Blocks are carefully designed to secure the best possible combustion results with the various nozzles used with them.

Block holders are cast iron boxes into which the blocks are cemented.

The holders are faced smooth and drilled with bolt holes to accommodate various burner cages.

Each assembly includes 4 bolts to hold cage if field installation is being made.

Complete assemblies of cages, blocks and holders are listed as Atmospheric Torch Burners, and Blast Torch Burners.
