SHF-01939 4-Inch Caster Roller Wheels for HCD Shelving Unit, Set of Four,Black

They work and fit these old shelving units. 5/16 standard SAE thread on the studs. Had to use a tap on the shelving poles since they had been stored where the threads had gotten dirty and rusted. Note that only two of the 4 have brakes, do have some thought as to where to place where the brake levers will be readily accessible. Comes with one sheet metal wrench to fit the hex on the studs. It works and was needed due to the poor thread condition on the old supports. Worked well enough. All 4 casters installed and tight. Took about a half hour to install the set, mostly cleaning pole threads. Need to clear a spot off to erect the whole unit.

These caster wheels are excellent quality! They roll smoothly and quietly, making it easy to move furniture, carts, and other heavy items with minimal effort. The construction is solid and durable, holding up well even under heavy loads. Installation was quick and hassle-free, and the wheels lock securely when needed. Whether you're upgrading an office chair, workbench, or storage unit, these wheels are a perfect choice. Highly recommend for stability, durability, and ease of use! True FIT.

Used with 5 shelf steel shelving unit made by the same company. Instantly made stationary shelving mobile for cleaning under / behind them or allowing ready access to items in storage units or other areas where space is constrained and access might otherwise be limited. I was able to add these casters with little effort (everything needed was included). Afterward, I loaded up the shelving unit with items and easily wheeled the stocked unit to my storage unit with limited effort. Just be sure to match the correct size caster with the appropriate shelving unit so that the diameter of holes in shelving unit poles and threaded posts that screw in to attach the wheels to the shelving unit are of compatible diameter so that they align. Be sure that the caster is the appropriate size for the unit's weight bearing capacity. Once in place, two of the wheels can be locked if needed. This is likely to be very handy if floors are not perfectly level or when moving in future as the entire unit can be rolled onto a (larger) moving truck and secured (with both wheel locks and appropriate placement of straps). These shelving units were previously used primarily in garages and basements but have become widely accepted in kitchen and living areas with the advent of contemporary "industrial design" decor. You can even buy shelf coverings of plastic or wood to allow for flat surfaces and keep items balanced and / or from falling through the spaces between the rods that form the base of each shelf. If you didn't initially recognize the benefit of casters and you did not buy a wheeled shelving unit initially -- this is the fix!

I like these sturdy, threaded 4" caster roller wheels that easily screw into the bottom of wire shelving unit poles. I have bought these caster wheels 6 times so far--every time I get a new wire shelving unit. I have multiple wire shelving units in the house and garage and all of them are mobile. It's much easier to vacuum or wash the floor if you can move the shelving out of the way. Also, if you don't have a lot of space, mobile shelving can make your life easier since you can place the shelving units close together and just pull out the one you need. In the house, I have one mobile shelving unit for my small kitchen appliances--vacuum sealer, mixer, dehydrator, air fryer, crockpot, and baking pans and another for canned goods, cereals, crackers, condiments, jelly, etc. In the garage, I use one shelving unit to store holiday lights and decorations, and another for my tool box, drill, painting supplies, gardening implements, etc. I also hang S-hooks off my mobile wire shelving units to hold my leaf blower and weed whacker.

They are hard plastic, which is good for me. I attached them to a mobile bike rack from Harbor Freight. My 29er mountain bike was too tall for the rack and the back wheel dragged on the floor. The stock wheels were 2”, these 4” did the trick. This raised it up enough to lift the bike off the floor. They do not come with nuts. They also come with a flat wrench, but the smaller nut is NOT the right siZe for any wrench (like. 13.5mm). Luckily, the big nut I could grab. It was also sort of self-tightening anyway.

Built to last , no nose, no squeaks , no problems!

Easy upgrade if you want to be able to replace the leveler. Supplied wrench is a joke since it is a 14mm and the nut is 9/16 standard but it needs to be thin to work and tge supplied wrench will tighten it ok. Easy rolling ofvthe shelving unit once installed. Two of the wheels have locking levers.

Very easy to put on

Los use con estantes de Home Depot y quedaron perfectos

These are great casters. I bought them to use on uline chrome wire shelving units. They fit perfectly and are a breeze to install! Would definitely recommend!

Se sienten de excelente calidad, le quedan perfecto a los HDX de Home Depot.

I got my set for $25 ... I have owned these for over a year and a half now... These casters can be used for anything not just the shelving. The quality is great, smooth solid wheels, supports a lot of weight without breaking or flaking. 2 of the wheels have a locking mechanism which is great... I am very happy with this product!

I bought these some time ago to use on a 4-shelf chrome rack from the tire store but never got around to unloading the rack to install them. This past week I bought some Trinity Bronze 4-shelf racks from the big box membership store, deciding to turn two racks into three racks using the inner rods to support the middle 'rack'. So instead of 3 separate racks using 12 uprights, I have one long joined rack using 8 uprights. That left me with f4 unused uprights and 2 shelves leftover. I decided to do a half height rack, and discovered these wheels fit the uprights. While installing the wheels, whilst taking it easy on my recliner, the entire thing slid back giving me a table . Eureka! Grandpa has a table for his recliner. Slides right under. It's a tad wobbly with the trays both at the 24-28" height but it works great. And far cheaper than anthing I've been seeing.
