Projecta BT21-1 Split Barrel Brass Battery Terminal, Single

Quick answer

The Projecta BT21-1 is the Split Barrel Brass Battery Terminal, Single. One universal split barrel terminal in a blister pack, the BT21-1 is the one to grab when a single clamp has corroded or cracked on either post.

Main cable range is 50 to 70 mm², 0 to 00 B and S.

Fit the cable into the split barrel and solder or crimp it, whichever your shop prefers. Projecta electroplates these brass terminals with a nickel coating.

Listed as universal, so it is not tied to the positive or negative side. Clean the post back to bright metal before fitting, and coat the joint once tightened.

Check the terminal again after the first week, as new cable can settle under the clamp. After fitting, a thin smear of terminal grease or spray protector slows corrosion. Tighten firmly but do not crush the post; a lead post deforms easily. Keep the positive covered so a spanner cannot bridge it to the body. Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly.
