If you have a Gamma Tennis Stringer Stringing Machine with the 6mm hex bolt to adjust & move the tower arms, then this is the simple upgrade you need.

This listing includes 1 MATCHING PAIR OF BLACK LEVER LOCKS, one for each of the 2 Gamma Tower Arms (see photos).

This lever lock upgrade allows you to adjust/slide the Gamma tennis stringer tower arms without the need for the 6mm hex/allen key tool.

Once installed (takes about 5 mins) you will just do a 1/4 turn to loosen the lever lock, then slide the arm & then the reverse 1/4 turn to tighten the lever lock for a simple & easy tool-less adjustment.

This will save you time looking for the 6mm hex tool & constantly making the Tower width adjustments for each string job going forward!

You will get 1 matching pair of black lever locks, you will just need to let me know which of the 2 styles you want (they both function the same)

Style 1 - Silver phillips screw top

Style 2 - Black 3mm hex screw top

Please look at photos
