How Adjusta-Flex Works 

The first thing we
realized was that
a hose donut does
not have to have a fully connected perimeter to
do the job of protecting
the hose and fittings

The donut is able to
flex up and down, in
and out. In doing so,
the inside is able to
hold a true circle thru
 a range of different diameters.  The flex
and open areas
make it work

for placement
over or around 
hose or fittings


The 3 areas that are cut away, create the "Flex Points" that are the
key to the design.  We
call these "Bridges."
They allow the donut to
move in every direction

By removing a section
from one area of the donut, we are able to reduce and enlarge its diameter as needed.
The "Flex Points"
allow it to hold
its true circle


The Adjusta-Flex Donut shown in the
photos below
is the  "same donut"  .

It is extremely versatile.  Below you can see that it fits tight around
three different hoses.  Each hose has a different outside diameter of 2.40"
2.50" and 2.79".   The full range is approximately 2.38" to 2.9" for our #220-2"
Hose Donut.  We offer ranges to cover OD dimension of .1.24" all the way to 7.4". 

Many Inspectors our now requiring hoses to be off the floor
Adjusta-Flex #200 and #1000 Series are very reliable,
consistently tight on the hose and easily do the job
