In hollow walls (drywall, tile over drywall, hollow block, hollow
brick, etc.), as the screw enters the hollow space, it opens
the jaws of the ALLIGATOR anchor. The screw thread locks
into the teeth of the anchor to resist vibration and shock.

• Holding strength for an ALLIGATOR solid-wall anchor varies directly with the strength and condition of the substrate, the screw size,
and the extent of the screw engagement—and inversely with variations in hole diameter and the distance of the load from the wall.
• All figures in pounds. Pull-out values based on independent laboratory tests done according to U.S. Government standards. They
should be used as guides only and cannot be guaranteed. The age, condition, and capacity of the substrate must be considered.
• Industry standards recommend 1/4 of ultimate test load.
The latest generation of the ever-evolving
TOGGLER solid-wall anchor technology...
• Strongest—holds up to
2x more
than metal, adhesive,
epoxy and chemical anchors with the same screw diam-
eter and embedment depth
• Anchor
bonds
screw to concrete, brick & stone—
sealing the hole against moisture
• Versatile—holds securely even in hollow walls / ceilings
• Uniquely shaped head prevents spinning & countersink
• Accepts greatest range of screw sizes in each anchor
• High holding strength even with deviations in screw size
and hole diameter, where other anchors fail entirely
• Resists vibration & shock • Non-toxic • Sets instantly
• Screw can be removed and reinserted in same anchor
without loss of holding power
• Corrosion-proof when used with stainless steel screws
ALLIGATOR anchors are designed to hold high
loads in solid walls, ceilings, and floors ... but also
hold securely when they encounter an unexpected
cavity, such as in hollow brick or hollow block, or
even in drywall or, especially, in tile over drywall.
The specially formulated polypropylene body flows
into and locks up with any undercuts in the hole,
bonding the screw to the wall and sealing the hole
to prevent moisture from entering.
Optimal holding values [measured in tons] are
obtained in highly dense substrates by using a
screw diameter and a drill diameter of the same
size as the anchor diameter.
The anchor is available both unflanged for push-
through mounting and with a flange for use where
a cavity is anticipated (drywall, hollow brick, etc.).

Benefits:
In solid walls (concrete,
masonry, brick, etc.) the
ALLIGATOR anchor extrudes
up to 2x its original length
& bonds the screw to wall
Before anchor is
inserted into wall
As screw is inserted,
anchor bonds screw to wall
