This is a good heavy insert for a Gooseneck Bulldog pendant. Watch out though, because the bulldog has made both a square and a round bet. Unfortunately I didn't pay enough attention when ordering and got a sturdy square insert, but I needed a 25K cartridge. The store I ordered it from doesn't work for me and the shipping costs more than the purchase price. In terms of quality, the welds on this insert were very good with a very robust overall configuration. Again, be aware of the square and round mortise requirements.
