1/2"-1" Grounding Clamp

Mars 85374 – Grounding Clamp, 1/2" to 1" Pipe Range The Mars 85374 grounding clamp is engineered to provide secure bonding between copper grounding conductors and metal water pipes ranging from 1/2 inch to 1 inch in diameter. Constructed from corrosion-resistant materials, this clamp is suitable for use in residential, commercial, and industrial grounding systems. Features & Construction Details Application Range: Designed for bonding to rigid metal pipe from 1/2" to 1" OD Conductor Compatibility: Accepts solid or stranded copper wire used in typical grounding and bonding applications Material: Cast bronze body with plated steel hardware for durability in varied environments Mounting: Dual-screw clamping mechanism ensures stable mechanical connection to pipe surface Standards Compliance: UL listed for grounding and bonding in accordance with NEC Article 250 Product Specifications Pipe Size: 1/2" – 1" nominal diameter Conductor Capacity: Typically accommodates #14 to #4 AWG copper wire Connection Method: Mechanical screw terminal Body Material: Bronze alloy with stainless or galvanized fasteners Certifications: UL Listed for direct grounding and bonding applications Installation Notes Use this clamp in grounding electrode conductor (GEC) installations where bonding to metallic water service piping is required. For code-compliant installations, ensure conductor size and material match system requirements. The clamp should be torqued according to manufacturer guidance or as specified in NEC Table 250.122. Installation should be performed by a licensed electrical contractor to ensure compliance with national and local codes. Avoid installation on non-metallic piping or systems not intended to serve as grounding electrodes.
