2 Rigging the Razor Harness 2
Below is an easy to follow guide detailing the 10 steps to rigging and adjust-
ing your Razor Harness.
Each step has supporting pictures.
It is highly recommended that you read through the guide and look at the
accompanying pictures to thoroughly familiarize yourself with the various
parts and assembly procedures before you start to put your Razor Harness
together.
Ideally you should have your Side-Mount Instructor rig your Razor Harness
with you.
Rigging the harness is much easier with 2 people.
No one is perfectly bilaterally symmetrical and a properly fitted harness will
not be either.
The person having the harness fitted should wear it while their partner makes
adjustments in situ to get the perfect fit.
If rigging the harness by yourself a full length mirror will help you to position
everything correctly.
Ideally when you rig the harness you should do so while wearing your normal
exposure protection so that it fits snugly. If that is not practicable then
wear clothing of a similar thickness to your normal exposure protection and
make sure you leave some extra webbing for later adjustments should they
be required.
It is highly recommended that you use the T weight system with the Razor
Harness however if you are going to put weight directly on the Razor Harness
then it is advisable to work out how much weight you will need and where you
want to place it on your harness before assembling it (see Step 9: Weighting
and Trim).
2.2 Overview

2 Rigging the Razor Harness 2
Your Razor Harness comes already partially pre-assembled to give you an idea
of how everything should fit together but you will need to make some adjust-
ments to get the best fit possible.
You may need to disassemble it to replace the standard D rings with the low
profile D rings or to add weight directly to the harness itself although it is
recommended to use the T Weight System to add any weight you may need.

The DSP is placed with the button head screw on the inside against the div-
ers back
The DSP should be
positioned between
the shoulder blades
below the nape of the
neck.
To get the right height
place 1 arm behind your
head and the tips of your
fingers should just touch the
top of the DSP.
Make sure that the top of the DSP
is clear of your Drysuit neck seal or zipper.
It should also be positioned below
the closed zip position of a wetsuit.

Making sure the DSP remains in the correct position the shoulder D Rings
should be positioned at the same approximate height as the ends of the
clavicle.
To fine tune this position stand with both arms straight out from the shoul-
ders palms facing down and thumbs extended then bend at the elbows until
the thumbs hit the shoulders without lowering the arms.
The D Rings should be placed at this height and can be moved to the ideal
location easily by sliding the serrated tri-glides either up or down the webbing
ensuring each side is even in height.

Step 2: Fitting the Chest D Rings

12
For divers using the warm water Low Profile D Ring Kit the standard 2” D
Rings should be changed for the 1” version in the LPDR Kit
The webbing will have to be unlaced from the MBP in order to do this.
Weights can be added to the Shoulder Straps where they exit the DSP and
before the shoulder D rings if required (see Step 9: Weighting and Trim)
but it is recommended to use the T Weight System rather than add weight
directly to the Razor Harness itself.
The webbing will have to be unlaced from the MBP and the shoulder D rings
removed in order to do this.

Adjustment
As the Crotch Strap end has a
sewn loop Awith a 1”low pro-
file scooter D Ring B.
It cannot be adjusted for
length from this end and
all the adjustment must
take place at the DSP C.
2 Rigging the Razor Harness 2
Step 3: Fitting the Lumbar / Crotch Strap
Position the top of the Crotch strap loop at
the correct height just below the belly button
and then pull the free end of the webbing
through slot C of the DSP until the correct
overall length is achieved making sure the
correct position of the DSP is maintained.
The Lumbar / Crotch Strap is a continuous piece of
webbing that begins at the DSP.

Adjustment
The free end of the webbing
should be doubled back through
the wide gauge Tri-glide on the
Lumbar strap to lock it in place.
2 Rigging the Razor Harness 2
Step 3: Fitting the Lumbar / Crotch Strap
If using a butt mounted primary light canister
remember to leave the crotch strap a little
loose so that it can pass over the light can-
ister to hold it in place while diving or even
better size the crotch strap with light canister
in place.
The loop of webbing created between the DSP
and the wide gauge Tri-glide should be large
enough to comfortably pass the Side-Mount
Bungee and clip through with the
bottom of the loop in line with the
armpits (see Step 8: Sizing and
Fitting the Side-Mount Bungee).

Make sure to leave plenty of extra webbing for any adjustments that may be
required later then cut off any excess and burn the end to seal it.
The free end of the webbing should be on the underside of the Lumbar Strap
towards the diver and can be held neatly in place with a loop of bicycle tire
inner tube.
Weights can be added to the Lumbar Strap below the wide gauge Tri-glide if
required (see Step 9: Weighting and Trim) but it is recommended to use the
T Weight System rather than add weight directly to the Razor Harness itself.
Step 3: Fitting the Lumbar / Crotch Strap

The position of the MBP will determine the position of the lower attachment
points for the bottom of the Side-Mount Tanks.
Most divers will position the MBP at waist height but shorter divers may wish
to move the MBP lower to mid hip height to be able to position the side
mount tanks lower on the body for greater comfort.
Step 4: Adjusting the height of the MBP

ence.

Pass each shoulder strap through the inside of slot C on the MBP then back
out through slot D.
The Harness should assume a “Heart Shape” at this point with the shoulder
straps entering on the inside of the MBP and the Waist Straps exiting on the
outside.
Tighten the shoulder straps until you have a snug fit which is even on both
sides with the DSP and MBP centered along the midline of your back and
the MBP at the desired height.

Weights can be added to the Waist Straps where they exit the MBP if
required but it is recommended to use the T Weight System rather than add
weight directly to the Razor Harness itself (see Step 9: Weighting and Trim).
All the hardware on both sides of the waist straps will have to be removed
in order to do this.

The two Drop Attachment Points (DAPs) should be positioned on the waist
webbing either side of the MBP.
The DAP’s should be close to the MBP so that anything clipped to them will
not hang too far to the sides and get between the body and the SM tanks.
If required the loop of the DAP can be placed in a vice and bent gently to
have them stand off slightly from the body to make clipping in easier.
The DAPs are an ideal location to clip off the Razor Expandable Pouch as
well as other items such as reels or lift bags for example.
The DAPs can also be used to clip off a heavy butt mounted primary light
canister to give it more support if required.
