I should have looked at the pictures better. There is a simple rubber corner plug. This is not a soft close. Sift Close is a spring-loaded mechanism that helps gently pull the drawer out the last few inches. You have to press hard on it and it's hard to open. Very disappointed that no installation instructions or distance information were included. They are much thicker than standard rails. So when replacing existing ones, you need to open a cabinet or craft a drawer. narrower price is good for non-soft close
