Install sink clips along the underside of the sink. Position them on each ridge of the sink rim. Tap them into place gently with a hammer, so you don't crack the sink. Then loosen the screw to allow the clips to be bendable during installation.

FAQs
The project is rated 'intermediate' and 8 hours. Is this accurate for a first-timer, or should I expect it to take longer?
For a first-timer, budgeting more than 8 hours is wise, as unfamiliar steps like precise sealant application, securing clips in tight spaces, and leak testing can take extra time. The 'intermediate' difficulty stems from requiring precision with sealant, proper plumbing connections, and handling a heavy sink, which all benefit from patience.
Are there any 'specialty' tools I absolutely need for an undermount sink installation that aren't common household items?
Yes, a basin wrench is crucial for tightening nuts in tight spaces behind the sink, and a high-quality caulk gun (like the Husky 10 oz.) is essential for smooth sealant application. Bar clamps (e.g., BESSEY Clutch Style) are also vital for holding the sink firmly against the countertop while the sealant cures and clips are secured, ensuring a tight, leak-proof bond.
What is the most common mistake DIYers make when installing an undermount sink, especially regarding leaks?
The most common mistake is improper sealant application or insufficient curing time, leading to leaks between the sink rim and the countertop. Ensure a continuous bead of 100% silicone sealant, press the sink firmly into place, and allow ample time for the sealant to cure before connecting plumbing and testing for leaks. Also, always use Teflon tape on threaded plumbing connections.
What are the crucial safety precautions I should take before starting this project?
Always shut off the main water supply to your kitchen or the entire house before disconnecting any plumbing. Wear appropriate eye protection throughout the process, especially when dealing with sealants or tight spaces. Ensure you have adequate support for the sink during installation to prevent it from falling, and clear your workspace to avoid tripping hazards.
