3" & 4" Casters
3-inch and 4-inch overstock caster wheels suit low-clearance carts, tight maneuvering, and lighter loads on smooth floors. Browse verified surplus and closeout small-diameter casters priced below MSRP.
When to choose 3"–4"
Smaller wheels lower the deck height and tighten turning, ideal for under-counter carts, displays, and compact equipment. They carry less per caster and need cleaner floors than large wheels, but roll quietly and fit confined spaces.
- Low deck height, tight turning
- Smooth, clean indoor floors
- Light to medium loads
- Soft tread for quiet, floor-friendly roll
Buying small-diameter overstock
Each listing shows wheel diameter and width, tread material, mount, capacity, and quantity, so you can match clearance and load before buying.
Do small wheels roll harder?
Yes — smaller diameter increases roll resistance and is more affected by floor debris. On rough floors, size up to 5"–6" or larger.
What loads suit 3-4 inch?
Typically light to medium duty. Check the per-caster rating on each listing against your equipment weight.
