Product Description

Bell Mouth Spigot, Round Constant Air Damper

Raw material: Galvalized steel sheet
Size: Combining with the air duct size
The recommended method of fixing the spigot to ductwork or the like is by the use of blind steel rivets with a grip capacity of 4.8mm, or by spot-welding if suitable equipment is available.
In either fixing method, the spacing of the rivets or spot-welds is not considered critical as the bottom of the flange of the spigot is very rigid - as a general guide, however, a maximum spacing of 110mm measured around the flange diameter is suggested.
Rivets and spot welds should be placed approximately 5mm from the outer edge of the flange.
