Our 30" sonnet chimes have 5 heavy walled, center pinned tubes that emit deep tones. All aluminum construction, durable powder coated and anodized finish, and strung with industrial cord. Each chime has an adjustable striker. Tubes are 7/8" diameter, sentiment is printed directly onto the tubes. Each Chime Tube Reads: Lord, bless our door that opens wide to welcome those who step inside. Bless our home dear Lord above, that we may share Thy joy and love.
