ZoningSupply is now offering the BEST quality Spring-Open damper available.  If you have had any experience with SPRING type dampers you already know that they have been known to have a lower reliability than SUPER-DUTY power dampers.  However, the Spring dampers that we are offering have been designed with precision and heavy-duty parts.... they are NOT the typical low-cost damper available from other companies.  If you are not sure that this is the best spring-damper you have every used, send it back and we will refund your purchase price.
