Penn Union Stackable Lugs — BBLS Series (Long-Barrel, Two-Hole)

Penn Union BBLS stackable copper compression lugs are long-barrel, two-hole connectors with a closed transition for reliable terminations on switchgear, panelboards, and bus bars. They’re manufactured from high-conductivity seamless copper tubing and electro-tin plated to minimize contact resistance and improve corrosion performance. Stackable design and an offset tongue align with compatible bottom-stacking lugs so multiple conductors can be terminated to a common surface.

Key Features

• • Long-barrel, two-hole stacking lugs with closed transition (protects cable end and supports sealing)
• • Seamless high-conductivity copper; electro-tin plated for low resistance and corrosion protection
• • Offset design aligns with BBLB bottom-stacking lugs for multi-conductor terminations
• • Color-coded barrels with die index markings for correct tool/die selection
• • Medium-voltage use up to 35 kV (per catalog guidance)
• • UL 486A-B listings for power (range dependent) and UL 467 listings for grounding/bonding/direct burial (range dependent)
• • Compatible with Penn-Union, Burndy, Huskie, T&B, and Versa-Crimp® style tooling
