CRL Snaptoggle Toggle Anchors pre-install without a bolt and can be installed using a screw gun because the anchor won't spin in the hole. They also allow for bolt or fixture removal without the anchor falling behind the wall. Use in drywall, plaster, cement board, hollow walls of block, brick, stucco, fiberglass and wood. The grip range is 3/8" to 3-5/8" (10 to 92 mm).
