This image is for Plate Size and Hole Placement ONLY. IT DOES NOT DEPICT THE ACTUAL PLATE.
We suggest that you do NOT drill the mounting holes to attach the casters until you receive them.
We do NOT include mounting Hardware.
You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.

Deduct 1/4 lb. for weight of rigid caster.

Use the Polyolefin ( Industrial Plastic ) wheel for "Standing Loads". Polyolefin wheels eliminate the possiblilty of a flat spot developing if the castered equipment is left parked for a prolong period.

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 casters are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
