Product Details
About This Caster - ER4X2TUM
Set this 4-inch E-line rigid on the back corners of a heavy non-marking cart, the TPU polyurethane caster whose firm maroon tread carries the load without flat-spotting and tracks straight where a rubber wheel sets and a hard wheel scuffs.
A TPR rubber wheel flattens under a heavy parked load and carries less; the Pemco TUM polyurethane tread on a polypropylene core carries the higher E-line load without setting and stays non-marking, while the rigid fork holds the cart straight behind front swivels. The roller bearing carries the load at a walk, the 4-inch diameter keeps the rear low, and the 4 by 4-1/2 top plate bolts to a flat deck. USA-made for fast shipping.
Ideal applications
- Back corners of heavy non-marking carts
- Loads that flat-spot a rubber tread at the low height
- Straight tracking that cannot scuff the floor
Skip the polyurethane wheel if the cart works near heat over 180°F or on oily floors; a phenolic E-line wheel bears oil and heat to 250°F where TUM softens.
Pairs with: the ES4X2TUMTBK swivel up front for a steer-and-track cart.
Wrong fit? Want a precision bore, or a brake? See the ER4X2TUMB precision ball and the ER4X2TUMTBK tread lock.
Also in this family: the ER5X2TUM 5-inch rigid, or the full Pemco 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.
