Description
Sinkits High Rise is an undercounter sink mounting clamp for thick rimmed sinks in granite, quartz, concrete, and other hard countertop materials. It is built for sink rims up to 1 3/8 in, giving fabrication crews a mechanical mounting path without loose clips, screws, nuts, washers, or epoxy cure time.
Sinkits High Rise Benefits
- Tall body height supports thick porcelain and similar sink rims up to 1 3/8 in.
- Mechanical insert style lets crews drill, place the clamp, and move on without waiting for epoxy.
- Integrated clamp design reduces small loose hardware at the installation bench.
- Shop-drilled holes can help crews prepare tops before field installation.
- Compact body works in tight sink cutout areas where access is limited.
This version fits countertop teams that see thicker rimmed sinks and want a repeatable installation method. Confirm rim thickness, deck material, and available underside clearance before drilling.
Sinkits High Rise Applications
- Thick porcelain sink rim installations under stone tops.
- Granite, quartz, marble, concrete, and solid hard surface countertop work.
- Fabrication shops preparing sink openings before delivery.
- Field service calls replacing missing or failed sink support hardware.
- Countertop crews standardizing clamp inventory for varied sink rim heights.
Installation Notes
Mark clamp locations based on the sink, rim thickness, and countertop material. Drill clean holes to the required depth, clear dust from the hole, and test fit the clamp before final sink placement.
Do not assume every top or sink rim needs the same clamp spacing. The installer remains responsible for clamp count, placement, substrate condition, and the support needed for the actual sink.
Technical Details and Documentation
Sinkits documentation lists four clamp variations for different rim heights, with the High Rise version covering sink rims up to 1 3/8 in. For fastener category context, review the Industrial Fasteners Institute when setting internal hardware standards.
