Thru-Bulkhead Terminal Block

These are small footprint terminal blocks for your forward and aft avionics bulkheads. These are designed around the same principle as our combined Charge Well/Terminals, using the mounting screws as the conductor through the bulkhead. These allow you to use most any Charge Well on the market. The kit includes a pair of terminal blocks, stainless steel hardware to mount them and 6” ring lug wiring pigtails. Like our Charge Well/Terminals, the ring lugs are available precrimped or as pieces (uncrimped) to allow you to add them to your existing wiring.

The kits come with small format 4-40 nuts and we provide a couple extras in case you drop one on the grass.

NEW: We now offer an alternative to the small format nuts to make field use a little easier. These are small brass knurls nuts that are easier to grip.

WARNING: The mounting screws are part of the electrical circuit and need to be protected from shorting by metal objects (Quick Links, metal tape, aluminum bulkheads, etc) or your altimeter will not work. We recommend wrapping the the screws with electrical tape to aid in preventing inadvertant shorts. If you are mounting to aluminum/metal bulkheads we offer screw isolators designed to insulate the screws from the bulkhead.
