BORG 4571 M42EXTENSION Barrel LBK
BORG 4571 M42EXTENSION Barrel LBK | A clearly named extension barrel
BORG 4571 M42EXTENSION Barrel LBK is identified by its name as an M42 extension barrel, for photographers and optical-system builders who already know they need this specific kind of component. The title gives you three useful identifiers to work from: BORG, 4571 and M42EXTENSION Barrel LBK. That makes it easier to match the item you’re looking for by its named series and type, rather than choosing by appearance alone. Its place is in a setup where an extension barrel is the part required; it isn’t described as a complete lens. If you’re comparing components for a planned build, use the full product name when checking your parts list, particularly the 4571 model reference and the M42EXTENSION designation. The available product information is brief, so this page sticks to what the name establishes instead of guessing at dimensions or fit. It’s a focused listing for someone who has a specific barrel in mind.
Specialist Note
This is a straightforward part to identify by name: M42EXTENSION says you’re looking at an extension barrel, while 4571 gives you the specific BORG reference to match against your plan. I’d treat those two details as the useful starting point when organising a build, rather than assuming a barrel with a similar-looking name will do the same job. It suits someone assembling a setup around a known component requirement. Keep the full title with your parts notes, and use it when you’re selecting the item for that role. The listing establishes the type and reference, not a particular measurement or pairing, so I wouldn’t infer those from the name.
