US Postal Service Casters
You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these wheels are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
These casters are designed for the 1046 canvas and the 1046P Plastic Postal Service Carts which are used to load postal delivery trucks.
