Set of 4 : 1/2" to 5/8" break-over load binders. These binders have never been used just tucked away in the corner of the garage. My price is firm as these sell for $150 - $175 each depending on where you buy them new. Here are the load specs for these binders: WLL : 13,000 lbs Proof Load : 26,000 lbs Ultimate Load : 46,000 lbs
