An assembly for fixing cross-wires and pull-offs to the trolleybus contact wires. It consists of two yokes, two ZPV contact wire clamps and an I-1,7 "large"-type insulator. The insulator is made of moulded impregnated wood also known as delta-wood.

This assembly can have any model of "long"-type insulators but the one in the picture is the most common complectation (it's used country-wide exept for Moscow and St. Petersburg where only fiberglass silicone-coated insulators are used).
