Confirm the customer section. Confirm 2″ / 50.8 mm and lock geometry before any tool touches paint.
Choose single or double lock
Choose single or double lock
Use the two-stage board. Train which pass stops at 90° and which continues to 180° wrap.
Clip engagement context

Specification includes the clips the customer already uses. Confirm that the seamer clears the clip and avoids crushing it—clip forming stays on its own page.

Manual tongs (when in package)
