The FullStop® Gemini Wheel Lock is designed to secure twin axle caravans and trailers by
locking onto both axles via replacement wheel nuts. Fixed securely to both axles, the Gemini
then prohibits normal wheel rotation and consequent movement of the vehicle.
1. Before the product can be used, two of
your existing wheel nuts must be removed and replaced
with Receiver Wheel Nuts (9 or 10). These replacement
nuts have been designed to fit the majority of caravan
and trailer wheels, however, please check that your
existing wheel nuts are of the same specification. The
sizes of the supplied Receiver Nuts (9,10) are 1/2"-20
and 9/16"-18. If in any doubt consult the vehicle
manufacturer or wheel supplier BEFORE installation as it
is possible to damage the hub of the vehicle if the
screw threads do not match.
To fit the two necessary receiver nuts (9,10), two of
your existing wheel nuts will first need removing.
When choosing which two to remove, opt for the
inner most wheel nuts on each wheel (see Fig.D
and Fig.E for guidance). Where the Gemini Wheel
lock can be fitted to any two wheel nut locations,
this positioning is the optimum for initial installation.
Receiver Wheel Nuts (9,10) can be fitted using the
Wheel Wrench Adapter (8) which enables you to
use a standard 19mm wheel wrench (see Fig.B).
The Receiver Nuts (9,10) should be tightened to the
correct torque setting for your wheels.
Do not over-tighten or use an impact
wrench on receiver wheel nuts. Check
your Owners Manual for details or
consult a qualified technician.

2. To prepare the Gemini for fitting, the required length must first be determined and adjusted accordingly. To do
this, both Locking Portions (3) will need installing for use as guides. Using Fig.A for reference, install the Locking
Portions (3) into apertures in the head of both the Outer (1) and Inner Tubes (2). Each Locking Portion (3) can then
be secured in place by tightening the Locking Portion Hex Screw (5) using the supplied 3mm Hex Key (6)(see
Fig.A for reference).
Next, hold the device up to the wheels, and line the Locking Portion (3) in the head of the Outer Tube (1) up with
the Receiver Nut (9,10) in one of the wheels. From here, gauge whether the length of the Gemini needs to be
longer or shorter to allow the Locking Portion (3) in the head of the Inner Tube (2) to line up correctly with the
Receiver Nut (9,10) in the second wheel (see Fig.F for guidance).
To adjust the length of the Gemini Wheel Lock to suit your vehicle, grip the Outer Tube (1) in one hand, and
proceed to rotate the Inner Tube (2) in the desired direction (see Fig.C). Use the arrow graphic on the product for
reference. Whilst adjusting the length of the Gemini, periodically offer the assembly up to the Receiver Bolt
(9,10) in order to correctly judge the required length. Each 360° rotation of the Inner Tube (2) is approximately
equal to 1.5mm of length adjustment within a fitting distance range of minimum 510mm and maximum of 825mm
(distance between centre of receiver wheel bolts).
NOTE: When shortening the length of the Gemini,
ensure that if resistance is met, you do not
continue to attempt shortening. This has likely
occurred as the minimum length has been met. If
in this state the assembly is too long, consider
relocating the position of your Receiver Wheel
Nuts (9,10) to allow for a wider installation length.
3. Before using the device it may be necessary to add
Spacer Rings (4) to ensure that, when fitted, the ends of
the locking portion tubes are as tight as possible to the
face of the wheel when the Locking Portion (3) is locked
into a Receiver Nut (9,10). To check this, first fit both sets
of keys (7) into their respective Locking Portions (3) and
rotate them through 90° clockwise to release the locking
ball bearings.
Offer up the assembly to the Receiver Nuts (9,10), guiding
the end of the Locking Portions (3) in as far as they will go.
Lock them together by rotating the keys (7) anti-clockwise
through 90°, then remove both keys (7). The aim at this
stage is for the heads of both the Inner (2) and Outer
Tubes (1) to be as tight as possible to the face of the
wheels, when the Locking Portions (3) are locked into the
Receiver Nuts (9,10). Achieving this will mean that the
Gemini will be most effective; protecting and preventing
access to the Receiver Nuts (9,10) when locked in place.
(Fig.G)
If there is a gap, or the assembly can be pulled away from the face of the wheel, making the Receiver Nuts
(9,10) visible, then Spacer Rings (4) must be used. Try to gauge the amount of gap and add the necessary
amount of Spacer Rings (4) between each Tube (1,2) and respective Locking Portion (3) as shown in Fig.A.
Always add an equal sum of spacer rings (4) to each Tube (1,2) .To fix these in place, use the supplied 3mm Hex
Key (6) and tighten the Locking Portion Hex Screws (5) into the most applicable of the two available holes in each
Tube (1,2) (see Fig.H). The Hex Screws (5) should be tightened to the bodies of the Locking Portions (3) to
correctly secure the spacer rings (4) in place.

4. The Gemini Twin Axle Wheel Lock is now ready for
use (Fig.I). Please check Receiver Nut (9,10) torque
setting after the first 100 kilometres (approx) and at
regular intervals thereafter.
NOTE: In use, some wheel rotation will occur before the Gemini Wheel Lock fully immobilises both
axles, thus preventing movement of the vehicle.
TIP: To reduce the amount of length adjustment required between each use, it is possible to add a
second Receiver Nut (9,10) onto each wheel. When doing this, we advise locating the second
Receiver Nut (9,10) in opposing positions to the original Receiver Nut (9,10); this will allow for a
wider range of fitting positions. As per section 1 of this manual, the lock body should still be fitted
to the closest two Receiver Nut (9,10) to prevent excess unwanted wheel rotation.
We do not recommend replacing any more than
two wheel bolts on any given wheel.

INSTALLATION (CONT.)
Grease the lock face and ball bearings before rst use, with a light oil such as 3-IN-ONE or equivalent.
Thereafter spray any moving parts of the lock body with a light oil such as 3-IN-ONE or equivalent every
eight weeks.
Any light scus on the gloss surface of the body can often be bued out with a cloth.

MAINTENANCE
PRODUCT REGISTRATION
During general use, the length of the Gemini Wheel Lock
may need adjustment to suit various receiver nuts
locations. In these cases, adjust in the same manner as
during set up (Fig.C). Once installed as per this manual,
elements such as the Spacer Rings (4) and Receiver
Nuts (9,10) fitting should not require amendment, except
for maintenance purposes.
