Product Details
About This Caster - D4.04108.839 RW SS WB29
Reach for this 4-inch Defender D4 rigid when a heat-service cart is loaded heavy and pushed slowly across the floor.
The roller bearing is the heavy-haul option here, carrying more weight than a ball or Delrin bearing as long as the cart moves at a deliberate pace, which suits a packed oven rack or retort trolley. It rides on Colson's blue hi-temp polypropylene retort wheel, a hard tread that comes through steam and high heat to 250°F and resists sterilization chemicals, on a stainless steel frame that stands up to the wet, corrosive bays this equipment lives in. The rigid mount holds a straight line at the rear of the cart. Because the wheel is hard plastic it gives no cushioning and can mark a soft finished floor, so weight and heat come first, not ride quality.
Ideal applications
- Heavily loaded oven and retort trolleys moved at walking pace
- Stainless high-heat carts in wet, corrosive processing bays
- Straight-tracking rear corners under sustained heavy pushing
Confirm the load stays within the roller-bearing class and the 5-5/8-inch mount height fits before ordering.
Pairs with: the hi-temp precision-ball rigid 49G41G42G-02 on the lead corners for smoother fast travel.
Wrong fit? Lighter, grease-free wash-down duty? See the hi-temp Delrin rigid 49G41H42G-02 in the Colson collection.
Also in this family: the white-nylon roller rigid 49G4I42G-02 for cooler service, or the full Colson 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.
