About this item
- EXCELLENT QUALITY The neverest RK 5" ducting connector with backdraft shutter is very robust and durable. The housing is made of galvanized steel and the damper blades are made of aluminum. Two stainless steel springs are for automatic closing while the rubber ring ensures 100% closure and quiet closing.
- PRODUCT FUNCTION The backflow damper blocks the cold and warm air from entering through the ventilation duct. The flaps open when the extractor fan blows out the exhaust air and automatically close as soon as the airflow stops. The flaps must be aligned horizontally in order to close optimally.
- MULTIPLE USE This backdraft damper can also be used in whole-house ventilation, passive ventilation, air conditioning hose connector, vent connector, HVAC and Heat Recovery Systems. Fits all common round ventilation pipes and 125mm flexible ducting according to DIN EN 1506.
- PERFECT CHOICE Designed for long-lasting ventilation systems ideal for home improvement. Can be used to join multiple lengths of pipe together to form a long duct run or connect directly to a ventilator.
- NOTE This is to be installed in metal ducts only. Measure the diameter of your duct before purchasing. We are experts in ventilation for more than 40 years. If you have any questions or complaints, please contact our customer service directly. Your request will be processed immediately.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
