Heavy Duty Boost Cable Clamp 800 A

This Westward 23PC40 clamp set delivers heavy duty battery connections for 12 V and 24 V systems. Two parrot jaw clamps in red and black accept 1 to 4 AWG cable and carry up to 500 A. Steel contacts with vinyl insulation provide secure grip on terminals up to 4 1/4 in opening.

Suits 12 V and 24 V battery maintenance

Technicians needing reliable jump start or charging clamps for standard automotive voltages will find the 500 A rating and wide jaw opening practical. Buyers who require higher continuous current or different voltage ranges should look at other solutions.

Simple screw on installation

Each clamp fastens to the cable with an included lead jaw and screw, so no special tools are needed. Ensure the screw is fully tightened and the vinyl insulation seats cleanly to avoid loose contact or overheating during use.

Questions about this item

What cable gauge do I need to match the 1 to 4 AWG range of these clamps?

Use battery cables sized between 1 AWG and 4 AWG so the screw terminals grip securely and carry up to 500 A.

Will the 4 1/4 in jaw opening fit the terminals on my older 12 V or 24 V battery?

Yes, the parrot-jaw design opens to 4 1/4 in, accommodating standard post and stud terminals found on 12 V and 24 V systems.

How can I verify the red and black clamps are making solid contact after I tighten the screws?

Check that each vinyl-insulated handle shows no gap at the jaw, then confirm continuity with a multimeter across the steel contact faces.
