Zerc Drive Tool is a punch like device used to field install barbed
zercs in Resi-Mizer Injectors or directly into metal substrates
such as corrugated metal pipe and steel plates to be injected. The
recessed zerc grip engages each fitting dependably and allows driving
without damage to the zerc's check ball. The knurled finish helps
with driving without damage to the fingers.
