APTA policy on use of racquets and balls
The APTA Paddle Newsletter reported on the policy that stated that only officially approved rackets and balls would be sanctioned for play at APTA Tournaments.
The only rackets approved for play at the time were manufactured by the Dalton Company, Marcraft and Craig & Simplex Co.
Official balls used at APTA Tournaments were those produced by the Barr Rubber Company.
The APTA told manufacturers, interested in getting their equipment approved, to contact the APTA concerning submission requirements.
