Worksafe Heat 4For general engineering work where hot substances may be present, we have developed Worksafe Heat 4. This is not intended for welding work, but is well suited for handling in connection with this. Fully lined with soft cotton flannel, and therefore has the same heat properties as the thicker welding gloves. The collar is shorter, which makes the glove more supple and comfortable. Suitable for: Handling of hot objects, assembly, workshop and crafts.
