4" X 2.5" QUICK COUPLER D4231

The locking mechanism engages with a solid click that gives me confidence it's not going to pop loose under heavy use. Even with the abrasive dust in my shop, it connects and disconnects smoothly without binding up.

The threads cut clean and mate without any wobble, so the connection feels solid even under a steady abrasive load. Swapping attachments took me under a minute, and the locking action is reassuringly positive.

The fit on my D4231 is snug right out of the box, and the steel feels solid enough for daily use on our abrasive line. Saves me a good few minutes during changeovers compared to threading standard fittings.
