{"product_id":"premise-wiring-s1sp4x4-poke-through-sub-plate","title":"Premise Wiring S1SP4X4 Poke Through Sub Plate","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe PREMISE WIRING S1SP4X4 is a modular sub plate designed for use with SystemOne floor boxes and poke-through assemblies. It provides four 125-volt, 20-amp receptacle positions along with four keystone openings in a single round plate, giving electricians a flexible, reconfigurable solution for floor-level power and data access. The plate is constructed from cast aluminum and measures 5.36 inches in diameter by 0.22 inches in height. It mounts via a flange in flush-service configurations and carries UL approval for both the US and Canada. Installation is straightforward for licensed electricians working in commercial office, education, or multi-tenant environments where floor box systems are common.\u003c\/p\u003e\n\u003cp\u003eThe S1SP4X4 sub plate inserts into a universal SystemOne cover, allowing contractors and specifiers to build application-specific combinations without replacing the entire floor box or poke-through assembly. The modular design supports future moves, adds, and changes economically — the sub plate can be swapped out while the base infrastructure stays in place. This makes it well suited for commercial interiors where tenant configurations change over time. The four keystone openings accept standard low-voltage inserts, enabling data, audio, or video connections alongside the four 20-amp receptacles in the same footprint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour 125-volt, 20-amp receptacle positions in a single sub plate\u003c\/li\u003e\n  \u003cli\u003eFour keystone openings for low-voltage inserts such as data, audio, or video modules\u003c\/li\u003e\n  \u003cli\u003eCast aluminum construction for durability in floor-mount applications\u003c\/li\u003e\n  \u003cli\u003eFlush service type with flange mounting for clean, low-profile installation\u003c\/li\u003e\n  \u003cli\u003eModular design allows sub plate swaps without replacing the full floor box or poke-through\u003c\/li\u003e\n  \u003cli\u003eUL listed for use in both the US and Canada\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Hubbell SystemOne floor boxes and poke-through assemblies.

Power down the circuit and verify zero voltage at the floor box before handling any wiring or sub plate components. The flange mounting style requires the universal SystemOne cover to be in place prior to sub plate insertion. Keystone inserts are field-installed separately and should be rated appropriately for the intended low-voltage application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDevice Type\u003c\/strong\u003e: (4) 125 V 20 Ampere Receptacle, (4) Keystone Opening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 125 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlate Diameter\u003c\/strong\u003e: 5.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlate Height\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eService Type\u003c\/strong\u003e: Flush\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL (Canada and US)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: US\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PREMISE WIRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S1SP4X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PREMISE WIRING","offers":[{"title":"Default Title","offer_id":51283972915506,"sku":"S1SP4X4","price":259.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279339.jpg?v=1781064658","url":"https:\/\/voomisupply.com\/products\/premise-wiring-s1sp4x4-poke-through-sub-plate","provider":"Voomi Supply","version":"1.0","type":"link"}
