Cobra Anchors 753S Wall Anchor, 2-1/4 in L, Nylon, 85 lb

The WallGripper® is the only expandable screw-in anchor on the market. It expands and grips behind the drywall and it is twice as strong as a regular screw-in anchor. Its patented design offers the ultimate holding power without any pre-drilling. Its unique body design consists of four expandable wings that collapse and grip tightly behind the drywall. A fine centered point helps guide the anchor into the wall with flawless precision. A sharp cutting edge reduces the force required to cut the material. Also, a sharp profile thread cuts deeply into the hole to ensure ultimate holding power and stability without damaging the wall material.
