4" CONNECTOR D4262

Finally found a standard connector that actually fits snugly without wiggling loose during use. The 4-inch size is exactly what I needed for my setup, and it feels solid right out of the box.

Couldn't ask for a smoother fit—the 4-inch diameter lined up perfectly with the connection point, and the standard option feels solid in hand. I've used it for a few jobs now and it holds up without loosening, so I'm grabbing another one.

Exactly the right size for my ductwork connection, and the 4-inch fit into my existing setup without any extra adapters. The standard option was sturdy enough to hold everything securely in place.
