Review on Woodstock D4231 2 Inch Quick Coupler by Corey Krull

I had trouble finding adapters that actually fit my tools and shop vacuum. Almost every 4" socket I've tried is the same diameter as the dust port on my tools, meaning it won't fit into the dust port and won't make a connection. This connector has a 4" ID and actually fits in the dust bag of my band saw and planer. The 2 1/2 inch side also fits my shop vacuum well and hasn't given me any problems falling off during use. Many thanks to Woodstock for making an adapter that actually fits and works.
