Screw-type wire holders organize and secure electrical wiring in residential, commercial, and utility applications. They attach to surfaces such as wood poles or walls via a screw mechanism, serving as mounting points for bail wires of service wedge clamps.
The holders feature heavy-duty construction with a lag screw for robust mounting. Key design elements include a self-drilling screw with a type ’17’ point for rapid wall installation that reduces wood splitting risk, adjustable clamp pressure to accommodate different cable thicknesses, a snap-lock mechanism for secure wire retention, and multi-directional mounting capability for versatile installation angles. Installation requires only a 5/8-inch speed wrench or compatible bits such as a #14-18 slotted bit or #3 Phillips bit.
The holder body uses Nylon Alloy, which is Ultraviolet (UV) resistant to prevent sunlight degradation. The screw component is Hot Dip Galvanized per American Society for Testing and Materials (ASTM) Specification A153 for corrosion resistance, with optional galvanized steel reinforcements for enhanced outdoor durability. Specifications include a 3-inch screw length with #18 wood screw thread, accommodating wire diameters from approximately 6mm to 25mm.
The product meets Underwriters Laboratories (UL) 514B standards for bonding and grounding and carries Nationally Recognized Testing Laboratory (NRTL) approval for electrical installations. Standard packaging includes 50 units per carton, with pallet quantities up to 9000.
