Stainless Steel Bottom Grid Built for the 520 Series Sink
The Karran GR-1002 is a rectangular stainless steel bottom grid engineered to fit the E520, E525, and E528 sink models. It sits on the bowl floor, lifting dishes and cookware off the surface so water can drain freely beneath while the sink stays protected during daily use.
Key Features
• Precision fit for the 520 Series: Designed specifically for the E520, E525, and E528 sinks, so it drops in without sliding or shifting.
• Stainless steel construction: The grid's material matches the stainless bowls it protects, resisting moisture and holding up through repeated use.
• Raised platform design: Elevates dishes and pots above the bowl floor so water drains continuously beneath rather than pooling under your load.
• Surface protection: Keeps the bowl bottom clear of direct contact with heavy cookware, reducing the risk of marking or abrasion over time.
Where This Grid Fits into the Workflow
In a busy kitchen, the bowl floor takes a beating from cast iron pans, sheet trays, and stacked dishes. The GR-1002 puts a buffer between that load and the sink surface. Because water flows under the grid rather than sitting trapped beneath a flat object, the bowl stays cleaner and drains faster. For anyone running dishes through the sink multiple times a day, that drainage path makes a practical difference in how the sink performs between cleanings.
Material and Construction
Stainless steel is the right match here. It tolerates standing water, doesn't stain or discolor alongside a stainless bowl, and holds its shape under the weight of heavy cookware. The rectangular form is cut to the 520 Series bowl geometry so the grid occupies the floor without gaps at the edges that would let small items slide underneath and become harder to retrieve.
The Right Sink, The Right Grid
This grid is sold as a standalone accessory for buyers who want surface protection added to an existing E520, E525, or E528 installation, or who are speccing a complete setup from the start. Cabinet shops finishing out a kitchen with a 520 Series sink, designers sourcing coordinated accessories at the spec stage, and homeowners adding protection to a sink already in service will all find this a direct, no-guesswork fit. If your sink is not one of those three models, a different GR- number will apply.
Will this grid fit any other Karran Edge models outside the 520 Series?
No. The GR-1002 is published for the E520, E525, and E528 specifically. Other Edge models have their own grid numbers matched to their bowl dimensions. Using the wrong grid risks poor fit and reduced protection.
Does this grid come with any feet or bumpers?
The source data does not confirm feet or bumpers on this grid. Review the spec block on this page for confirmed construction details, or contact customer service before ordering if that detail affects your decision.
Is the GR-1002 included when I buy a 520 Series sink?
This grid is sold separately. It does not ship with the sink by default. If you ordered a -PK1 bundle with your 520 Series sink, check the confirmed pack contents for that SKU to see whether a grid was listed.
Can I use this grid in a double-bowl sink?
The GR-1002 fits the bowl geometry of the E520, E525, and E528 as documented. If any of those models have multiple bowls, each bowl that takes a grid will need its own correctly matched grid number. Check the fits table for your specific bowl before ordering a second unit.
Protection That Matches the Sink
The GR-1002 is a direct, model-specific answer to keeping the 520 Series bowl in good shape through years of hard use, with no fit ambiguity and no adapting required.
