1/4" VDE Insulated Socket Extension Bar ALYCO, 100mm or 150mm. With 1000V AC and 1500V DC protection.

The ergonomic bi-material handle allows maximum force to be applied without tiring the hand, even in intensive repetitive tightening. The square drive's spring-loaded ball fits into a recess in the socket to prevent it accidentally falling off and to keep the other hand free.
