The Porcelain Mast Mounted Wire Holder, also called Mast Type Wireholder, secures and supports overhead service entrance lines, telephone cables, and electric fence connections to buildings or utility poles. The product features an adjustable service mast integrated with a porcelain insulator that provides a stable, non-conductive attachment point for electrical connections while preventing energy loss.
The holder combines galvanized heavy-duty steel with a glazed gray porcelain insulator. Steel components are hot-dip galvanized per ASTM (American Society for Testing and Materials) specification A153 for corrosion resistance. The reinforced design resists environmental factors including moisture and chemicals, with the galvanized steel reinforcement ensuring structural strength for secure wedge clamp attachment and long-term performance.
Installation uses a two-bolt clamp system for quick, flexible attachment to conduits without removing nuts. The holder mounts directly to utility poles or structures using included nuts, bolts, washers, or wood screws. Some models feature pre-assembled lag screws. Standard sizes accommodate service entrance masts from 1-1/4 inches to 3 inches in diameter, with larger models available for 3-inch to 4-inch pipes. The wire opening measures approximately 1 inch by 15/16 inches.
The product meets NRTL (Nationally Recognized Testing Laboratory) approval and complies with UL (Underwriters Laboratories) 514B standards for bonding and grounding, adhering to EEI (Edison Electric Institute) TD-24 industry standards for safe operation in electrical installations.
