provide a lifetime of trouble free service. All models have rollers with smooth surfaces and rounded corners protect flooring materials from indentations. Each roller section "floats" independently on the axle to automatically compensate for subfloor irregularities. The end roller sections are recessed to inset the axle, preventing wall scuffing. The yoke has a detachable handle so that both may be carried separately.
