• Ground Bonding Connector with Pigtail Access Hole​ – Designed for #10–#14 copper grounding splices in outlet boxes, light fixtures, and panel grounds. Open-top hole fits a grounding pigtail loop and gives probe access for continuity checks without unthreading. Not a general-purpose splice nut—for grounding conductors only.
• Winged Body for Hand-Torque in Tight Boxes​ – Ergonomic wings give leverage so you can snug a secure bond without linesman pliers behind a flush-mounted receptacle or cramped ceiling box. Spring-steel insert bites the conductors and holds through thermal cycling.
• 221°F Flame-Retardant Shell​ – Thermoplastic rated to 221°F (105°C), 600V building wire / 1000V lighting circuits. Steel spring is corrosion-resistant for attic heat, crawlspace damp, and garage shop conditions where standard nylon nuts can brittle-crack.
• Secure Bond, No Loose Pigtail Wander​ – Pre-wrapped square spring engages strands from four sides so the ground pigtail won't back out if the bundle gets nudged during device-mounting. Holds through vibration from ceiling fans and attic exhausts.
• 50-Pack for Remodel or Van Restock​ – One jar covers outlets + switches + fixtures on a typical 3-bed/2-bath remodel, or tops off the van's consumables. Licensed electricians, apprentices, and DIYers doing ground-bonding work—alternative to the big-box brand jar at a saner price.
