Quick answer: Many Wesco bins can be kept in service by replacing a single bucket, lid or runner frame. Check the code moulded underneath your existing bucket and match it in the table below. The W64 double-bin models use two 32L buckets, the W52 double uses two 26L buckets, and the W40 double uses two 20L buckets. The W30 and W40T systems combine 20L and 10L buckets.
Which Wesco replacement bucket fits your bin?
Match your model, or the code from your old bucket’s base. Match the code, not just the litres: two buckets of the same capacity can differ in height, shape and rim.
| Your Wesco model | Buckets in the unit | Replacement bucket | Code on the bucket base |
| W64, W64D, W64DS Bio-Double | 2 × 32L | 32L bucket (W64BC) | 7878110-1 or M 8358 532-1 |
| W52 | 2 × 26L | 26L bucket (W26B) | 7878111-1 |
| W40, W40D | 2 × 20L | 20L bucket (W20B) | 7878003-1 |
| W40T | 1 × 20L + 2 × 10L | 20L (W20B) + 10L bucket (W10B) | 7878003-1 / 7571003-1 |
| W30, W30D | 1 × 20L + 1 × 10L | 20L (W20B) + 10L (W10B) | 7878003-1 / 7571003-1 |
| Pullboy Z drawer systems | 8L, 17L, 29L or 32L | 8L, 17L, 29L or 32L (W64BC) | 8L: M8366108-2 (anthracite; earlier grey 8366108-1) · 17L: 8366117 · 29L: M8366127 · 32L: 7878110-1 |

How do I work out which Wesco I have?
These three checks can help narrow down your Wesco model, even without the original packaging or invoice.
- Read the code under the bucket
Lift a bucket out of the frame and turn it over. Wesco moulds a part number into the plastic, such as 7878110-1.
- Measure the bucket
If the code has worn off, measure the height. The 32L bucket stands about 530mm tall, the 26L about 430mm, the 20L about 360mm, and the 10L about 340mm but noticeably narrower.
- Check how it’s mounted
If you open a hinged door and then slide the bin out, it’s base-mounted. If the cupboard front itself pulls out like a drawer, it’s door-mounted (W64D, W40D, W30D or the Bio-Double W64DS). Count the buckets, and you’ll have your model.
Wesco pull out bin models explained
Wesco pull out bins use different mounting arrangements depending on the model. Cupboard-mounted systems use a steel frame fixed to the cabinet floor, with full-extension ball-bearing runners that carry removable buckets out to you. Pullboy Z systems instead sit inside compatible kitchen drawer hardware (see below).
- Base-mounted doubles (W40, W52, W64). The bin slides out after you open a hinged door, so nothing changes on the cupboard front.
- W30A double-bin option. The Wesco W30A has two equal 15L buckets, unlike the W30 and W30D models, which combine 20L and 10L buckets. It offers another waste-separation option for buyers comparing 30L systems.
- Door-mounted doubles (W30D, W40D, W64D, W64DS). The cabinet front is fixed to the bin, so one pull opens everything.
- Triple-compartment systems (W40T and W52T). These divide waste into three containers, which helps separate general waste, recycling and food scraps. The W52T listing describes one 26L bucket and two 10L buckets, a combined bucket capacity of 46L, although the product is marketed as a 52L model.
- Under-sink and narrow options. The W31 Shorty is designed for under-sink cupboards, at 330mm high to the lid and 345mm to the handle. Its 450mm width and your sink plumbing must be checked before installation; see our guide to what fits around under-sink plumbing. The W32S is a single 32L bin just 260mm wide.
Still choosing between brands? Our best pull out kitchen bins guide ranks the options by cabinet type and budget.
Which Wesco size fits my cabinet?
Check four measurements before you order:
- Internal width between the cabinet sides, allowing for hinges and face frames.
- Depth for the frame and runners.
- Internal height for the buckets, plus room to lift them out.
- Opening clearance, so the bin extends without hitting the door or nearby cabinetry.
Our guide to the minimum space a pull out bin needs explains each one.
| Typical cabinet size (confirm the clear opening) | Wesco models that fit | Total capacity |
| From about 300mm nominal | W30, W30D (unit 265mm wide), W32S (260mm wide) | 30–32L |
| From about 400mm nominal | W40, W40D, W40T, W52, W52T, W64, W64D (frames 345mm wide) | 40–64L |
| Selected 400–500mm cabinets with compatible drawer hardware | Pullboy Z drawer systems | Depends on configuration |
Cabinet sizes are a general guide, not a guarantee of compatibility. Always compare the clear cabinet opening and usable internal dimensions with the installation specifications for your chosen Wesco model.

What is a Wesco Pullboy Z?
Pullboy Z is Wesco’s drawer-integrated system: the bins sit inside a soft-close kitchen drawer behind a matching drawer front. Wesco’s Australian distributor, Wilson & Bradley, lists configurations for Blum TANDEMBOX, LEGRABOX and MERIVOBOX drawers.
How do I replace a Wesco bucket, lid or frame?
- Lift the old bucket out by its handle and drop the new one in, no tools needed. If both buckets in a double are cracked, order two.
- The Wesco replacement lid in our Replacement Buckets range suits the W64, W52, W40, W32, W40D and W40T.
- Runner frame. If the bin becomes hard to slide or looks misaligned, check for obstructions and loose fixings before forcing it. If the frame or runners are worn or damaged, replace the frame. The Wesco replacement runner frame fits the W64, W40, W52 and W32. Unscrew the old frame and fit the new one in the same position; our pull out bin installation guide shows each step.
Repair or replace? If the frame and runners remain in good condition, replacing a damaged bucket or lid can be more economical than buying a complete new bin system.
Grey, anthracite and hard-to-find parts
Selected Wesco Pullboy Z replacement buckets are now supplied in anthracite instead of grey; our 17L listing, for example, identifies the grey version as obsolete. Check the replacement’s part code, dimensions and stated compatibility before ordering, as colour alone doesn’t confirm a match.
We also list a Wesco 40L bucket (W40B), 420 × 224 × 505mm. Contact us to confirm the fit.
Spares for the stainless steel models (W32S/S and W40S/S) and the W31 Shorty’s 15L buckets aren’t currently listed. Contact us with your model and a photo of the part, and we’ll tell you what’s available.

Frequently asked questions
Can I replace one bucket, or a bucket with a broken handle?
Yes. Buckets are sold individually, so a cracked bucket or one with a failed handle can be swapped on its own without touching the frame. Match the part code underneath first.
Where can I buy Wesco replacement buckets in Australia?
Many owners find Wesco spares hard to track down locally. The Storage Online Shop offers a range of genuine Wesco replacement buckets, including 8L, 10L, 17L, 20L, 26L, 29L, 32L and 40L options. Check individual product listings for availability and compatibility.
My cupboard has a hinged door. Can the bin pull out when I open it?
Not with a base-mounted model: the W40, W52 and W64 slide out separately once the door is open. For a bin that follows the cupboard front, choose a door-mounted model such as the W40D or W64D, which replaces the hinged door with a pull-out front.
Which Wesco fits a 400mm or 600mm cupboard?
Selected W40, W52 and W64 models are designed for cupboards from approximately 400mm nominal width. They may also be installed in wider cabinets, including 600mm units, provided their mounting requirements, clear opening, depth and height are suitable.
My sink plumbing is in the way. Will a Wesco still fit?
Measure the clear space under and in front of the waste pipe. The W31 Shorty, at 330mm high to the lid, suits lower clearances; taller doubles need the plumbing to sit behind the bin. If nothing fits, a plumber may be able to reroute the pipes.
What size bin liner suits a Wesco 32L bucket?
A 30L kitchen bin liner is recommended for the W64BC 32L bucket. Liner sizes and rims vary between brands, so check the bag sits securely over the bucket opening.
Final Thoughts: Choosing the Right Wesco Bin
Whether you’re installing a new kitchen bin or replacing a damaged component, the right choice starts with accurate measurements and model compatibility. Compare the available Wesco pull out bin options based on your cabinet space and waste-sorting needs, and always check the original part code before ordering replacement buckets.
