PRODUCT DETAILS Make one test hole using using a brad awl in the
position marked + in the following sketch--about 7mm in from the edge
as indicated by the circle. Then insert a 3 or 4mm screw into this
hole. If it goes in and seems firm, you can be reasonably certain that
Acedge will fit onto your racquet. You could also try it on an old
racquet first.
Acedge is held
by four screws on the bottom of the racquet handle. Clearly it will not
fit if your racquet has an open end to the handle. If your handle has a solid end,
there should be no problem whatever and you will soon be on your way to hitting more service winners. Full instructions are detailed in the product package.

In the figure below you can see an Acedge mounted
for a right handed player. When the player is facing the net, prepared
to serve, Acedge will be close to his or her body with the edge of the
right hand resting upon the rubber edge corresponding to side 2 above.

You will note that this side 2 is slightly longer than side 1 and this
is another guide for correctly fitting Acedge on the handle. The device
is simply flipped over for left handed players and fitted across sides
6 and 7.
