Stainless Steel Sink Grid Fits for QT-721 QU-721 Left Bowl

Bowl-Matched Protection for the QT-721 and QU-721 Left Basin

The Karran GR-6018 is a stainless steel bottom grid engineered to fit the left bowl of the QT-721 top mount and QU-721 undermount sinks. It sits on the bowl floor to elevate dishes, cookware, and produce off the basin surface, letting water drain freely beneath while reducing contact wear on the sink material.

Key Features

• Precision fit for the left bowl of the Karran QT-721 and QU-721 sinks, sized exactly to those basins.
• Stainless steel construction holds up under daily kitchen use without corroding or bending out of shape.
• Raised grid design keeps dishes and cookware elevated so water drains beneath rather than pooling under them.
• Surface protection reduces direct contact between utensils, pots, and the sink bowl, helping maintain the sink's finish over time.
• Low-profile form stays inside the bowl without interfering with the faucet, sprayer, or items loaded over the rim.

Putting the Left Bowl to Work

The left bowl of a QT-721 or QU-721 typically takes the larger share of prep and wash tasks — soaking sheet pans, holding a colander of rinsed vegetables, or staging dishes before they go into the dishwasher. A well-fitted grid keeps all of that activity from grinding against the bowl floor. Because the GR-6018 is sized to the left basin specifically, it seats flush against the walls and sits level, so items rest stably rather than tipping at the edges.

This matters most in kitchens that see heavy daily use: a grid that shifts or overhangs is a nuisance; one cut to the exact bowl footprint stays put. If you're working from the left side of the sink for most prep, this grid quietly does its job without drawing attention to itself.

Stainless Construction Built to Last in the Bowl

Stainless steel suits the sink environment well. It resists the moisture, soap, and food acids a bottom grid faces every day, and it cleans easily without special products. The grid's wire construction allows full water drainage, so standing water doesn't collect on the rack between uses. The open frame also makes rinsing the grid itself straightforward when it needs a quick clean.

Because the GR-6018 stays inside a sink that already takes the brunt of kitchen use, a durable material choice matters more here than almost anywhere else in the kitchen. Stainless holds its form and appearance across years of use without the warping or discoloration that lower-grade materials can show.

The Right Accessory for QT-721 and QU-721 Owners

This grid is the right call for anyone who has already invested in a QT-721 top mount or QU-721 undermount quartz composite sink and wants to protect that investment from day-to-day wear. Cabinet shops specifying complete sink packages, kitchen designers selecting accessories alongside a new sink installation, and homeowners outfitting a renovation all benefit from getting the bowl-matched accessory rather than a generic rack that fits loosely or not at all.

It fits the left bowl only. The right bowl of the QT-721 or QU-721, if applicable to the model configuration, takes a separate grid sized for that basin. Picking the correct bowl-specific grid prevents the common frustration of a rack that doesn't seat correctly or leaves the bowl edges unprotected.
