H03

HEAVY DUTY CASTER • UP TO 7,000 LB
5 1/4” x 7 1/4” TOP PLATE • KINGPINLESS RACEWAY 

6”- 12” Wheel Diameter  |  3” Wheel Width  |  Zinc Finish

Similar to H02 but with a larger top plate - this one is another go-to for heavy-duty applications that see significant load capacity. 3” diameter precision
machined and heat treated raceway with 3/8” thick steel legs. Due to the construction and size of the raceway bearings, this will be extremely easy
to swivel under load and will outlast kingpin-style casters.

Toe Guard

TO

Precision-machined in by Acorn® from ultrasound-tested, domestically made, cast polyamide. Floor-protective even under very high loads. Exceptionally long service life. Best-in-class ergonomics and extremely low rolling resistance under extreme loads. Resistant to chemicals, salts, greases, and acids (inquire for full compatibility list). Excellent for steam cleaning. Ideal for extremely high-load, low-speed applications as a durable alternative to metallic wheels. Non-marking.
