2 1/2 Inch PVC Coupling Slip x Slip
This fitting can be used as part of a tennis ball barrel adapter or used to join tennis ball barrels together for an extra long barrel.
Optional Machining
A great way to improve the looks of your launcher and make your friends jealous.
Machining cleans up the fitting by removing the markings from the end of the fitting and also removes the ugly nub that is left over from when the fitting was made.
