Frequently Asked Questions
Why choose a 3-1/2 inch wheel? ›
The 3-1/2 inch sits between the 3-inch and 4-inch, offering better obstacle clearance than 3-inch while keeping total height lower than a 4-inch. Great when space is tight.
Is this caster non-marking? ›
Yes. Same gray thermoplastic rubber tread as all CasterHQ TPR casters — non-marking and quiet on all hard floors.
Can I mix 3-1/2 inch with other sizes? ›
Mixing wheel sizes on the same cart is not recommended as it creates uneven height. Choose one consistent size across all corners.
