Access Door for spiral duct
EasyFit duct access doors are designed to provide inexpensive and trouble free access to fire and volume control dampers and associated ventilation equipment. All doors are suitable for low, medium or high-pressure applications (to 2000 pa positive) meeting the requirements of HVCA DW144 specification for air leakage. All Doby Verrolec access doors have been tested and witnessed by BSRIA – the approved testing house for the HVCA (curved doors) and Northumbria University (tabbed doors).
Our curved access doors are available in six sizes to suit diameters from 100mm to 2000mm. No rivets or screws are required and securely fixed locating bolts ensure a positive fit. Each curved access door is supplied with a self-adhesive cutting template eliminating the need for any measuring or marking out.
