Playmate Tri-Knob Screws

Playmate Ball Machines, Ball Mowers and Serve Lifts use two different Tri-Knob screws. The smaller sized handle is on the smaller diameter screw. Choose from the following two sizes, depending on your Playmate equipment.

Small 1/4" Diameter

• Ball Mower handle
• Serve Lift safety rod
• Handle on older machines

Large 5/16" Diameter

• Handle on the current ball machine

Please Note: A third and shorter type of tri-knob screw is used to attach the control box to the machine. Please contact us for more info or if you need assistance.
