Assembling 1/2 x 1 inch wire mesh. The pliers are too big to fit properly in the holes. I pushed my head down a bit and it helped a bit. Maybe the gauge I'm using is too thin because the pliers aren't tightening the clamps tight. Inserting the J-clamps into the pliers is awkward. I've never used these clamps and pliers, so maybe I'm missing something. But the experience was terrible. I thought it would make assembly easier, but it isn't.
