Catalog version: 2026-10-20

Sizes: see table below
- Two halves that clamp the hot spool's tube with their lids (2 × M4 × 20) just above the fins and hang round them, open at the bottom: the torch or burner below fires up into it, the gas leaves through six windows under the lid.
- It touches only the tube at the lid. The heat source is the builder's choice: a propane or butane torch head in the torch stand, or a small gas burner firing into the open bottom.
