The Jackson 20-330 Series Overhead Concealed Closer has been the leader in the industry for more than 35 years.  The closer is manufactured in the U.S.A. under strict ISO 9001 guidelines and is designed to give long lasting, maitenance-free performance.  One basic closer mechanism allows for single or double acting, center-hung, or offset applications and is non-handed.  The adjustable spring power makes this closer suitable for aluminum, wood or steel doors.
