Grounding Locknut with Lug · 1-1/2 in Trade Size · Zinc Die Cast · Bridgeport 165-G

SKU: MC-LK1.5GZ

1-1/2 in grounding locknut with tin-plated aluminium lug for bonding threaded connectors or nipples to a box or enclosure. Commonly used where space is tight and a grounding bushing plus standard locknut would take more room.

What this product is for

This grounding locknut is used to fasten threaded conduit fittings, connectors, or nipples to a box or enclosure while adding a bonding or grounding connection through the attached lug.

Use for

Use for 1-1/2 in trade size rigid conduit or threaded fittings where you need a compact bonding method inside an enclosure. It is commonly used in commercial and industrial panels, pull boxes, and equipment enclosures.

Avoid for

Avoid using it where a standard non-grounding locknut is specified, or where the fitting and enclosure arrangement does not require a bonding lug. Confirm conductor range and installation method before ordering.

Best for

Best for tight box locations or fittings with shorter locknut threads, where replacing a separate grounding bushing and locknut can simplify the connection.

Installed in

Installed in steel boxes, cabinets, troughs, and other metallic enclosures with 1-1/2 in threaded entries. Approximate body size from distributor data is about 2.56 in wide x 0.68 in high (65 mm x 17 mm).

Why this product exists

It provides a grounding point directly at the locknut location, helping electricians bond fittings inside the box without adding extra hardware. This can help in tight layouts and service work where thread length is limited.

Compared with similar products

Compared with a standard locknut, this version adds a lug for bonding. Compared with using a separate grounding bushing and locknut, it is typically more compact. Actual suitability depends on the fitting, conductor size, enclosure layout, and local electrical code.
