This lug provides a secure mechanical and electrical connection when properly crimped, suitable for use in switchgear, panelboards, motor control centers, and power distribution equipment. The tin-plated copper construction resists oxidation, while the integrated sight window allows visual confirmation of full conductor insertion before crimping. The green color code provides quick wire size identification during installation and inspection.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWire Size: 1 AWG\u003c\/li\u003e\n\u003cli\u003eStud Size: 5\/16\"\u003c\/li\u003e\n\u003cli\u003eConfiguration: 1-hole\u003c\/li\u003e\n\u003cli\u003eBarrel Type: Standard (short barrel)\u003c\/li\u003e\n\u003cli\u003eMaterial: Tin-plated copper\u003c\/li\u003e\n\u003cli\u003eColor Code: Green\u003c\/li\u003e\n\u003cli\u003eOverall Length (L): 43.9mm (1.72\")\u003c\/li\u003e\n\u003cli\u003eLength 1 (L1): 19.1mm (0.75\")\u003c\/li\u003e\n\u003cli\u003eDiameter (D): 16.8mm (0.66\")\u003c\/li\u003e\n\u003cli\u003eDiameter 1 (D1): 11.7mm (0.46\")\u003c\/li\u003e\n\u003cli\u003eDiameter 2 (D2): 9.1mm (0.35\")\u003c\/li\u003e\n\u003cli\u003eWidth (B): 20.3mm (0.80\")\u003c\/li\u003e\n\u003cli\u003eWidth 1 (E): 8.8mm (0.40\")\u003c\/li\u003e\n\u003cli\u003eThickness (F): 2.5mm (0.10\")\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: 90°C\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 35 kV\u003c\/li\u003e\n\u003cli\u003eMaximum Amp Rating: 130A\u003c\/li\u003e\n\u003cli\u003eFeatures: Sight window for conductor visibility\u003c\/li\u003e\n\u003cli\u003eCertifications: UL approved, CE certified, RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCross-Reference\u003c\/h3\u003e\n\u003cp\u003eThis 1 AWG short-barrel compression lug with 5\/16\" stud hole is equivalent in form and function to standard one-hole copper lugs offered by major manufacturers including Burndy, Panduit, and Ilsco.
