Cable Gland Locknut · PG21 Thread · Flanged Polyamide Black · ITC Electrical 184.121
SKU: ITC-184.121
PG21 flanged polyamide locknut for securing compatible cable glands to panels and enclosures. The flanged profile provides a larger bearing surface that is commonly used to help seat the fitting against the panel cutout.
What this product is for
This PG21 flanged polyamide locknut is used to secure a compatible PG21 cable gland to a panel, enclosure, or equipment wall. It is a cable gland accessory for electrical and control installations where a plastic locknut is required.
Use for
Use for PG21 threaded cable glands installed through panels, junction boxes, control cabinets, and enclosures. Commonly selected where a non-metallic locknut is preferred and where the flange helps cover minor panel irregularities.
Avoid for
Avoid for thread types other than PG21, or where a metal bonding or EMC locknut is required. Do not use as a substitute for a sealing washer where the installation needs additional environmental sealing.
Best for
Best for industrial and commercial panel work using compatible PG21 cable glands. The flanged design is typically chosen over a non-flanged locknut when you want a larger contact surface on the inside of the enclosure.
Installed in
Typically installed inside electrical enclosures, control panels, terminal boxes, and machine cabinets after the cable gland is inserted through the knockout or drilled opening.
Why this product exists
This locknut provides the mechanical retention needed to hold a PG21 cable gland in place. A flanged plastic locknut can help distribute clamping force over a wider area. Sealing performance depends on the gland, panel condition, and whether a sealing washer is used.
Compared with similar products
Compared with a non-flanged PG21 locknut, this flanged version offers a larger contact surface. Compared with brass locknuts, polyamide locknuts are commonly chosen where a non-metallic accessory is preferred. Actual suitability depends on the gland type, enclosure material, and application requirements.
