Material
Aluminum alloy or tin-plated copper; non-precious base metals with steel hex-head set screws
Dimensions
Approx. 10-15cm in length; heavy industrial weight (kg range)
Description
This is an industrial electrical component, not an antique or household silver item. It features stacked terminal blocks for high-voltage electricity.
Key Features
Layered metallic plates, hexagonal set-screw terminals, and square-profile housings.
Material & Composition
Aluminum alloy or tin-plated copper; non-precious base metals with steel hex-head set screws
Finish & Decoration
Dull, oxidized industrial finish with no decorative elements; significant surface grime and grease
Hallmarks & Stamps
No silver hallmarks; may contain UL listing numbers or industrial part codes
Construction Details
Extruded or cast metal housing with threaded mechanical fasteners for wire tensioning
Functional Features
Mechanical lug connectors for high-gauge electrical conductors; hex-driver recessed set screws
Handle & Grip Details
None; purely functional industrial design
Craftsmanship Details
Function-first machine-milled and cast construction with no hand-wrought elements.
Authentication Indicators
Identification as industrial equipment based on mechanical screws and absence of hallmarks; high-stress industrial design language.
Origin & Manufacturing
Mass-produced industrial assembly, likely fabricated in standard global industrial hubs
Era & Period
Modern Industrial / Late 20th to 21st Century
Age Estimate
Circa 1990-present day; shows significant usage and environmental wear
Cultural Significance
Impact limited to modern electrical infrastructure and power distribution.
Condition Notes
Poor; heavily soiled with dirt and grease, significant oxidation, and potential mechanical wear. Grade: Damaged/Used
Value Estimate
Negligible antique value; scrap value only ($1-$5 based on weight of aluminum/copper).
Care & Maintenance
Not applicable to silver collectors; requires degreasing if being salvaged for base metal scrap.
