	The documented example weighs approximately 1 lb 1.5 oz (496 g).		The documented example weighs approximately 1 lb 1.5 oz (496 g).

			The documented example also weighs approximately 1 lb 1.5 oz (496 g), noticeably more than the archive's documented Universal 71632 but slightly less than the telephone-protection-equipped Universal 71637. The additional weight is consistent with the larger surge-suppression assembly and revised enclosure design observed during teardown.

Inspection of the documented example revealed dust accumulation and cosmetic contamination consistent with long-term use, but no obvious evidence of overheating, melting, or catastrophic electrical failure.

			The outlet assemblies are retained within molded supports integrated into the lower housing. Power distribution is accomplished using stamped brass bus bars that run the length of the enclosure and feed all six outlets, including the dedicated transformer-spaced outlet.

			The upper housing incorporates additional reinforcing ribs, outlet barriers, and support structures that maintain outlet alignment and provide rigidity to the enclosure.

			The transformer-spaced outlet is integrated into the same bus-bar distribution system as the remaining outlets and does not utilize separate wiring or dedicated circuitry.
