SINGER's extension table for its mechanical Heavy Duty machines snaps onto the free arm in place of the accessory storage box: it adds a 38.8 x 25.4 cm surface, with a ruler printed in inches and centimetres along the edge so you can measure without looking away from the work. Folding legs keep it level and tuck away for storage.

It's built for the mechanical Heavy Duty models made since fall 2019 — the 44S, and the 4411, 4423, 4432, 4452, 5511 and 5523 from a specific serial number onward — not for the Heavy Duty 4511, 4523, 4532 and 4552, which the manufacturer explicitly excludes.

Pros and cons

In favour

It snaps onto the free arm with no tools, in place of the accessory storage box source
Folding legs keep it level and tuck away for storage
The ruler printed in inches and centimetres along the edge means you don't need a separate tape measure source

Worth knowing

It's not compatible with the Heavy Duty 4511, 4523, 4532 and 4552: the manufacturer explicitly excludes them source
On the 4411, 4423, 4432, 4452, 5511 and 5523, the serial number needs checking: below a certain threshold it won't fit source
