Plastic toggle anchors provide vibration-proof anchoring of light to medium loads in hollow walls & ceilings but also hold securely when they encounter an unexpected solid, such as a wooden stud, or when performing as wedge anchors in materials with thicknesses above their normal wall grip range. Improvements in the original design have increased holding strength and abuse resistance. Holding arms have been thickened and strengthened without increasing the insertion hole size, and major stress points have been significantly reinforced without increasing anchor size.
