Expandable Stem Caster

AstraRoll Expandable Stem Casters are specially engineered for simple, tool-free installation in open tubing fixtures. Designed with a hex nut below the caster raceway, these casters allow the internal rubber adapter to expand tightly when the nut is rotated, creating a secure and stable fit inside both round and square tubing. Highly versatile in application, these expanding stem casters are widely used on carts, storage racks, equipment stands, cabinets, and various tubular furniture. By adding reliable mobility to these items, they greatly reduce the effort required for moving and repositioning equipment in daily operation. AstraRoll provides a full range of expandable stem casters in different sizes and load capacities to suit light, medium and heavy-duty requirements.
