Do the doors require additional clearance on the sides, or do the hinges function so that it will work within a 42” opening with walls on both sides?

The hinges on the Aveley cabinet seen here allow for the doors to open to approximately 105 degrees. Enclosing the cabinet in a space that is 42” will limit the overall opening angle, but they should still be able to open. We encourage you to reach out to a Specialist in the Kitchen and Bath department at your closest Lowe’s to go over your design ideas. We appreciate your interest in allen + roth, and we hope you’re able to find the perfect cabinet for your space!
