More Information on the VXR4000 Recessed Flush Fit Trickle Vent
Manufactured by Titon this recessed 4000 trickle vent is used widely on timber windows where the frame has been routed to a slot and where the trickle vent can sit flush to the frame!
Normal surface mounted trickle vents can't be used where recessed trickle vents are needed as they won't open correctly. The VXR4000 trickle vent has a different motion that allows it to move forward and away from the frame making it suitable for these applications. Take care to ensure the size is correct for the outer dimension as there have been several sizes used although the 4000 type is the most common trickle vents size for this type of application.
EA Rating: 4600. This is the amount of actual air passage using the combination of the vent, slot sizes and external canopy. This air vent is available in a 351mm length and 335mm fixing centres. Suits a recessed slot of 21mm width.
