Compare capacity and fit
Product | Documented difference | When it fits |
|---|---|---|
Keter City 30-gallon box | 30 US gal; 22.7 in exterior width. | Small items and limited floor space; measure first. |
Suncast 50-gallon deck box | 50 US gal; 36.75 in exterior width. | More storage volume if the 34.25 in interior width fits your items. |
Keter Westwood 150-gallon box | 150 US gal; large chest format. | Larger sets of items after checking usable dimensions for 243528. |
Start with what must fit
Consider City for small accessories when floor space is limited. Suncast provides more volume and a wider interior for items that fit its documented dimensions. Westwood offers 150 gallons for larger sets of items, provided the exact box fits your patio and its interior fits the contents.
Nominal gallons compare volume, not cushion compatibility. Measure the longest item, the opening and the usable interior. Leave room above and behind the box to open the lid.
Check the exact version and placement
The selected Westwood is dark grey, part 243528. Do not substitute the dimensions of the current grey shop reference 263749. Confirm the exact part’s dimensions before ordering.
Follow assembly and placement instructions. Weather resistance does not mean a sealed container or guarantee that contents stay dry in every condition. Choose by fit and storage need; none is an absolute winner.
