Physical Description
The Universal 71641 utilizes a beige plastic enclosure with six grounded outlets arranged in a single row.
The outlet nearest the end of the strip is spaced farther from the adjacent receptacle to accommodate transformer-style power adapters and oversized plugs.
A rocker-style RESET/OFF power switch and surge-protection indicator are located near the power-cord entry point.
The documented example exhibits significant yellowing of the enclosure. Areas surrounding several outlets have retained noticeably lighter coloration where plugs remained inserted for extended periods. The pattern suggests long-term use with multiple two-prong devices connected to the unit.
The yellowing pattern appears consistent with prolonged use of multiple two-prong devices, which shielded portions of the enclosure from the aging processes affecting the surrounding plastic.
