6 in x 2 in Maroon PRO Polyurethane Top Plate Caster - 900 lb Capacity

In this review of the ICON 6660 Series single caster, the bottom line is straightforward: this is a heavy duty, industrial caster aimed at users who need a high load capacity and durable, non-marking wheels. The reviewer finds it best for workshop equipment, tool chests and industrial carts where a single caster must carry up to 900 lb safely. The maroon pro tech polyurethane tread and cast iron construction deliver long wear and chemical resistance, while the top lock brake and full 360 swivel provide practical control during use.

Key Features

• 900 lb load capacity: Each caster supports heavy equipment reliably, making it suitable for industrial tool boxes and machinery that demand robust wheels.
• Pro tech polyurethane tread: The maroon polyurethane protects floors from tread marks and offers resistance to oils, grease and most chemicals for cleaner environments.
• Polypropylene core: A sturdy core construction helps maintain wheel shape under sustained loads for longer service life.
• 360 swivel top plate: Full rotation makes maneuvering bulky items easier, allowing directional changes without repositioning the load.
• Top lock brake: The brake applies pressure to the top of the wheel to hold it stationary, useful for securing carts and tool chests during work.
• Industrial-grade materials: Cast iron core components and quality polyurethane deliver the strength and durability expected in heavy duty settings.

Who It's For

This caster is designed for professionals and serious hobbyists who move heavy loads in workshops, garages, warehouses or production areas. It is especially well suited for replacing worn casters on large tool chests, industrial carts, and equipment that require a reliable 900 lb capacity per wheel.

Those looking for very quiet, precision swivel performance for light-duty furniture or office chairs should look elsewhere; lighter-duty polyurethane or rubber casters with lower load ratings and different mounting styles will offer a softer ride and potentially quieter operation for delicate floors.

Pros & Cons

Pros

• High load capacity gives confidence when moving heavy tool boxes or equipment.
• Durable maroon polyurethane tread resists chemicals and keeps floors free of marks.
• Top lock brake and 360 swivel add practical control for stationary and mobile use.

Cons

• Rollability receives mixed reports; some users note excellent movement while others report occasional swivel lock issues, so check swivel function on arrival.
• Single caster purchase means higher-per-unit cost compared with buying a set if multiple casters are needed.

Frequently Asked Questions

Can one caster really support 900 lb?
Yes, the product is specified at a 900 lb maximum per caster, which translates to about 3600 lb for a typical set of four when load is evenly distributed.

Will the polyurethane leave marks on floors?
No, the pro tech polyurethane tread is non-marking and designed to keep floors clean while resisting oils and common workshop chemicals.

Does the top lock brake stop swivel rotation as well as wheel roll?
The top lock applies pressure to the wheel to prevent roll; it secures the wheel but may not lock the swivel mechanism fully on every installation, so verify stability after mounting.
