Open most under-sink cabinets and you’ll find the same scene: a spray bottle wedged behind the P-trap, a half-empty box of trash bags, and something in the back corner nobody’s touched since last spring. It’s not that people don’t want to organize this space — it’s that the space itself fights back. Pipes cut into the width. The door swings into whatever you put near the front. And unlike a normal shelf, half of it is invisible unless you get down on the floor.
A good organizer earns its keep by working with those constraints instead of ignoring them — pull-out tiers so the back of the cabinet isn’t a black hole, and a frame shaped to actually clear your plumbing rather than assuming an empty rectangular box.
We compared three popular 2-packs currently doing well on Amazon — Kitstorack, PXRACK, and Delamu — on construction, dimensions, adjustability, and what buyers report after living with them for a while.
Quick answer
Best for | Rating | Price | Standout feature | |
Kitstorack | Best overall | 4.6/5 | $45.99 | Heavy-duty metal, 2-tier pull-out |
PXRACK | Plumbing clearance | 4.6/5 | $46.99 | C-shaped frame, 5 height settings |
Delamu | Bathroom & small items | 4.4/5 | $25.98 | Clear drawers, movable dividers |
Ratings and sales figures reflect Amazon listings at time of research and can shift.
Short version: Kitstorack is the sturdiest all-rounder for kitchen cleaning supplies. PXRACK earns its place if plumbing or a garbage disposal eats into your cabinet space. Delamu is built for bathroom items you want to actually see — skincare, cosmetics, meds — not heavy bottles.
How we compared them: all three are metal-or-hybrid, pull-out, 2-tier systems sold in 2-packs, in roughly the same price bracket and footprint — which is what makes them worth putting side by side instead of against a random shelf. We looked at listed materials and weight capacity, height-adjustment mechanisms, and the pattern in verified buyer feedback rather than any single review.
1. Kitstorack 2-Pack — Best Overall
This is the one built like it expects to be loaded up and yanked in and out daily: carbon-steel frame, two pull-out tiers, 4.6 stars across 4,200+ reviews, 10K+ bought in the past month.
Specs:
5 height settings (≈13.8″–16.9″), 50 lb listed capacity, 11.8 × 15.9″ footprint, 4 suction cups, 2 adhesive films, 2-pack.
Nothing fancy about the mechanism — it’s a basket on rails — but that’s the point. Instead of unloading three bottles to reach the fourth, you slide the whole tier toward you.
Where it holds up:
Buyers consistently mention easy assembly, sturdy welds, and smooth drawer action. Several run one unit in the kitchen and the second in a bathroom.
Where it doesn’t:
A handful of reviews flag tipping risk if both tiers are extended fully loaded and the unit isn’t anchored — worth using the suction cups even if you’re tempted to skip them.
Skip it if:
Your cabinet is on the smaller side. At nearly 16″ wide and deep, it can crowd out plumbing in tighter cabinets.
Best for:
Kitchen sinks, cleaning supplies, laundry products, garbage bags.
2. PXRACK Large 2-Pack — Best for Awkward Plumbing
Take Kitstorack’s dimensions — 11.8 × 15.9″, up to 16.9″ tall, 5 height settings — and give the frame a C-shaped profile instead of a solid rectangle. PXRACK uses this shape specifically to leave clearance around under-sink plumbing.
4.6 stars, 2,100+ reviews, 7K+ bought in the past month.
Where it holds up:
Reviewers who deal with cramped kitchen plumbing specifically call out the C-shape as the reason they bought it over a flat two-tier shelf. Assembly and stability get the same praise as Kitstorack.
Where it doesn’t:
Adjusting the second shelf reportedly needs tools and partial disassembly for some buyers — more fiddly than a tool-free slide. One reviewer’s unit didn’t clear a garbage disposal and ended up repurposed in a pantry instead.
The lesson either way:
garbage disposals are one of the important fit issues to check before ordering.
Best for:
Kitchen sinks with plumbing obstacles, tall bottles, cabinets where a rectangular shelf won’t sit flush.
3. Delamu 2-Pack — Best for Bathroom Storage
Delamu isn’t chasing the same brief as the other two. Instead of a metal tier meant to haul cleaning bottles, it’s clear plastic drawers with movable dividers — four drawers total across the 2-pack, eight dividers, aluminum-alloy support rods, stackable.
4.4 stars, 7,800+ reviews, 8K+ bought in the past month — the highest review count of the three listings at the time of research.
Where it holds up:
Visibility. The metal baskets on Kitstorack and PXRACK make contents less visible, while Delamu’s clear drawers let you see smaller items immediately — and bathroom-sink reviewers say so directly.
Where it doesn’t:
Loaded with anything heavy, the drawers reportedly don’t glide as smoothly as the metal competitors — this isn’t built for a gallon of cleaner. One international buyer also reported missing dividers on arrival, worth a quick unbox-check.
Best for:
Bathroom cabinets, skincare, cosmetics, toiletries, medicine — lighter items you want to find at a glance, not heavy-duty capacity.

5 things that decide fit
- Usable width, depth, and height — not the cabinet’s outside dimensions, the clear space inside.
- Plumbing and disposal clearance — one of the most common fit issues in buyer feedback. Note where the drainpipe and disposal housing sit before ordering.
- Door hinges — make sure a fully-loaded organizer won’t stop the door closing.
- Pull-out clearance — you need room in front of the cabinet to actually extend the drawer.
- Compare your numbers to the listing — not the product photo. Photos don’t show your plumbing.
FAQ
Will an organizer fit around my plumbing?
Not automatically. Kitstorack and Delamu are solid rectangles; PXRACK’s C-shape is the one purpose-built to clear a drainpipe. None of them account for a garbage disposal by default — measure around yours specifically.
Do pull-out drawers actually make a difference, or is it a gimmick?
It’s a real usability upgrade over a fixed shelf — you’re no longer unloading half the cabinet to reach something at the back. The tradeoff is stability: fully extended and fully loaded, any of these can feel front-heavy if it isn’t anchored with the included suction cups or adhesive strips.
Metal or clear plastic — does it matter which I get?
For heavier bottles and cleaning supplies, Kitstorack and PXRACK are the more heavy-duty choices based on their metal construction and stated capacity/stability features. For lighter bathroom items where you want to see what’s what, Delamu’s clear drawers save more time than the extra weight capacity would.
Is buying a 2-pack worth it if I’ve only got one cabinet to organize?
Only if that one cabinet is deep enough for both tiers stacked, or you’ve got a second spot in mind — a bathroom, pantry, or laundry cabinet. Buying it purely because the per-unit price looks better than a 1-pack is how organizers end up in a closet unused.
Bottom line
Kitstorack is the strongest all-around pick for kitchens. PXRACK is the one to reach for when plumbing gets in the way. Delamu is built for bathrooms, not brute capacity. In every case, the organizer isn’t the variable that decides whether this works — your cabinet’s actual dimensions are. Measure first.
