Gripping the String

While holding the tension bar slightly above 
horizontal, wrap the free string clockwise 
around the gripper drum once and position 
between the gripper jaw.

Gently turn the gripper clockwise while 
squeezing the jaws together until all slack 
in the string is removed.

Note:

 For proper operation, the string grip-

per jaw must be in the position shown. The 
tension in the string provides the clamping 
force to the jaws.

Getting Started

To begin stringing the main strings, thread 
the two ends of the string through the two 
center holes at the appropriate end of the 
frame and continue through the opposite 
center holes. Thread one end of the string 
through the adjacent grommet hole and pull 
excess by hand.

Secure one of the strings using a string clamp.

Handy tip: The tear drop shaped holes 
towards the back of the shoulder supports 
are handy for holding the loose end of the 

string while tensioning the string. Simply insert the loose end into the tear drop shaped holes 
and slide the string toward the point of the hole.

Base Clamp Operation 

Rotate the lever lock clockwise to secure 
the clamp base to the turntable.

Reverse the clamping procedure to unlock 
the string clamp.

The lever should be tightened enough to 
prevent clamp base slippage on the turn-
table, when the desired tension is placed 
on the string. To go from the loose position 
to the clamped position and back, gener-

ally requires about 1/2 to 3/4 quarters of a turn.  Although when stringing at extremely high 
tensions, additional tightness may be required.

STRINGING THE FRAME

STRINGING THE FRAME

WARNING:

 

TO AVOID INJURY, KEEP FINGERS AWAY 

FROM GRIPPER JAWS WHILE TENSIONING STRING.

Pulling Tension

While securely holding the string gripper drum 
with your hand, lift the tension bar  above 
horizontal and gently lower the bar under its 
own weight. If the tension bar drops below 
horizontal, repeat the above action until the 
bar comes to rest parallel to the racquet.

When the correct tension is attained, the drop 
weight bar will rest horizontally as shown.  For 
accurate tensioning, it must be lowered and 
come to rest at horizontal without assistance. 
Manually forcing the tension bar to the hori-
zontal position will greatly increase the  string 
tension and may result in racquet damage.
If the tension bar comes to rest above hori-
zontal, release the string by lifting the bar 
and re-pull the string.

Clamping the First Main String

Secure the tensioned main string using the 
second 

fi

 xed clamp. Repeat the procedure 

for all of the remaining main strings and tie off 
at the appropriate hole following the racquet 
manufacturers speci

fi

 cation.

Follow the racquet manufacturer's recom-
mended stringing pattern for one or two piece 
stringing. This will determine the starting 
point for the cross strings. If applicable, tie 
the 

fi

 rst cross string using an appropriate 

starting knot.
