The Thermo-Pro wheel is a non-marking grey thermal rubber bonded to a polyolefin core. Resistant to cleaning chemicals, acids, alcohol and water. Used in many hospitals, seafood plants and restaurants, normally where there is either food preperation or delivery. Also a favorite choice for industrial linen facilities.

As part of the 21 Series, this caster features a 1.25 Inch wide wheel in a dual ball bearing raceway. The 21 Series comes standard in Bright Zinc Plating with a dust cover.

    I run the YWCA food bank in central Seattle and needed rolling carts for our clients food bags. The casters on the carts I purchased couldn’t handle the weight of the food bags (700+lbs) and failed. When I reached out to Caster Solutions for advice, they responded within an hour. Greg was extremely helpful in understanding my problem and finding exactly the right caster for the job. Then to top it off he offered to donate them (enough for 8 carts!) in support of our work. This was above and beyond and totally unexpected, thank you! So if you want to support a great local business, that provides excellent customer service and cares about it’s community, this is the place!!
