I am very pleased with the general quality of these fittings however, I’ve had to grind down the metal ‘tag’, on the side where the cupboard door hangs,(the tag that catches the soft close mechanism) as it caught the edge of the door. I have used these in good quality 400mm cupboards but whilst there is plenty of adjustment to make the fittings fit slightly wider, there is no adjustment the other way. They are a very tight fit and thus the need to grind down the door side tag. Over all I feel happy with my purchase but wish I hadn’t had to make any modifications.
