USER MANUAL

1
The CXUL.XL is an Ultralight BASE harness/container system with integrated risers. It is imperative
that you take the time to learn the proper assembly, packing, and closing procedures before you
use this system. If you are unsure of any aspect of the assembly or use of this system, stop use
immediately and seek professional instruction. We recommend that you assemble and pack this
container system under the guidance/instruction of a qualified BASE instructor or parachute rigger.
THE SYSTEM
Common techniques used to pack other 2-pin container systems, which use a floor-plate closing
method for the top pin, will work for the CXUL.XL as well. Please keep these points in mind:
1. We recommend placing your pull-up cord through the top closing loop before placing your canopy in the
container (easier to access once the parachute is covering the loop).
2. You can place the tailpocket in the packing tray regular or inverse, high or low. However, the placement
shown here has proven to work well with this container.
PACKING TIPS
Your CXUL.XL is shipped with two sets of
closing loops. Install the shorter closing loop
into the bottom flap of your container, and the
top (longer) loop into the floor-plate inside the
container. Use the washers provided – they
must be placed between the grommet and the
knot. Note that the closing loops supplied with
your CXUL.XL are double-ended, and can be
reversed when one side begins to show wear.
CLOSING LOOPS
The CXUL.XL’s chest strap is made from 3000 lb. nylon webbing, and the non-
slip milled aluminum buckle is rated to over 14 kN. As a single component,
the chest strap is more than strong enough to support bodyweight. NEVER
rappel from your chest strap without the proper hardware, instruction, and
experience, and always back-up all weight-bearing systems.
The CXUL.XL harness geometry was carefully chosen to avoid peeling
loads at any angle, in particular at the integrated riser/MLW junction.
Each component of the harness has been load tested individually, as well
as the harness as a whole. The CXUL.XL’s integrated riser design was load
tested to >22 kN in every conceivable load direction.
The CXUL.XL webbing is a blend of Dyneema and polyester. The
Dyneema provides a high level of strength while the polyester provides
structure. Dyneema fiber is durable and more resistant to environmental
factors compared to classic nylon.

If the pack-job appears messy and disorganized, consider redoing it with improved technique.
Your CXUL.XL must be packed cleanly in order to function properly. If you are unsure, do not jump
it. Contact Squirrel immediately with any questions or concerns.
3. You MUST place enough canopy bulk in the upper section of the container to create adequate flap
tension. A significant amount of canopy bulk should be above the top closing loop. Leaving some empty
space at the top of the container will help to keep the top section low-profile and wrinkle-free, but
you must ensure that enough canopy bulk is high enough in the container to make the top edges
of the side flaps lay tightly and securely. Flying at high airspeeds may cause improperly seated or
inadequately tight side flaps to catch air and possibly open the pin cover flap.
4. The second fold should be at the bottom of the container. Leave the parachute bridle attachment point
exposed so the bridle route is clean.
5. When your CXUL.XL is closed, the main pin cover flap should be cleanly seated. Check your placement
of the packjob volume. It should be dispersed evenly from corner to corner and match the shape of the
container. If too much volume is directly under or around the top pin, the main pin cover flap may not seat
properly. Your canopy should be folded into a flat and rectangular configuration matching the container.
6. The small tuck tab MUST be placed below the flap as shown.

Always double check pin tension, orientation, and closure. There are many ways to pack a
container incorrectly. There is one best practice for packing and closing this container. The bridle
should be routed between the grommets, to the top loop, then the bottom. The pins should be
frowning to the right. In this configuration, with appropriate closing loop length, there should be
minimal tendency of pin lock. It is imperative that you close the container as directed (see photos
on the next page).
Pin tension for wingsuit, tracking, and terminal airspeed jumps must be high enough to ensure
secure side flaps and secure pin placement against the relative wind that will be acting on your
container. With the pin cover flap open, you should be able to gently move your container around
on the floor by pulling on the bridle just below each pin, without the pin releasing.

1. Route the bridle from the attachment point on your parachute between the top and bottom
closing loop from left to right. Make sure that the Velcro tab on the bridle is affixed to itself
and free of any twists or knots. Make sure that both closing loops have the washers installed
properly and that they are adjusted to the correct length to provide the correct pin tension
for the volume of your parachute.
2. Insert the top pin through the top closing loop from left to right, “frowning”.
3. The bridle must be flat and free of any twists. Locate and align the bottom pin. Insert the
bottom pin through the bottom closing loop from left to right, “frowning”.
4. Check that both pins are “frowning” from left to right and that the ends of the pins are
pointing to the right.
5. Fold the bridle slack between the top and bottom pin back onto itself along with the closed
Velcro fold. Both of these folds should occur between the top and bottom pins.
6. Hold the Velcro tab and excess bridle between the pins with one hand, while you carefully
close the pin protector flap.
7. Tuck the top of the pin flap and the right side of the pin flap around the left sideflap, tightly
covering the pins and bridle.
8. Tuck the excess bridle under the right-side flap, out of the airflow, routing it towards the BOC.
CONTAINER CLOSURE
PIN TENSION FOR SLIDER UP JUMPING
The CXUL.XL’s packing tray opens into a fully-flat configuration.
To avoid wrinkles or an uneven surface, gently compress the
packed rig to smooth out the container.
The BOC PC is placed in a manner that the handle
of your PC should not be obstructed by the corner of
your container. When you reach back to take it, the
PC handle should be the first thing you touch.

LIGHT BUCKLES
The CXUL.XL features aluminum plate buckles. Be sure to assemble them correctly, and inspect them before
every jump. Webbing must pass around the middle bar of the small buckle. The entire small buckle then
passes through the hole in the larger buckle. Confirm that the webbing fold back end is under (below) the
large buckle’s outside edge.
Do not twist the leg strap before attaching buckles, and as with every other part of your equipment, do a
thorough pre-jump check to verify proper leg and chest strap assembly and routing.
The stopped ends of the leg straps provide resistance in the case of some mis-routings. Obviously, it is
mandatory to check your leg straps before each jump, as normal.

Rappel Anchor Loops are now a standard feature on our harnesses. If you choose to use the SQRL
Rappel Slings, attach the sling to the anchor loop as in the photo below (pass the sling through the
anchor loop, then the sling through its own loop, to form a lark’s foot knot on the anchor).
The two slings should be attached with a locking carabiner. You can then use a rappel / belay
device or a Munter Hitch to rappel.
Note that it is recommended to backup all load bearing systems such as with a sling connecting
your chest strap and the locking biner. Never attempt to rappel without proper knowledge,
instruction, or guiding. The anchor loops and rappel slings are for static weight only, do not use
them as climbing harness anchors and never dynamic load these points.

INSPECTION AND MAINTENANCE
The critical junctions of the CXUL.XL are possible to inspect. All major bartacks are made with
contrasting color thread and are easily accessible. Always inspect your CXUL.XL before each use
and discontinue use immediately if you see any evidence of wear or damage. Always check
your entire container system, and all equipment, for signs of wear or degradation before every
use. NEVER ASSUME that your equipment is in perfect working condition and always use extreme
caution when trusting any single component of your equipment with your life.
