Stainless Steel Grid Built to Protect 330 Series Bowls
The Karran GR-3006 is a rectangular bottom grid made specifically for the 330 Series sink, sitting on the bowl floor to keep dishes, pots, and cookware from making direct contact with the sink surface while water drains freely underneath.
Key Features
• 330 Series fit: Sized and shaped to match the bowl of the E330 and compatible 330 Series sinks exactly.
• Stainless steel construction: The grid's wire frame resists the moisture and wear of daily kitchen use.
• Elevated basin floor: Raises dishes off the bowl bottom so water and food debris drain away rather than pooling beneath your load.
• Rectangular profile: Matches the geometry of the 330 Series bowl without gaps or awkward overhangs.
• Sold separately: A standalone accessory; order the correct GR number for the bowl you're protecting.
The Case for a Fitted Grid in a Hard-Working Sink
A stainless sink takes a beating from cast iron pans, ceramic bakeware, and the constant scrape of utensils. The GR-3006 gives the 330 Series bowl a layer of separation between those surfaces and the finished steel below. Because the grid's footprint matches this bowl specifically, it sits level and stable rather than rocking or shifting during use. Drainage channels built into the wire layout let water move freely to the drain, so there's no standing water trap beneath the rack after dishes are cleared.
Material and Construction
Stainless steel wire construction means the grid handles the same wet, acidic, and soapy environment the sink itself lives in. The rectangular form follows the 330 Series bowl's geometry closely, which is what separates a model-matched grid from a generic store-bought rack that bridges the rim or leaves wide gaps at the corners. Tight corner fits matter when you're stacking bowls or setting a cutting board to rest at an angle.
Who This Grid Is For
Cabinet shops installing the E330 in a new kitchen build, homeowners who have already taken delivery of a 330 Series sink, and contractors completing a renovation will all find the GR-3006 a natural complement to the sink. It's the kind of add-on that gets specified at the same time as the sink and then forgotten until something scratches the bowl floor. Ordering it alongside the sink removes that friction from the job.
How do I know this grid fits my specific 330 Series sink?
The GR-3006 is published for the E330 and the 330 Series family. If your model number includes E330 or is in the 330 Series, this is the correct grid. If you're working with a different Karran series, check the GR number matched to that model in Karran's fit tables, because grid fit is model-specific throughout the line.
Does this grid include rubber feet or bumpers to protect the bowl?
The source data does not confirm included feet or bumpers for this grid. Check the product spec block or contact Karran directly for that detail before assuming foot protection is part of the assembly.
Can I use this grid in a different Karran stainless sink with similar dimensions?
Karran's grids are fitted to specific models, not to general dimension ranges. Even when two bowls measure close on paper, bowl geometry, corner radius, and drain placement can differ enough to affect how the grid sits. Stick to the published fits-list for each GR number.
Is the GR-3006 included when I order the E330 sink?
No. The GR-3006 is a standalone accessory sold separately from the sink. Add it to your order at the same time as the sink to make sure both arrive together.
The Right Grid Makes a Fitted Sink Stay That Way
A bowl protected from the start holds its finish longer, and a model-matched grid is the straightforward way to get there — no trimming, no improvising, and no generic rack that shifts every time a pan goes in.
