Easy to install. They have video instruction on their website. Use a compact impact driver and you can install it in 5 minutes or less. Brilliant design. The screw is about right length, not exact the same as in picture, but it is better. The builder of my house use a wood stick at an angle to support the sink, and they put one 2" screw at the bottom of the stick to hold it, they did that on 3 sides. The long Cinclips has the right length, just long enough so the base part is just below the sink. Highly recommended.

I had a double sink with a granite counter top - installed 8 years ago - all of a sudden the first sink fell in while the house was on the market - panic....... No one would come to repair it - plumbers not interested - contactors not interested.... finally a neighbor said he would give it a try after I ordered Cinclips® - now the second one has fallen in - neighbor said he would do the second one because it was simple and really guaranteed the installation.. thanks for a good product - I can't understand that in 6 months you are on the second page of google with my search - you should be at the top - thanks for an answer to a very difficult problem. I asked a major remodeler and he said it was too much work for the money - Cinclips® makes it a do it yourself project!!!!!
