Introduction 1
Congratulations on purchasing a JumpSport Safety Enclosure! We sincerely believe that you have purchased the finest
safety enclosure on the market. It has been engineered with safety, durability, and performance in mind.
Safe use of a trampoline also requires adequate knowledge of technique, as well as what not to do. Please read this
manual thoroughly for key points of safety.
Trampolines, being rebounding devices, propel the performer to unaccustomed heights and into a variety of body
movements. Therefore, it is emphasized that all purchasers, and all persons using the trampoline, become familiar with
the rules for safe use. Misuse and abuse of this trampoline is dangerous, and can cause serious injuries. The purchaser/
user of this piece of equipment is assuming a degree of risk for which JumpSport cannot be responsible.
Read this information thoroughly before allowing the trampoline to be used. Keep this manual available for your
review, and for review by all potential users. If there are questions please call JumpSport for further explanation.
Caution
Many users of our trampolines are children, and therefore need close supervision and rules to follow while playing on
the trampoline. These rules must be enforced by whomever is responsible for the care of the children. It is strongly
recommended that the buyer of this product go over the rules and recommendations in the packet of information
supplied, including those in this manual. It is also strongly recommended that these rules and recommendations be
supplemented with those of your own, for example: the time that jumping is allowed, when neighbors can visit, and so
on. These rules and recommendations should be reviewed with anyone who is going to jump on the trampoline. If it is
possible, review these rules with the parents or guardians of any visitors who may be jumping on the trampoline. See
Safety Rules (under the Use Instructions section) for more information.

Assembly and Installation
Instructions 2
Preparation
Before you begin assembling your JumpSport Safety Enclosure, make sure your trampoline is in a proper location.
Trampoline Placement
Caution: When deciding on where to place your trampoline, consider the following:
WARNING
Overhead Clearance Adequate overhead clearance is essential. A minimum of 24 feet from ground level
is recommended. Provide clearance for wires, tree limbs, and other possible hazards.
Lateral Clearance Lateral clearance is essential. Place the trampoline and trampoline enclosure away from
walls, structures, fences, and other play areas. Maintain a clear space on all sides of the
trampoline and trampoline enclosure.
Level Surface Place the trampoline and trampoline enclosure on a level surface before use.
Lighting Use the trampoline and trampoline enclosure in a well-lighted area. Artificial
illumination may be required for indoor or shady areas.
Security Secure the trampoline and trampoline enclosure against unauthorized and
unsuperviseduse.
Ground Clearance Remove any obstructions from beneath the trampoline and trampoline enclosure.
Note: The trampoline enclosure is only to be used as an enclosure for a trampoline of a size for which the enclosure
is designed.
Note: The owner and supervisors of the trampoline are responsible to make all users aware of practices specified in
the Use Instructions.
IMPORTANT: The best surface on which to place your trampoline is dirt or grass. However, if you plan to install the
trampoline on a very hard surface such as concrete or asphalt, a dense foam — similar to what can be found in
public playgrounds — should be installed under each leg. Contact JumpSport Customer Service if you have any
questions.
It is the responsibility of the purchaser to become familiar with all of the information in this booklet, to
convey the warnings to all users, and to enforce JumpSport’s rules for safe use.
This unit is not intended for commercial or public use and is therefore strictly prohibited.
The maximum user weight is: 200 pounds (Model 280), 230 pounds (Models 120 & 380), or 295 pounds
(Models 480 & 480XT), or the specified user weight rating of your trampoline, whichever is lower.

Assembly and Installation Instructions
Tools
Installation of the safety enclosure requires a 10mm deep socket and ratchet, or a crescent/adjustable wrench. An 8 foot
A-Frame ladder will be useful for some steps (use care and follow procedures for use). Safety glasses and gloves are also
recommended for safety.
Parts List
Your JumpSport Safety Enclosure is shipped with the parts shown below. Some parts will be located in a smaller inner
box. If any parts are missing, immediately call JumpSport Customer Service at 408-213-2551.
Note: Do NOT discard the foam tubing (Reference #3 and #4); it is needed to make the pole assemblies. It is not
just packing material. Not all poles will have foam around them. And do NOT remove any caps from the ends of any
of the support poles.

2) Using the hardware provided, connect a pole to the outside of
each trampoline leg:
• If you have a JumpSport Trampoline, bottom of pole must
line up with red mark on vertical leg piece. This will ensure
that pole is at proper height. (If red marks are missing, see
below.)
• If you do not have red marks on your trampoline legs, the
safety enclosure pole should extend 73 inches (6 feet 1 inch)
above the jumping surface (mat), as shown above.
• Align notch in ball end cap with rail as shown above.
• Bottom U-bolt should be approximately 2 inches above
bottom of pole.
• Snugly tighten Nylock nuts.
• Hand-tighten acorn nuts.
3) Wrap cable tie around U-bolt cap cover and pole. Secure cable
tie to hold cap cover in place.

5) Top strap of net is slightly wider than bottom strap. Wider
strap must be at top of net. Place looped end of top strap of net
around ball end cap at pole 1. Pole 1 must be at a right vertical leg
piece.

6) Hang net clockwise along the inside of pole 2. Top strap and 1
mesh of netting must rest in groove on top of ball end cap. Top
strap should hang slightly curved between poles 1 and 2.
4) Familiarize yourself with the net. The net has a wider strap at the top of the net. There are red marks on the top and bottom straps
of net to help with installation. However, the red marks will NOT line up with the poles if you do not have a 14ft or 16ft trampoline. If
you have a 480XT net, there will be no red marks on the straps at all.
IMPORTANT: There are knots in all 4 corners of the net. These knots should not be removed for any reason, and are required in
order for the net to install properly.

10) At starting edge of net (where you first hung the net on pole
1), find the bottom corner. Pull bottom corner toward pole 1.
Wrap bottom strap of net around pole 1, below rail of trampoline,
as shown. Secure with a strong knot.
Note: When you are done, the strap should be wrapped and tied
so that there is no excess hanging.
8) Continue back to pole 1. Hang net around outside of pole 1,
with top strap and 1 mesh of netting resting in groove on top of
ball end cap. Then pull net to pole 2. Wrap net around inside of
pole 2, around neck of ball end cap, and double it back on itself
toward pole 1. Then net will be able to pull back to pole 1 or even
pole 8.
Note: Bottom of net in some locations may not be touching
trampoline at this time. This is normal.
7) Now hang net clockwise around outside of all remaining
poles. Top strap and 1 mesh of netting must rest in groove on top
of ball end cap. Top strap should hang slightly curved between
poles.

9) Feed top strap through top of net near pole 1 (or pole 8 if net
itself can be pulled past pole 1). Wrap top strap around ball end
cap to secure it. Then tie a double knot in the strap. Loosely wrap
excess strap around pole 1 (or pole 8), and tie off loose end as low
on the pole as you can.

13) At outer panel of net, pull the bottom corner strap straight across to same pole that you tied top of net to in Step 9. Wrap bottom
strap around this pole and secure with a strong knot.
Note: When you are done, the strap should be wrapped and tied so that there is no excess hanging.
12) Find pole that you tied off to top of net in Step 9. Lift frame pad between that pole and pole to left of it. Tuck pad skirt up
underneath pad, so skirt is wedged between bottom of pad and rail of trampoline.
Note: If you attached your net to pole 8 in Step 9, then you also need to tuck pad skirt up underneath pad between poles 1 and 2.
Note: All the pictures in this
manual show the net tied off to
pole 1, for illustrative purposes.
However, your net may be tied off
to pole 8 instead of pole 1.

15) Starting at pole 2 and working clockwise around trampoline, pull bottom of net down pole, so that bottom strap of net is
positioned below bottom of pole foam. Wrap a 1ft bungee around bottom strap of net, then around trampoline leg, and connect ends
of bungee together under trampoline frame. Ignore red marks on bottom strap if there are any.
>> Repeat at all other poles, continuing to work clockwise around trampoline.
