The Slack Span Dead End terminates primary, secondary, and neutral conductors on aluminum-based systems, accommodating conductor diameters from 0.229 to 1.216 inches. This ANSI-compliant device serves overhead transmission and distribution lines in limited tension applications, with a practical use limit of 1000 pounds maximum allowable loaded tension based on utility safety practices.
Tool-free installation simplifies deployment except in hot stick applications. The design eliminates bolts, nuts, and washers while providing uniform conductor grip to prevent distortion. Available in galvanized steel or aluminum construction for corrosion resistance, the device features an elastomer-covered loop that protects against abrasion, prevents insulator glaze damage, and minimizes Radio Frequency Interference (RFI) and Television Interference (TVI). The elastomer formulation resists ozone attack and weathering.
Compatible with Aluminum Conductor Steel Reinforced (ACSR), All Aluminum Conductor (AAC), and All Aluminum Alloy Conductor (AAAC) types, the device installs on American National Standards Institute (ANSI) C, F, and J neck pin, line post, or spool insulators with minimum groove widths of 9/16 inches. Multiple models identified by catalog numbers and color codes correspond to specific conductor diameter ranges. This precision device requires trained personnel for installation and is designed for single use, though reapplication is permitted twice within 90 days of initial installation.

Frequently Asked Questions
What is a Slack Span Dead End?
A Slack Span Dead End is a device designed to terminate primary, secondary, and neutral conductors on aluminum-based conductors with diameter ranges from .229 to 1.216 . It provides secure termination in limited tension construction where guying restrictions prevent full tension spans, with a maximum allowable loaded tension of 1000 lbs.
What are the key features of this product?
Key features include tool-free installation (except for hot stick applications), a unique design that eliminates bolts, nuts, and washers, uniform conductor grip to prevent distortion, non-corrosive materials (galvanized steel or aluminum), a covered loop with elastomer for abrasion protection that minimizes RFI (RIV) and TVI, and compliance with ANSI standards for use on pin, line post, or spool insulators.
What types of conductors can it be used with?
It is intended for aluminum-based conductors including ACSR, AAC, and AAAC types with diameter ranges from .229 to 1.216 . Each unit covers a specific range of conductor diameters and should only be used on the size and type for which it is designed.
How do you install a Slack Span Dead End?
No tools are required for installation, except for hot stick applications. It can be installed on pin, line post, or spool insulators in limited tension construction. The dead end is compatible with ANSI C, F, and J neck insulators or non-insulator fittings with smoothly contoured dimensions, a seat diameter consistent with insulator necks, and a minimum groove width of 9/16 .
Can I order these in bulk, and what size ranges are available?
Units are typically packaged in cartons of 25 and available in various catalog numbers covering conductor diameter ranges from .229 to 1.216 , allowing you to stock multiple sizes for large-scale project requirements.
