All FLEX polishers include a bale handle. If you prefer a side handle, you can easily replace the bale handle with this FLEX Polisher Side Handle. It's made by FLEX for FLEX polishers. If a side grip is more comfortable to you, you may experience decreased hand fatigue and better control over your technique simply by switching out the handle. The FLEX Polisher Side Handle fits all FLEX polishers and can be installed on either side of the machine. It can be removed and replaced as needed.
