Unlike many later surge suppressors, the SPIKE BAR SK6-6 focuses exclusively on AC power protection and does not incorporate telephone or data-line protection features.

			The SPIKE BAR SK6-6 is a late-1980s surge suppressor design that remained available throughout at least part of the 1990s.

			== Overview ==

			The SPIKE BAR SK6-6 was designed for protecting computers, office equipment, and other electronic devices from power surges and electrical noise. The unit combines six grounded AC outlets, a resettable circuit breaker, an illuminated power switch, and a protected-status indicator in a rugged enclosure intended for permanent installation.
