Help With a Cobra Anchor WallGripper That Won't Go In

Help With a Cobra Anchor WallGripper That Won't Go In thumbnail
Drilling a tiny starter hole can help you drive your WallGripper.

Cobra Anchors' WallGripper product includes a distinct strengthening feature that's unfamiliar, and occasionally problematic, to most do-it-yourself builders. Unlike a conventional thread-body wall anchor, the WallGripper's shank expands after penetrating the wall, similar to a toggle or "molly" bolt. While this feature increases the anchor's holding strength compared with a standard design, it also adds a new layer of difficulty to the installation procedure. If your anchor won't go in the wall, there's still a chance that you can salvage the anchor. Learn about the recommended WallGripper anchoring procedure and potential installation challenges to find out how to complete your project.

  1. Recommended Tools and Materials

    • If you're having trouble making your WallGripper penetrate the wall, you might be using the wrong tools or applying the anchor to unsuitable wall covering materials. Cobra Anchors explicitly suggests using a screwdriver to drive their WallGripper product. Using a power drill might strip the WallGripper's slot, which will prevent the anchor from threading into the wall covering. Also, Cobra Anchors specifies that the WallGripper is suitable for 1/2 and 3/8 drywall. The WallGripper is a plastic product and, although its tip is sharp, it can't penetrate wood paneling or lath and plaster walls.

    Suggested Installation

    • Reviewing the suggested installation process can help you penetrate the wall with a WallGripper. Installation breaks down to a simple three-step process: pierce the drywall with the anchor's tip, drive the anchor with a screwdriver until the anchor's head is flush with the wall and drive a screw into the anchor's center slot. Driving the screw through the slot should expand the Wallgripper's hollow body, causing the anchor to grip the wall's interior face.

    Penetration Problems

    • If you're sure that you're driving the WallGripper into an acceptable wall covering material and you still can't penetrate the wall, you can create a small pilot hole to help you get started. Use a nail or drill bit that's no more than half the diameter of the WallGripper's shank. Pierce the wall with the nail or drill bill to create a tiny hole. Use the hole to hold the tip of the WallGripper in position and guide the anchor as it drives through the wall.

    Damaged Anchors

    • The perforated shank of the WallGripper isn't supposed to expand until it's within the wall's cavity. Damage during shipping or from repeated installation attempts might prematurely spread the anchor's gripping tabs. If your WallGripper's shank is spread wider at its center than at its top or bottom, the anchor won't penetrate the wall. You can try to salvage the anchor by pressing its tabs flush with its shank. If the tabs spring outward or remain loose, you should abandon the damaged anchor and attempt the installation with a fresh one.
