Performance Plus Connection D-sub Dt Series Deutsch Crimping Tool 20-12 Awg, Red, Ergonomic Grip

If I am understanding this correctly, using 12awg wire, you would not be able to crimp a contact on each end? And you need access to both ends?

Does it ratchet shut like the real crimpers

Will these work for the deutsch dtp 12-14 gauge solid connectors?

hi, is it compatible with the dsub pins?
