UNSPSC 39122107: Wood wiring block

Timber used to attach distributing wire device inside of a house.

UNSPSC 39122107 Wood wiring block is a Commodity code that captures electrical and telecommunications infrastructure materials used in utility construction and maintenance. State and local governments procure wood wiring blocks as subordinate components within larger utility and infrastructure projects—installing them as part of underground conduit systems, pole-mounted electrical equipment assemblies, and telecommunications infrastructure installations. The code sees activity primarily from county and municipal utilities, transit authorities, and special-purpose electric cooperatives conducting right-of-way maintenance, utility relocation, and infrastructure upgrades. Issuing bodies span municipal purchasing divisions, county utilities departments, electric cooperatives, and state transportation agencies.

Recent opportunities show fragmented geographic spread with no standout concentration. Orange County, Florida (Horizon West Trail - Phase 1A, IFB, due August 13, 2026, $5.66 million estimated) involves utility improvements including water main replacement within a multi-use trail project; Pasco County, Florida (underground utility locating services, IFB, due June 30, 2026) addresses utility asset inventory; the City of College Station, Texas (State Highway 6 utility relocation, RFP, due April 29, 2026) includes water and wastewater line installation under highway corridors; and Glades Electric Cooperative, Florida (vegetation management contracts, RFP, April 2026) covers right-of-way clearing under energized power lines. Additional activity includes the Orlando Utilities Commission (joint use and streetlight attachments inventory audit, RFP, due December 4, 2025), the City of Madison (20-foot galvanized poles for street lighting, RFQ, due March 10, 2026), and the State of Oregon Department of Transportation (ductile iron poles, ITB, due March 11, 2026). The recent opportunities do not indicate high-volume solicitation of wood wiring blocks as standalone line items; instead, the code appears underutilized or miscoded relative to the infrastructure work actually being purchased.
