Questions on availability or lead time? Contact Fesler USA before you order and we will confirm it for you.
The Builder 19 puts 19 circuits into a streamlined 6-1/2" x 3" x 2" panel made for under-dash installs where space is tight, such as kit cars, roadsters, and coupes. It uses the same spring steel reinforced terminals found in American Autowire's Highway Series, so a small footprint does not mean giving up capacity for high-draw accessories.
19 CIRCUITS. SLIM UNDER-DASH PANEL. EXTRA-LONG LEADS.
