Product Details
About This Caster - 170RT04201R
Pick this 4-inch Empire 170 rigid when you need a tough, low-cost wheel that shrugs off heat and chemicals on a straight-line cart.
The wheel is glass-filled polypropylene, a stiff reinforced plastic that handles -20 to 250°F and resists washdown chemicals and corrosion, which makes it a practical choice for wet or caustic areas where steel rusts and rubber breaks down. It is hard with no cushioning, so it rolls easily on smooth floors but transmits shock and can mark, and at 4 inches it carries up to 800 pounds on a roller bearing built for steady manual pushing. The rigid fork tracks straight only and bolts on a 4 by 4-1/2-inch top plate at a low 5-5/8-inch mount height, with a kingpinless welded raceway and zinc-plated finish.
Ideal applications
- 4-inch economical Empire 170 black glass-filled poly rigid up to 800 lb
- Washdown and chemical-area carts needing a corrosion-proof plastic wheel
- High-heat lines up to 250°F where rubber treads would break down
For a wheel that swivels instead of tracking straight, the 170RT04201S steers.
Pairs with: two of these rigids on the fixed end and two RT swivels on the steering end of a straight-line cart.
Wrong fit? Need to steer or want a cushioned ride? See the RT swivel 170RT04201S and the soft 80A PM line 170PM08228S0180A.
Also in this family: the RT braked swivel 170RT04201SFBB, 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.
