1. Simply Repair an Undermount Sink: The probability of the sink falling after about 2 to 3 years of use is 99%, and our product can prevent your sink from falling. Enjoy your cooking with this sink support, which is suitable for wash basin and kitchen single/double bowl sink. 2. Adjustable Support: Our sink support can be telescopic in height. As long as the height of the bottom of your sink from the ground or cabinet bottom is from 15.7 to 39.4 inches, you can choose our supports. (Please choose the appropriate support size based on the measured height from the bottom of the sink to the floor or cabinet bottom.) 3. Firm and Won't Fall Off: The thickened removable base is designed with a non-slip rubber bottom pad, which is wear-resistant and firm, ensuring a better fit between the base and the surface. It can effectively lock the bottom of the sink to prevent movement or slipping off and protect the bottom of the sink from wear and tear. 4. No Rust: The undermount sink supports are made of stainless steel, which has the advantages of high hardness, rust-proof, and corrosion resistance. So, the sink supports can be used for a long time in humid environments such as bathrooms, toilets, and kitchens.
