The GAEP BN2 is listed by the manufacturer as a star-crimp finisher. This article covers product identification and purchasing questions.
Confirm the exact model
GAEP lists BN1, BN2, BN3 and BN4 as separate models. The BN2 listing should identify the actual model supplied. A photograph showing several finishers does not establish which model is included.
Check your selected gauge
The ShotCrimp BN2 product page currently lists gauge options. Select the required option and review the cart description before purchasing.
Check the mounting details and included items
Confirm the mounting connection and whether an adapter or other accessory is included in the specific offer. See the separately listed GAEP Universal Arbor and accessories collection; do not assume a separately listed item is bundled with the BN2.
Different closure types
The manufacturer identifies BN models as star-crimp finishers and the steel OTP as a roll-crimp model for plastic cases. View the OTP product page if you are comparing product types.
