Frequently Asked Questions
What is the Heavy Duty L-shape sink clip used for?
The Heavy Duty L-shape clip holds deep bowl, oversized, and other heavy undermount sinks to the underside of a countertop. Sink clips, sink brackets, and undermount sink brackets all describe the same part.
Do Heavy Duty sink clips work with Keep-Nut and glue-on anchors?
Yes. They work with both Specialinsert Keep-Nut anchors and Chem-Set glue-on sink anchors. Call (800) 220-1966 to match the clip to your anchor thread.
How much weight can a Heavy Duty sink clip hold?
We do not publish a load rating for this clip. Holding strength depends on the anchor, the adhesive, and the countertop material, so call (800) 220-1966 before installing a very heavy sink.
How many Heavy Duty clips come in a box, and can I order more?
Each box holds 100 clips. Call (800) 220-1966 for quantities above one box.
When should I use a different clip than the Heavy Duty?
Use the Z-shape for standard installs, the C-shape for compact sinks, and the Short Rise or High Rise L-shape for bowls with a higher rim. All five styles are on the metal undermount sink clips page.
