Product Details
About This Caster - D4.06108.551 SS
Use this 6-inch Defender D4 rigid for a quiet cart that has to clear thresholds easily and run maintenance-free.
The taller 6-inch round-tread Performa rubber wheel rolls over door tracks and floor joints with the least effort while staying quiet and non-marking on finished floors, its rounded profile keeping rolling resistance low. The Delrin plain bearing runs grease-free and corrosion-proof for sprayed-down rooms, on a stainless steel frame for corrosive bays. Soft rubber keeps the load class modest, so this is the quiet, easy-rolling, low-upkeep choice that also handles uneven floors, not a heavy hauler. Rigid means it tracks straight at the rear. It serves from -45 to 180°F.
Ideal applications
- Quiet 6-inch carts that must clear thresholds and uneven floors
- Maintenance-free 6-inch stainless rigs on uneven damp floors
- Straight-tracking rear corners clearing thresholds on a soft tread
Keep the load light for soft rubber and confirm the 7-1/2-inch mount height suits the taller wheel before ordering.
Pairs with: a matching Defender D4 swivel up front so the cart steers while this rigid tracks straight, from the Colson collection.
Wrong fit? A 5-inch wheel fits better? See the 5-inch Performa round Delrin rigid D4.05108.551 in the Colson collection.
Also in this family: the 6-inch polyolefin Delrin rigid D4.06108.831, 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.
