Kegerator Caster Load Capacity: What Is Enough?

What caster load capacity means on a listing

Caster load capacity is the weight a single caster is built to support. On a kegerator listing, the term usually appears as one line in the bullet list or in the specification block, and it is the limit for one caster, not for the whole cabinet.

Most kegerators sit on four casters, so the combined support is the sum of the ratings when the weight is spread evenly across them. A per-caster rating is a useful number to compare, but the load inside a kegerator is not always balanced, so the rating is a guide to read alongside the cabinet size and tap count.

The listing may use other words for the same detail: 'weight capacity', 'load rating', or simply 'caster wheels' in the title. A title that says only 'caster wheels' tells you the unit has them; it does not tell you how much they can carry.

What is enough depends on the size of the cabinet and the keg it holds. A compact single tap unit has a lighter load than a wide multi-tap cabinet, so the capacity you need follows the size you choose. The guides for single tap and full size units let you compare the stated details across those groups.

How the weight adds up when a unit is loaded

A kegerator is sold as an empty cabinet. The casters carry more once the unit is loaded with a keg, the contents of that keg, the shelves, and anything else stored inside. The difference between the empty weight and the loaded weight is why the empty weight alone is not enough to compare two units.

A full keg is noticeably heavier than an empty one, and the tower and faucets add weight on top of the cabinet. When you read a caster capacity, think about the loaded weight you expect for the size of cabinet you are considering, not the weight of the empty unit. For the keg sizes a cabinet can hold, see keg size compatibility.

When you compare two listings, put the caster capacity next to the width and tap count. The pair that states a capacity that suits a loaded cabinet is easier to evaluate than one that does not.

Where to find the capacity in a listing

The caster rating is usually one line among the cabinet details in the bullet list. It may be phrased as a per-caster number or as a total for the set. Read the exact wording: 'per caster' and 'total load' mean different things, and a listing can state either one.

Images may show the caster, but an image does not state a rating. If the specification block has no capacity line, the detail is missing. The phrase 'not stated by the seller' means exactly that: the number is not available from the listing, and you cannot infer it from the cabinet width or the tap count.

• Check the bullet list for the words 'caster', 'wheel', or 'load'.
• Read the specification block for a capacity line.
• Look at the images for a label or diagram that names the rating.
• If none of these show a number, treat the detail as missing.

Why tap count and cabinet width matter

A cabinet with more taps carries a heavier tower and more hardware. A four-tap tower has more material than a single tap, and the same idea applies to cabinet width: a wider cabinet is a larger structure, and the load inside is larger as well. A listing that promises several taps or a wide cabinet should also show a capacity that matches that size.

You can compare the stated caster capacity across listings of similar width and tap count. A unit with a single tap and a compact width needs a lower rating than a wide cabinet with several taps, all else being equal. For guides on tap counts and widths, see dual tap kegerators and 24 inch kegerators.

The same reasoning applies to cabinet depth and the number of shelves, though width and taps are the details most listings give in the title.

Commercial kegerator casters

Commercial kegerator listings often name casters in the title, with words like 'mobile' or 'caster wheels'. A commercial title tells you the unit is built for repeated use, but it still must state the capacity for you to compare. Larger commercial cabinets carry more weight, so the caster detail is worth reading rather than skipping.

A commercial unit may also list locks on the casters, which is a separate feature from the load capacity. The lock holds the wheel in place; the capacity tells you how much weight the wheel can carry. For the difference, see caster locks and brakes.

• Commercial titles name casters as a feature.
• The capacity line still needs to be read separately.
• Locks and capacity are two different details.

What to ask when the number is missing

When a listing does not state the caster load capacity, the buyer has to ask. The questions are simple: is the rating per caster or for the whole set, what is the total for four casters, and do the casters lock in place. The seller or the maker's spec sheet may list the figure even when the listing itself leaves it out.

Before you commit, compare two listings side by side on the stated details. If one gives the capacity and the other does not, the one with the figure is easier to evaluate. For similar units, see the best kegerator guides and the guides for commercial kegerators.

A caster capacity that covers the loaded weight is the goal; a capacity that covers only the empty cabinet leaves no room for the keg and its contents. If the unit will move between rooms or to another area of the home, see leveling legs versus casters for how that choice affects your setup.

What to pick for your situation

Questions

What is caster load capacity?

Caster load capacity is the weight one caster is built to support. It is usually stated per caster, and the total for the cabinet is the sum of the ratings when the weight is spread evenly.

Is the rating for one caster or for the whole cabinet?

Read the exact wording in the listing. A 'per caster' rating covers one wheel; a 'total load' line covers the whole set. The two figures mean different things, and you need to know which one the listing gives.

What does it mean when a listing does not state the capacity?

It means the detail is missing. You cannot infer the capacity from the cabinet width or tap count, so the next step is to ask the seller or check the maker's spec sheet.

Does a full keg change the weight on the casters?

Yes. A loaded kegerator carries the weight of the empty cabinet, the keg, the keg's contents, and the tower. Compare the stated capacity against the loaded weight you expect, not the empty weight.

Do more taps mean more weight?

A tower with more taps carries more hardware, so a multi-tap cabinet weighs more than a single tap of the same size. The caster capacity should match the tap count and the cabinet width.

Should I compare the capacity across listings?

Yes, when the units are similar in width and tap count. A capacity number that is stated is easier to compare than one that is missing, and it is one of the details this site compares on stated details.
