Slack Span Dead-end

A Slack Span Dead-end is a device specifically designed to terminate primary, secondary, and neutral conductors on aluminum-based conductors with diameter ranges from .229″ to 1.216″. The structure consists of a covered loop section with elastomer coating, and it’s made of galvanized steel or aluminum materials. Each Slack Span Dead-end is designed according to ANSI C37.4 standards and covers specific conductor diameter ranges.

The primary function of a Slack Span Dead-end is to provide secure termination while maintaining limited tension construction. It’s specifically designed to be installed on pin, line post, or spool insulators. The device features a unique design that eliminates bolts, nuts, and washers, making installation simpler. The maximum allowable loaded tension is 1000 lbs, though this is a practical limit rather than a holding strength rating.

Features of Slack Span Dead-end:
• Non-corrosive material construction
• Hot stick application compatibility
• Elastomer-covered loop for insulator protection
• Uniform conductor grip to prevent distortion
• Tool-free installation (except for hot stick applications)
• ANSI standards compliance
