4" x 1-1/4" Rigid Caster | Polyolefin Wheel | 300 lbs Capacity | Plate Size: 3-1/8" x 4-1/8"Industrial Plastic (Polyolefin) Wheels also known as Polyolefin Caster Wheels are injection molded from a blend of polyolefin/polypropeline polymers forming a one piece design that is solid and will not de-laminate. Polyolefin Wheels are great for wet and corrosive environments while providing a high impact resistant wheel. Polyolefin wheels are more economical compared to aPhenolic Wheel or a Steel Wheel. These wheels are not affected by chemicals, solvents, oils, blood, grease, and will not absorb water. These wheels are non-marking and light in weight. Black is the standard color on plastic wheels. Industrial Polyolefin Caster Wheels are a great choice if your on a budget but need new wheels. These are not great when rolling over obstacles or debris such as cables or gaps, we would recommend a Thermo Plastic Rubber Wheel if you need more grip to roll over obstacles and debris.
