Alternative Solutions

Disassembled – Do Not Remove Enter the name of the object being torn down

and a picture of the completely disassembled

product.

• The TackSert® pins can

replace a threaded hole and

screw, thus eliminating the

need for loose hardware, while

providing a permanent

solution. It can be installed

with a simple pressing action

instead of a more complicated

turning action.

• The TackSert also eliminates

the need for a pressed in

insert.
