The GBS/RBS Bend short has a 90° bend right after the spigot. This type of bend can be used for rectangular ducts that are installed snugly to the wall with a direct angle straight through the wall, for example.
In terms of airflow, this bend provides more resistance than a GB bend. This fitting has a KEN-LOK rubber seal with double lip (Soft-Edge) at the end of each spigot, so it can slide easily into a Spiralo duct.
