How Does it Work

Second layer
fits loosely on
top of dowel

Dowels
fit tightly
in first
layer of
BlocX

Dowel and wedge
are fitted into
second layer

Hollow punch
protects
dowel top

Wedge
fits into
dowel

When driven home
the wedge expands
and locks up the
dowel below

BlocX are linked together using the WoodBlocX Principle...
