Many of our Canadian customers saw a number of changes to the DuraPlus HTC product line at the HPBA Show in Atlanta this past Spring. We are now ready to introduce these items for sale into Canada. We have listened to our customers and installers over the past couple years as to how to make DuraPlus HTC better and easier to install. We think you will be glad to see these additions and changes. These products are now available for purchase and are in our online catalog and excel price sheets. If you have any questions regarding these items please contact our Canadian Regional Managers Geoff Wilcox (eastern Canada) and Dalton Hooker (western Canada). Information is also available through our Website (www.duravent.com), Customer Service Department and Tech Services Department (800-835-4429).
