Quick answer
Worth it if you already have a rotisserie on your kamado and want it to do more than chickens. It clamps fish, wings, ribs or vegetables between two grids and turns them over the coals without you flipping anything by hand. Before ordering, check your spit profile (12/10 mm hexagonal or 10/8 mm square) and assume the listing is machine translated.
A rectangular stainless steel basket, 35.3 x 19 x 5.6 cm, that slides onto the rotisserie spit and turns with it. Takes 12 and 10 mm hexagonal spits and 10 and 8 mm square ones. Not tested: a reading of the listing and geometry.
The Onlyfire 6042 (part number F-BRK6042-SS1-EU in the details table) is a flat, polished stainless steel basket that a rotisserie spit passes through and turns with it. The listing gives 35.3 x 19 x 5.6 cm for the basket and 41.2 cm overall including two end pieces it calls "toldes", without saying whether they are handles or the closing tabs. No lid, rectangular, dishwasher and oven safe according to the manufacturer. The spit runs through the lower part of the basket and a wing nut locks it; the tabs open and close without tools. The weight is not published.
Its reason to exist is simple: a kamado rotisserie gets bought for chicken and gyros, and there it stays, because almost nothing else holds together skewered on a bar. A whole sea bass falls apart, wings drop off, ribs spin loose. The flat basket clamps the food between two grids: every turn presents one side to the coals and the fat drips away without you opening the dome. The listing names fish, sausages, chops, ribs, kebabs and vegetables. If you already make the [rotisserie chicken gyros](/recetas/gyros-pollo-asador-giratorio-kamado), this is the way to use the same motor for [crispy wings](/recetas/alitas-pollo-crujientes-kamado); bank the charcoal to the sides or set a drip tray under the spit, because fat from wings and ribs dripping onto live coals flares up.
On compatibility the listing is precise and silent at the same time. Precise about the spit profile: 12 or 10 mm hexagonal, 10 or 8 mm square. Silent about models: it names no rotisserie at all, not even the catalogue's two rings for a 46 cm dome, the [Onlyfire BRK-6064 for the Big Green Egg Large](/accesorios/onlyfire-brk-6064-asador-giratorio-bge-large) and the [JoeTisserie Classic](/accesorios/kamado-joe-joetisserie-classic), so measure your rod with a calliper before buying. As for room, the 41.2 cm overall length in a 46 cm chamber leaves about 2.4 cm a side (our estimate): tight, but enough as long as the motor coupling does not eat into the ring. The turn is less of a worry than it looks: the spit passes through the inside of the base and the basket sits centred on it, so the farthest point is half the width (9.5 cm) plus the 5.6 cm of height, a radius of about 11 cm (our estimate). That is the clearance you need towards the charcoal and towards the dome. On a 61 cm Big Joe or XL there is room to spare; for a 33 cm kamado there is no rotisserie ring in the catalogue.
The drawbacks are almost all in the listing itself. It is machine translated: the rotisserie spit comes out as "barra de la escupida", spit in the saliva sense, and something at the ends is called "toldes". It publishes no weight, no rod thickness and no maximum load, it labels the 19 cm of a rectangular piece as a "diameter" and ticks "lid: no" while giving stainless steel as the lid material. A basket full of ribs is heavy, and a modest rotisserie motor may feel it: the listing gives no figures and neither do we. When we read it, the listing showed as unavailable; Onlyfire is a marketplace brand, so check it is back before counting on it. In its favour, 4.5 out of 5 from 765 ratings and number 7 in Amazon.es housewares baskets: buyer opinions, not a test.
Verdict: a cheap accessory for what it is, well thought out for anyone who already has the motor turning and wants more out of it, on condition that you measure the spit first and read the listing with a magnifying glass, because whoever wrote it did not.
Opens the rotisserie to everything you cannot skewer. Well thought out and cheap for what it is; check your spit profile and do not ask the motor for what the listing never promises.

- Polished stainless steel, dishwasher and oven safe according to the listing
- 4.5 out of 5 from 765 ratings and number 7 in Amazon.es housewares baskets
Cons
- Machine-translated listing: no compatible rotisseries named, no weight, no maximum load

Who it's for
For anyone who already has a rotisserie on a 46 cm or larger kamado and wants to turn whole fish, wings, ribs or vegetables without skewering them or flipping them by hand.
Not for
Without a rotisserie it is no use at all, and if your spit is not 12/10 mm hexagonal or 10/8 mm square, likewise. For fish without a rotisserie, a folding fish basket does the job.

Onlyfire BRK-6064: rotisserie kit with pizza ring for the Big Green Egg Large
This is the same maker's rotisserie for the 46 cm Big Green Egg Large, and the natural partner for this basket if your kamado is a BGE. Onlyfire does not say in the basket's listing that the BRK-6064 spit is one of the four accepted profiles, so check the rod before buying both; if it fits, one motor does chicken, gyros and now fish and ribs as well.

Kamado Joe JoeTisserie Classic — Electric Rotisserie
Kamado Joe's rotisserie for the 46 cm Classic is the other ring in the catalogue this basket makes sense with. The basket's listing does not name the JoeTisserie, so measure the rod: if it is 12 or 10 mm hexagonal, or 10 or 8 mm square, the basket slides onto the same motor and multiplies what you can turn without buying another accessory.

Weber 17896 – Premium Leather Gloves for Embers and Hot Grates
Unloading a basket that has just been turning over the coals means grabbing hot steel by the tabs and loosening a wing nut with your fingers. Thick leather gloves spare you the silly burn you get with an oven mitt, and let you hold the basket firmly while you open it over the board rather than over the fire.

FAQ
Does it fit the JoeTisserie or Onlyfire BRK-6064 spit?
The listing names no rotisserie, neither the JoeTisserie Classic nor the BRK-6064: it only says it takes 12 and 10 mm hexagonal spits and 10 and 8 mm square ones. So measure your spit with a calliper or check the manual. If it is hexagonal or square and falls within those four sizes, it fits; if it is round or another thickness, it does not. The wing nut does not turn one profile into another.
Will it turn inside a 46 cm kamado?
Lengthways, just: 41.2 cm overall in a 46 cm chamber leaves about 2.4 cm a side (our estimate). As it turns, the basket sits centred on the spit, so the farthest point is half the width plus the height: a radius of about 11 cm. You need that clearance towards the charcoal and towards the dome. On a Big Joe or an XL there is room to spare; on a 46 cm it depends on ring height. Turn it once by hand, empty, before lighting.
How does it differ from the hexagonal tumbling basket in the catalogue?
The ivtivfu tumbling basket is a closed drum you fill with potatoes, wings or chopped vegetables and it tosses them loose inside, like a cement mixer. The Onlyfire 6042 is flat: it clamps the food between two grids and keeps it spread out, so it suits pieces you cannot let roll, such as a whole fish, ribs or chops. The Onlyfire needs a motorised rotisserie; the ivtivfu has a removable handle, so check its listing for whether it rolls on the grate by hand or mounts on a spit.
How do you clean it after fish or ribs?
The details table marks it dishwasher safe, and being stainless steel it needs no oiling or rust protection the way cast iron does. Burnt fat and fish skin stuck to the grid come off more easily with a soak in hot water and a soft brush before it goes in the machine. Release the tabs and open the two grids to reach the rod crossings; the wing nut only locks the spit. Dry it properly and check that the wing nut still tightens.
