Made this adapter for my Festool TKS 80 EBS Table saw. The adapter allows the 57,2mm diameter of table saw hose to be connected to a 120mm hose. I have it connected to a Felder AF14 dust extractor and it works quite well.
The two hooks on each side are meant for a rubber band or string to keep the adapter firmly attached to the vacuum hose.
