Types of Sink Clips

There are three varieties of sink clips. They come in handy in undermount, rimless, and counter-over sinks. There are no clips for the self-rimming sinks as they get sealed using plumber tape or caulk.  

The three kinds of sink clips hold the sink in place from below the counter. When choosing a suitable sink clip, you check your sink and countertop type. They include the following;

Type 1: Undermount Sink Clips

The clips come designed to use on undermount sinks. To install them, you fasten them below the counter in a cut T-slot. Then you put a bolt and tighten them using a wingnuts.

Type 2: Rimless Sink Clips

These sink clips are exclusively for rimless sinks. Like the undermount sink clips, you fix them beneath the countertop. They help pull the sink and countertop together.

Type 3: Overmount Sink Clips

They get designed for the counter-over sinks. Because the sink sits directly on the countertop, the clips get attached to the sink. With the above information, you can buy the best and suitable undermount sink clips for your sink. But you may not know how to install them. To enlighten you, below is a step-by-step guide on how to secure your undermount kitchen sink.

How to Secure an Undermount Kitchen Sink Using Clips

The securing method depends on installing the sink on a new countertop or an existing one. Whichever the case, follow the steps;

Step 1: Place the Countertop Upside Down

First, ensure the sink cut-out gets appropriately done on the new countertop. Then turn the counter up-side-down on the area you’ll fix it.

If dealing with an existing countertop, go straight to step 2.

Step 2: Apply Silicone on the Sink’s Rim

Your undermount sink has rims. Apply the best silicone caulk around them. Ensure you squeeze out enough glue on the edges. Wipeout any excess caulk with a clean rag.

Step 3: Place the Sink in Its Position on the Countertop and Secure It

After applying silicone to the rims, turn over the sink and fit it correctly on the sink-cut-out. Then identify one sinkhole and insert a self-tapping screw. Tighten it halfway using a screwdriver.

Repeat the same for all other sinkholes. Because sinkholes can vary in size and numbers, it’s essential you know the kind and number of screws to use. The sink’s manual may guide you.

You will have to lay down underneath the countertop in an already installed countertop and face the sink-cut-out area. Then take your undermount sink and insert it into the cut-out from below.

You can request someone to check for you from above if the sink has centered well on the countertop.

After setting the sink to its position, secure it from below using a piece of wood since the caulk on the rims is not yet dry to secure it.

Then place some bolt posts below the countertop where the sink rims rest and secure them with Epoxy. Allow the glue to dry. It should take at least 10 minutes.

The bolt posts positioning and the number could vary from one undermount sink to another. Check out with the manufacturer for the specifics.

Step 4: Tighten the Screws Progressively

After putting screws in all sinkholes:

  • Start tightening them little by little.
  • When you tighten the screw slightly, move on to the other screw facing it diagonally.
  • Continue with this diagonal approach until you fully tighten all the screws.

You will have to install a sink clip or holder hardware on one bolt post for the existing countertop. Then fasten it with a wingnut. Before tightening the wingnut, ensure you place a washer for better results.

Also, the holder should press against the undermount sink’s rim. Don’t fully tighten the wingnut.

When you finish, do the same with the remaining bolt posts. Then use the diagonal approach to tighten all the wingnuts fully.

Step 5: Final Step

For the new countertop, you can now turn the countertop attached to the sink over.

Check out any fault in the connection and fix it. Then clean out any dirt or excess silicone using a rag. That’s it! Your undermount sink is fully secured. 

Granite countertops are trending in most homes because of their aesthetic appeal, durability, and easy maintenance.

Some people think that securing sinks on granite surfaces may be challenging. The following easy-to-understand guide will prove that the procedure is a piece of cake.

How to Mount Undermount Sink Clips on Granite

Step 1: Mark Out the Sink Outline on the Granite Countertop

The first thing to do is mark out the sink’s rims on the granite countertop. Take your sink and place it on its cut-out on the countertop. Then drew it out with a clear marker.

Step 2: Mark Out the Position of the Sink Clip Holes

After outlining the sink, keep it aside in a safe place. Then mark out the locations of the clip holes. The marked-out sink outline will direct you on where to drill the clip holes.

It could be near the marked sink line or inches away. It depends on the space on your granite countertop.

Step 3: Drill Out the Sink Clip Holes

Use a reliable drill like the 3/8 bit to drill the holes. Ensure it’s wet to keep the granite cool during drilling. The heat generated from the procedure may damage the granite.

Also, you must drill in a circular motion for the glue to secure appropriately. You’ll also not see any dust after the drilling.

Afterward, clean and dry the holes

Step 4: Place Sink Clip Anchors into the Holes

The anchors will help hold the sink clips tightly. Begin by putting a reliable glue like Epoxy into the holes. A knife blade paste mixed with a hardener also works out great. Then insert the anchors.

Wipe out the excess glue before installing the sink clips.

Step 5: Fix the Sink Clips

Sink clips come as a package of screws, holders, and wingnuts. Place the holder into position on the clip hole. Ensure it holds the sink securely before placing the screw.

Then insert the screw into the anchor in the hole and place a wingnut. Tighten the wingnut firmly. Fix the sink clips in all the gaps.

When all clips get firmly installed, you have completed the process successfully.
