Parts Desk Insights
The BSS-1990 is the go-to choice when a customer needs a high-current positive or negative bus with a manageable number of connection points — 8 studs covers most single-engine or mid-size twin-engine installations. Customers building out a larger system or needing more termination points should consider the BSS-1991 12-stud version. The included cover is an important safety feature; confirm the customer is aware it ships with the busbar to avoid duplicate cover orders.
