The Allied Bolt Tap Clamp (vendor part 897, Millennium part 575133) bonds a #2-10 AWG ground wire to 1/4 in to 7/16 in strand for grounding and bonding work on aerial builds, boxed 50 to a carton. Aluminum construction resists corrosion in outdoor bonding runs, and removable center plates let linemen install it midline at non-terminal points on the strand without cutting it. It's a standard part of grounding a messenger strand along a fiber or telecom pole line. Millennium stocks it with suspension clamps, ground rods and bonding hardware for a full grounding kit.
