Core Advantages

✅ Quiet Brown TPR Wheel, Excellent Floor Protection

High‑elastic brown TPR running surface delivers ultra‑silent rolling. It will not scratch or leave marks on epoxy floors, tile, wooden floors and workshop ground. Wear‑resistant and anti‑aging for long‑term frequent use. Soft tread absorbs vibration when transporting goods.

✅ Galvanized Heavy‑Gauge Steel Bracket

Thick stamped steel bracket with electro‑galvanized finish for rust resistance. Precision double‑ball swivel raceway enables smooth 360° rotation without jamming. Rivet‑reinforced wheel assembly improves stability under repeated pushing and pulling. Multiple brake versions are available to meet different usage requirements.

✅ Flexible Size Selection & Stable Load Capacity

3/4/5‑inch sizes for different load demands. Compact structure, suitable for light‑to‑medium‑duty handling scenarios. Standard square mounting plate with universal hole spacing, easy to install and replace on various equipment.

✅ Practical Brake Design

Total lock brake option locks both wheel rotation and swivel movement. Once engaged, the caster cannot roll or turn, keeping carts and equipment firmly in position during operation.
