STEP 1 

Begin by using a small phillips heads screwdriver to open and stretch the hold on the top of the grip on your putter. If you have difficulties inserting the screwdriver in the putter try a little lubricant.

STEP 2

Next insert the Golf Hoop into the putter's handle.

STEP 3

Push pin in all the way to the undercut part of the pin, under the head. 
This tapered edge will prevent the pin from falling out of the handle since it will snap into place.

STEP 4

Golf Hoop is now inserted and ready for use. 
Open and close Golf Hoop from tapered edge only to retrieve ball from hole.

STEP 5

 
When putting the ring can be turned so it doesnt interfer.
It is made to open and close from the tapered side only for the best operation.
