Single-arm lugs of types U1 and U1K are designed to connect the rod of a suspension insulator or shackle to other line fittings. The spherical joint socket of the lugs is manufactured in accordance with GOST 27396-93, and the connecting dimensions of the eye comply with GOST 11359-75. To secure the insulator rod or shackle pin in the lug socket, W-shaped locks are used.

The lugs are available in two versions:

• U1 — standard single-arm lugs.
• U1K — shortened single-arm lugs intended for assembling insulating suspensions without protective fittings, allowing for reduced length and weight of the suspension.

The products are manufactured according to TU 3449-001-52819896-2010.
