Please read this page carefully. This isn't your usual
product disclaimer. It has specific product safety and
Warning: Slacklining is a potentially hazardous sport. Any
person using Slackline Express products is responsible for
learning the safety techniques, assuming all risks, and
accepting full and complete responsibility for their choice
to participate in a sport that could involve property
damage, and injuries including death. Failure to use proper
safety technique can lead to serious injury or death.
Remember, this is a sport of balance and learning to fall is
part of the sport so risk is a factor. Due to the known
risks of these types of gymnastic and height related sports,
the participant must assume all liability for their own
We strongly recommend you start off walking the slackline at
low heights of two to four feet off the ground with a soft
pad or grass to land on and that you utilize spotters to
assist in preventing injury. Never let a child or
inexperienced slacker get on a line without spotters. They
need the extra help to make sure they don't get hurt. One
spotter should be on each side of anyone new to the sport.
Always ensure the line is secured and that you have
something to fall on, or you could easily hurt yourself. If
you have ANY doubt that the anchors are secure, the
tightening system is working correctly, and that the webbing
is safe, DO NOT USE IT. If you have any questions as to what
is safe, give us a call. Seriously, we don't mind a call or
email; it's much better than one of our customers being
Avoid getting webbing wet. If you do get it wet, make sure
to dry it well, or it could rot and weaken the system.
Inspect your webbing and gear before each use.
Check your tree slings and main line carefully for abrasion.
Never use frayed or otherwise damaged webbing.
Always pad your webbing from abrasive edges or tree bark.
These will slowly destroy your webbing and lead to failure.
If and when the webbing has become abraded, it should be
retired and replaced (we will be happy to replace it for you
as cheap as possible). Assessing abrasion is difficult. See
FAQs for more details.
Never overload the line beyond normal use of one or two
people walking the line or use the slackline for any other
use than for normal slackline walking. You can and probably
will get hurt if that line breaks, as they are under large
tensile loads. We've tested each of our products
extensively. They should perform fine within the parameters
we've set forth on the product information page and this
safety page. However, when not used as instructed, many
things could lessen the strength of the kit including age of
the kit. Follow the guidelines; itís for your safety.
The intro and deluxe kits are both fine for two people and
big jumps, as long as you keep the stress load under 1800
lbs. Jump mounts are fine as long as they are at reasonable
heights. For additional information on calculating safe
loads, contact us with your setup information. You can also
use our slackline
tensile force calculator.
Tensile load increases as:
the line gets tighter (less sag in the line while
the line gets longer
more weight (or force from tricks or jumps) is
placed on the line
Never leave your slackline in the sun for long periods; UV
rays can weaken most any gear.
Keep your gear clean. Dirt and grit gets into webbing and
can grind away at it just the same as climbing rope.
Over time if the tightening system gets stiff and harder to
use, you should oil the gear mechanism and the part that
slides into the teeth. Standard household oil will work, but
we've found lithium grease in the spray cans works best and
is cheap. Just make sure to clean up the excess before
letting webbing touch it. This really isn't a safety issue
per say but is always a good idea to ensure smooth
Old kits that we've sold with the steel ring style
adjustable tree slings should not be used on extremely tight
lines. Instead, retie the knot higher up or use additional
wraps around the anchor.
Never let the webbing get pulled up the side of one of the
ratchets. It will chew it up if you get it in the teeth.
Follow the product instructions on keeping it from going up
If you retie any tree sling knots, ensure you use secure
knots, such as an overhand on a bight, bowline knot or a
figure eight. Instructions are included with the kit for the
bowline knot and are available on this Web site. The "tail"
should be on the inside of the loop and be at least two
inches long. If the tail of the knot has slipped over time,
it should be retied to ensure a long enough tail is
available to secure the knot. Contact us for other knot
If you start to fall, try just stepping to one side. You
should come down cleanly rather than falling straight down
and letting the webbing snap you. If youíre going to fall
hard, keep your arms in and fall in a roll. Youíre more
likely to break a bone if you try and brace yourself. Take
precautions to avoid falling on your neck or head. Take
necessary precautions, such as lots of padding and spotters,
to avoid critically injuring yourself. If youíre doing risky
tricks, always have a large, soft crash pad.
You should always use a harness and a fully redundant safety
system for any elevation higher than a comfortable fall.
Our standard kits are not meant for highline walking (slacklining
above safe falling height) and have not been approved for
such use. This line is not intended for climbing, use as
life line, or any other purpose than slackline walking. By
purchasing a kit from us, you are agreeing to follow these
guidelines and accepting that you are responsible for your
own actions while using this product. Everything we sell has
a proper way of being used but when used improperly or
carelessly may lead to personal injury.
By purchasing this kit, you have agreed to participate in a
potentially risky activity. You, therefore, are assuming
responsibility of your own actions as well as ensuring that
you will abide by the guidelines we set forth for checking
the safety of the line and using it responsibly. If you do
not agree with this safety disclaimer, do not purchase our
product. If you have already purchased it, send the kit back
immediately for a refund (refunds amounts vary depending on
if the line has been used or not).
