Description

The 608 pins that come with the 21-E are insulated, except at the tips, and can reach a maximum penetration of 3-1/4″. This electrode is great for use on roofs, insulation, or EIFS. The 21-E is also available as the 21-E/001 with 6″” penetration, or as the 21-ET with a tapped handle for hard to reach areas.
