Consult Acorn® for more
information and specifications.
•
All FOUR-IN-ONE caster jacks can be furnished with or without the casters. Special care must be taken when selecting your caster requirement to make certain you do not exceed the maximum allowable caster size specified for each individual caster jack assembly. Usable size load capability is a factor of the rated load, overall height and the swivel offset of the caster assembly selected. Kingpinless casters with Nylacron® wheels are recommended for all caster jacks. For application assistance, contact Acorn®. Custom Caster Jacks Available. Consult Acorn® for more information and specifications.
