Ground Clamp · 1-1/4 in to 2 in conduit or pipe · Brass body with stainless steel screws · Nesco 626B

What this product is for

The Nesco 626B is a brass ground clamp used to make a grounding or bonding connection to 1-1/4 in to 2 in conduit or pipe. It is suited to electrical grounding work where a mechanical clamp is specified and a secure metal-to-metal connection is needed.

Use for

Use for grounding and bonding on compatible conduit or pipe sizes from 1-1/4 in to 2 in (approximately 32 mm to 51 mm). Common applications include service grounding, bonding upgrades, retrofit work, and maintenance in residential and light commercial installations.

Avoid for

Avoid using this clamp on sizes outside the listed range or where the installation requires a different grounding connector type, direct burial rating, lay-in style, or a connector specifically listed for rebar or ground rod use. Always match the connector to the conductor, substrate, and local code requirement.

Best for

Best for electricians and contractors who need a simple brass clamp for pipe or conduit bonding in the 1-1/4 in to 2 in range. The brass body supports conductivity and corrosion resistance, while stainless steel screws help in damp or service environments.

Installed in

Typically installed on metal conduit or pipe in electrical rooms, service areas, commercial tenant spaces, residential service upgrades, and maintenance projects. Final suitability depends on the exact pipe material, conductor size, and approval required by the authority having jurisdiction.

Why this product exists

This clamp provides a practical way to bond or ground to larger conduit or pipe sizes without changing the raceway layout. It is commonly selected when a field-installed mechanical connection is faster than replacing fittings or adding alternate bonding hardware.

Compared with similar products

Compared with smaller ground clamps, this model fits larger 1-1/4 in to 2 in trade sizes. Compared with bronze or direct burial clamps, this listing is best treated as a standard brass mechanical ground clamp unless the project documents call for a burial-rated connector. As a rule of thumb, always confirm conductor range and listing details before ordering for inspection-sensitive work.

Typical guidance only: actual suitability depends on conductor type, installation conditions, and local electrical code.
