PRODUCT SHORT DESCRIPTION
Insulated stringing pulley set with 2T double-wheel, single-wheel and 3T triple-wheel blocks for live-line and cable-pulling work. Fiberglass-insulated frames, smooth sheaves.

PRODUCT DESCRIPTION

The insulated stringing pulley block set is used for hoisting and pulling conductors and tools on overhead lines, including live-line work where the supporting rope or block must provide electrical isolation. The blocks combine high-strength nylon or aluminum sheaves with fiberglass-insulated side plates and hooks, breaking the conductive path between the load and the structure. The range includes single-wheel, 2-ton double-wheel and 3-ton triple-wheel configurations to match different lifting and stringing loads, giving line crews a versatile, safe pulley system for construction and maintenance.

Key Features
• Electrical Isolation — Fiberglass-insulated frames and hooks break the conductive path for live-line safety.
• Single / Double / Triple Wheels — Choose single-wheel, 2T double-wheel or 3T triple-wheel blocks for the load.
• High Load Ratings — 2-ton and 3-ton versions handle heavier conductors and tool-string pulls.
• Smooth Sheaves — Low-friction nylon or aluminum wheels reduce rope wear and pulling effort.
• Strong Hook Latches — Self-closing safety hooks prevent the rope or anchor from disengaging.
• Lightweight Build — Insulated composite and aluminum components stay easy to handle at height.
• Weather Resistant — Non-rusting sheaves and plated hardware suit outdoor line work.
• Set Versatility — A matched set covers most stringing, hoisting and rescue-pull scenarios.
