Square U-Shape 200×200 (sides 200 mm), ideally suited as a table extension, for vertical setups, as well as a sturdy connection between two welding tables. Riser Blocks are mounted to the table using connector bolts (Item No. 280560.N).

When used as a table extension exceeding 1000 mm, the Riser Block has to be supported by a table leg.

Combined with the legs (Item No. 280371), Riser Blocks can be flexibly used on the foundation rails.

A multitude of clamping- and combination options with other squares and stops are facilitated by the five-sided boreholes and the optional diagonal hole arrangement.

The 100×100 mm grid simplifies orientation.

From a length of 500 mm all U-shaped squares have mounting holes on the back to attach table legs (except 280310.P).
