Short answer

Sunny Health & Fitness lists a 3/4 in hardware peg hole diameter on the SF-XF9933 half rack, so it is neither a 5/8 in nor a 1 in system. Sunny's SF-XFA002 dip bar attachment is listed for named Power Zone models and rated for up to 330 lb of user weight, and the overview and spec table name different model lists. Sunny's attachments list Sunny models, so buy by your model number.

  • The SF-XFA002 dip page names two different model lists. If your model is on only one, confirm with Sunny before ordering.
  • Sunny rates the SF-XFA002 for up to 330 lb of user weight and describes its retention only as 'Hook & Lock'.
