Although the TOGGLER ALLIGATOR® plug may look like ordinary plastic plugs, they function very differently to hold more weight than most concrete and masonry anchors made out of metal. Thanks to the Alligator® plugs unique, patented design, they can even hold more than most chemical, epoxy, and adhesive anchors.
In unexpected cavities (like hollow brick or hollow block) and in hollow walls (like tile over drywall or in drywall itself), the screw opens theĀ Alligator® plug and locks its thread into the anchorās teeth to resist pull-out and vibration. In a solid substrate like brick, concrete or evenĀ lightweight blockĀ theĀ Alligator® plug extrudes itself (rather than expands) along the length of the screw which gives even holding pressure along the length of the fixing rather than just at the point of expansion like in most other āplugā type fixings.

Now thatās no ordinary plastic wall plug.
