Product Details
About This Caster - D4.04108.835 RW SS
Put this 4-inch Defender D4 rigid on the back corners of a sterilization or retort cart that runs through steam and high heat all day.
The frame is stainless steel, built for the wash-down and corrosive conditions that rust a plated caster, and the wheel is Colson's blue hi-temp polypropylene retort tread, made to ride through autoclave and food-processing retort cycles where heat and steam would melt or soften an elastomer. It holds from -45 to 250°F and resists the chemicals used in sterile processing. The pedestal precision ball bearing keeps it rolling smoothly at speed and on tow lines. Being a hard plastic wheel, it offers no cushioning and can mark a soft finished floor, so this is a heat-and-chemistry caster, not a quiet one. Rigid means it tracks straight rather than steering.
Ideal applications
- Retort and autoclave carts cycling through steam and high heat
- Stainless sterile-processing rigs that rust a plated caster
- Straight-tracking back corners on faster tow-line carts
Pair this rigid with a matching swivel up front and confirm the 5-5/8-inch mount height and bolt pattern before ordering.
Pairs with: the hi-temp Delrin rigid 49G41H42G-02 on lighter, grease-free wash-down lines.
Wrong fit? Carrying heavy loads slowly? See the hi-temp roller rigid 49G41I42G-02 in the Colson collection.
Also in this family: the white-nylon rigid 49G4G42G-02 for chemical service under 180°F, 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.
