The Fieldpiece ASLS2 Straight Tip Silicone Test Lead Set features silicone-isolated high copper strands. The ASLS2 offers basket-style strain relief and fit inside the test lead holders on all Fieldpiece Meters that have built-in holders. The ASLS2 test leads are rugged and stand up to high and low temperatures better than traditional vinyl test leads. These test leads avoid becoming brittle in extremely cold temperatures.
