The Unique Way the ALLIGATOR anchor works
The ALLIGATOR anchor has several features that dramatically increase its
holding strength in solid and thick walls as compared to other solid-wall
anchors. The anchor has a circular cross-section and is completely solid.
This circular cross-section causes all forces exerted by a screw threaded
into the ALLIGATOR anchor to be fully transmitted around the anchor
to the wall of the hole (360° and along its full length) for full compressive
holding over the entire length of the screw.

Many other solid-wall anchors transmit compressive forces only to the thickest portion of the
anchor and unevenly against the wall of the hole. They are hollow virtually their entire length
and have many ridges, lumps, or bumps on their outer surfaces allowing for extreme pressure
differences along the anchor. Virtually all heavy-duty metal anchors utilize an expanding
wedge that presses against only a small portion of the anchor. This force is then exerted
against a short ring-shaped interval of the hole and is often so concentrated that it fractures
the substrate, resulting in catastrophic failure. The wedge element is forced against the split
sleeve by the action of the screw, but again the force is actually exerted against the substrate
only where the circumference of the wedge is at its greatest.
Old-fashioned metal wedge-type anchors, when tightened,
frequently damage and tear out portions of solid walls,
making the hole unsuitable for re-use (a). The ALLIGATOR
anchor does not damage walls when loosened or removed.
As a result, the same hole can be reused for use with
another ALLIGATOR anchor of the same size.
In additon, metal anchors that
operate with a wedging action
must be spaced far apart to
avoid overlapping “cones of
force” (b) and the consequential
weakening of the wall.
Because ALLIGATOR anchors, with
their unique technology, do not
concentrate their holding in a small
area, they can be more closely spaced
(c) for greater maximum total load on
the smallest substrate surface area.
Old-fashioned plastic plug anchors are usually made of a relatively hard plastic such as nylon or
polyvinyl chloride (PVC), which does not readily conform & flow into the surface imperfections of
the wall of the hole. Accordingly, there is no bonding of the anchor to the walls of the hole. The
ALLIGATOR anchor is made of a specially formulated grade of polypropylene. The screw
extrudes & molds the anchor into all the wall’s imperfections, providing an additional locking bond
of the anchor to the wall. Following removal of the screw, nylon and other hard plastic anchors
slide right out of the insertion hole. The ALLIGATOR anchor, however, remains molded to the
wall. A significant force is required for its removal, an additonal factor in its holding strength.
Because of the solid form of the ALLIGATOR anchor, the screw extrudes and compresses
all the plastic into the screw threads and outwardly against and into the wall of the hole.
Under tremendous pressure, the plastic of the anchor flows to form a solid cylinder that is
molded and confirmed exactly to the surface of the hole and the screw for the most
complete compression holding possible. Furthermore, the ALLIGATOR anchor flows into
and locks up with any undercuts in the hole. With this fully conformed cylinder of plastic,
the ALLIGATOR anchor provides a high degree of safety with high residual holding power
even if the anchor is partially withdrawn.
