Thomas & Betts / Blackburn

Overview

Thomas & Betts (T&B) is a long-established North American manufacturer of low-voltage installation products and fittings. Blackburn is the T&B-branded line commonly used for overhead distribution connectors, wedge clamps and grounding hardware. Together these names are widely referenced in contractor and utility specifications for field-ready connectors and service-entrance fittings.

What the brand is known for

T&B is known for practical, contractor-focused products that simplify wire and cable routing, connection and protection. Typical strengths include conduit and service entrance fittings, mechanical and compression connectors, wedge and service clamps, grounding plates and a range of mounting consumables.

Main product families and technologies

• Service entrance and conduit fittings: clamp-on and threaded service caps, bodies, elbows, covers and gaskets sized to trade conduit and hub threads.
• Mechanical and compression connectors: lugs, splices and tees for aluminum and copper conductors.
• Wedge clamps and service wedges: Blackburn W-series wedge clamps and sliders for overhead drop attachment.
• Grounding and bonding: ground plates and clamps for equipment and structural grounding.
• Mounting and hardware: jack chain, conduit-to-flange clips, nylon clamps and related consumables.

Common applications

Typical uses include residential and commercial service entrances, utility overhead distribution, industrial maintenance and OEM installations where reliable conductor connections and conduit transitions are needed.

How to identify and specify models (procurement tips)

• Catalog numbers: record the full catalog number including suffixes (example: SH-103, WEL50, W62-1).
• Confirm specs: check conduit/trade size, hub/thread size, conductor range, material and packaging quantity.
• Understand suffixes: suffixes often indicate finish or variant (flexible bail, iridited finish, etc.).
• Use datasheets: verify mechanical dimensions and tensile ratings before ordering replacements.

How Safsale helps buyers

• Organized listings and product filters for rapid selection.
• Multiple images and attribute fields to confirm fit on-site.
• Datasheets and catalog PDFs where available to verify conductor ranges and dimensions.
• Reviews and Q&A that highlight field experience and substitution notes.

Sourcing and replacement language

When placing orders, specify manufacturer, full catalog number, material and conduit/hub size (for example: "Thomas & Betts SH-103, 1 inch aluminum clamp-type service cap, pack of 10"). For wedge clamps, include the W-series catalog number and conductor range (for example: "Blackburn W62-1, #2–#6 range"). Always request the vendor datasheet or drawing to confirm fit and ratings.

Bottom line

Thomas & Betts and Blackburn remain commonly specified names for service entrance fittings, mechanical connectors and overhead wedge clamps. Procurement accuracy depends on confirming full catalog numbers, conductor ranges and datasheet dimensions; Safsale’s listings, images and PDFs are designed to support that verification. Safsale does not represent itself as an authorized distributor unless explicitly stated on a single product page.
