Review on 🔧 Supply Giant 6I49 Black PVC Coupling, 4 inch, with Stainless Steel Clamps - Flexible and Durable by Antonio Fox

TOO BIG FOR A 4" PLASTIC WOODWORKING DUST COLLECTOR. I ordered this 4" coupler to replace my standard 4" 90° port dust collection port with a 4" star on my dust stop over the handheld dust outlet, the description says it's for 4" cast iron, plastic, or steel pipe and the coupling size is 4" × 4" × 6". After receiving the part, the clamps will show 4 1/8"-5". The ACTUAL outside diameter measures 5 inches in diameter and 4 inches in height. ACTUAL inside diameter is 4 1/2 inches. My 4" dust collector has an OD of 3 15/16", so this 4" coupler is about 5/8" larger. I will be returning for a refund and taking my sprocket to the home depot to pick up the clutch as I should have done at the 1st location.
