3. Features:  Anchor piece tooth’s shape is reasonable,damage the surface of anchor lightly ,seize the rope firmly.anchor piece has 3 disc,and it is bevel,the direction of turning is opposite to the steel strand,so it can allot the tensile force which from the steel strand well ,the anchor piece can follow up efficient. High coefficient of efficiency ,support safely and reliably. 4.Packaging: Kraft paper carton packing,Contains 25 sets of anchorage,Each anchorage packaged by plastic bags independently.       Company Strength Qiaolishen is the first company to produce, research and develop mining prestressing force series products of professional manufacture in domestic.
