Troubleshooting ceiling fan mounting on sloped ceiling remote won't fit. Look like I need an elongated mounting part. Just bought harbor breeze fan at Lowe's. What can I do to make the wireless remote slide into the unit. The sloped ceiling is making it difficult to slide the remote in place .

Place the remote into the housing first, then mount the housing, if possible.

It is difficult but it will fit. Try Don's suggestion, much easier on your neck and back.
