Review on IEBUOBO Stainless Steel Locking Repair Exterior Accessories by William Stewart

These quick connects are exactly as described. I use four of these to hold a 100lb punching bag and they work great. The unscrewable "nut" works smoothly and I can't say anything about quality defects. This size was just what I needed to work my existing chain on a heavy bag while still offering maximum strength; The size you need will of course depend on your application.
