With our high-quality connecting elements - corner connectors, U blocks and Double countersunk locking bolt - you can extend your welding table quickly, safely and accurately. The sophisticated design and precise perforations enable flexible constructions, such as 45° extensions or the connection of several tables to form a stable overall system.
The U blocks in particular is ideal as a table extension or base for frame and vertical structures. From a length of 1 m, an additional foot ensures maximum stability. The countersunk locking bolt with countersunk hexagon socket guarantees a permanent, solid screw connection for heavy elements such as tables, angle brackets and blocks- exclusively in system drill holes for maximum safety.
This creates the optimum basis for precise work, maximum load capacity and a durable extension to your HISWeld welding table system.
