Product Details
About This Caster - 170RT04201S
Pick this 4-inch Empire 170 swivel when a cart needs to steer through a wet or high-heat area on a tough, low-cost plastic wheel.
The wheel is glass-filled polypropylene, a stiff reinforced plastic that handles -20 to 250°F and resists washdown chemicals and corrosion, a practical pick for caustic or humid areas where steel rusts and rubber breaks down. It is hard with no cushioning, so it rolls easily on smooth floors but passes shock through and can mark, and at 4 inches it carries up to 800 pounds on a roller bearing sized for manual pushing. The swivel turns on a kingpinless welded raceway with no central pin to loosen, bolts on a 4 by 4-1/2-inch top plate at a low 5-5/8-inch mount height, and wears a zinc-plated finish.
Ideal applications
- 4-inch economical Empire 170 black glass-filled poly swivel up to 800 lb
- Steering corners on washdown carts needing a corrosion-proof plastic wheel
- Maneuverable high-heat carts up to 250°F where rubber would break down
For a fixed wheel that tracks straight, the 170RT04201R is the rigid version.
Pairs with: two RT rigids on the fixed end and two of these swivels on the steering end of a cart.
Wrong fit? Need a brake or a softer ride? See the RT braked swivel 170RT04201SFBB and the soft 80A PM swivel 170PM08228S0180A.
Also in this family: the RT rigid 170RT04201R, or the full Albion collection.

What our customers say
Excellent service! Outstanding quality castors.
Great customer service and casters!
Great service, friendly staff and quality product.
Excellent all inclusive selection. Was able to use their product search to easily and accurately purchase two pieces of Seperate but related pieces of hardware. Product shipped and tracked per UPS and arrived in a timely manner while packaged and in good condition. Product quality is excellent especially given price was a very reasonable.
Purchased Blickle casters from W.T. Hight Company. Rated 5/5.
Long story short, we purchased an under-counter freezer that was too tall and needed the casters taken off. However, I had no idea how to do that so a quick Google led me to W.T. Hight and the customer representative, Lemuga, was super patient and walked me through the process! Although we didn't purchase anything this time, their customer service was wonderful and we will be keeping this company on our radar for all things casters!
I had an amazing experience with W.T. Hight Company! I purchased casters for my equipment, and the quality was outstanding — sturdy, reliable, and exactly what I needed. The customer service was top-notch; they were incredibly patient and walked me through the entire process to ensure I got the right fit. Highly recommended.
