Deflecto DIRB65 is an aluminium increaser and reducer that steps between the two sizes, so it works in either direction. It's handy when a rangehood spigot and the existing duct don't match, or when you're upgrading a run to a larger diameter. As a universal fitting there's no model list to check, just confirm the sizes of the spigot and duct you're joining.\u003c\/p\u003e\n\u003ch2\u003eMatching rangehood and duct sizes\u003c\/h2\u003e\n\u003cp\u003eRangehoods and exhaust fans move air best when the duct is the right size and the joints are smooth and sealed. Many hoods have a 150mm outlet while older ceilings or walls may already have 125mm duct, or the reverse. Forcing a mismatched duct on leaves gaps that leak greasy air into the ceiling space, and squashing it narrows the airflow. A proper increaser reducer makes a tidy transition. Keep in mind that stepping down to a smaller duct can reduce the hood's extraction and raise the noise, so check your hood's recommended duct size.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDeflecto part DIRB65\u003c\/li\u003e\n\u003cli\u003eSteps between 125mm and 150mm duct\u003c\/li\u003e\n\u003cli\u003eAluminium construction\u003c\/li\u003e\n\u003cli\u003eWorks as an increaser or a reducer\u003c\/li\u003e\n\u003cli\u003eUniversal fitting for rangehood and exhaust ducting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e125mm to 150mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eInstalling the increaser reducer\u003c\/h2\u003e\n\u003cp\u003eTurn the rangehood or fan off at the wall before working on the ducting. Push each end over or into the matching duct or spigot, then secure every joint with duct clamps or screws and seal it with aluminium foil tape so grease and moisture can't escape. Keep the run as short and straight as possible. Any new wiring for a rangehood must be done by a licensed electrician.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eWhich way round does it go?\u003c\/h3\u003e\u003cp\u003eEither way.
