The rocker power switch closely matches the design used on the archive's 1994 PRO7 specimen.

	~~Comparison with~~ the archive's ~~1996 specimen suggests that the raised switch-position markings were originally produced without contrasting paint fill and may represent normal factory appearance rather than wear-related loss~~.		The documented 1996 specimen appears externally and internally very similar to the archive's 1994 PRO7 example.

	The documented 1996 example establishes that APC continued manufacturing PRO7 units based upon the original ©1993 design generation for at least two years after the archive's earliest documented specimen.		Both examples:

	~~This narrows~~ the ~~transition period between the original~~ design and ~~the later ©1996 suppression-board revision documented in the archive's 1998 specimen~~.		* Utilize suppression board 640-0321 REV 2.
			* Carry a ©1993 American Power Conversion copyright notice.
			* Utilize unbranded straight-blade attachment plugs.
			* Lack internal date-code wheels.
			* Employ the same enclosure design and indicator arrangement.
			* Exhibit nearly identical weights (1 lb 14.8 oz vs. 1 lb 14.7 oz).

			These similarities suggest that APC made few, if any, substantial design changes to the PRO7 between the documented 1994 and 1996 production examples.

			The archive's 1998 PRO7 specimen introduced APC's documented ©1996 suppression-board generation, indicating that the transition away from the original 640-0321 REV 2 design likely occurred between 1996 and 1998.

			The straight-blade NEMA 5-15P attachment plug is unbranded and closely matches the design documented on the archive's 1994 PRO7 specimen. Later documented PRO7 examples transitioned to APC-branded attachment plugs and revised plug designs.

			The documented APC PRO7 weighs approximately 1 pound 14.7 ounces (842 grams).

			The measured weight is nearly identical to the archive's 1994 PRO7 specimen, which weighed approximately 1 pound 14.8 ounces. The minimal difference suggests that APC had not yet made substantial changes to the enclosure, cord assembly, or surge-suppression architecture between the two documented examples.

	~~Weight discussion and comparison with related products~~.		The weight also places the 1996 specimen among the heavier members of the PRO7 family documented by the archive, preceding the gradual weight reductions observed in later generations.

	The rocker power switch matches the style used on the archive's 1994 example. Examination of both units suggests that the molded "I" and "O" switch-position markings may have been produced as unpainted raised features rather than white-filled markings that later faded from use.

			The enclosure measures approximately 10.25 inches long, 4.25 inches wide, and 1.75 inches tall.

			The documented example retains the early rounded-top Professional SurgeArrest enclosure design previously observed on the archive's 1994 specimen. The housing combines a curved upper section with a rectangular outlet assembly containing seven grounded receptacles arranged in a single row.

			Like the 1994 example, the unit uses a straight-blade grounding attachment plug without APC branding. Later documented examples transitioned to different plug styles and APC-branded attachment plugs.
