300 mm adjustable square ruler

This 300 mm square ruler adjusts to 45 and 90 degree angles for layout and checking work. A built-in bubble level adds a quick reference for horizontal or vertical alignment. It suits hobbyists, woodworkers and metalworkers who need a compact combination tool.

Integrated bubble level

The vial lets you confirm level without reaching for a separate spirit level. Adjustable arms lock at the two preset angles to speed repetitive marking tasks. Buyers who need continuous angle settings or longer reach will need a different instrument.

Questions about this item

Will the bubble level need recalibration or replacement over time?

The bubble level is a sealed vial with no user-serviceable parts; if the fluid clouds or the bubble sticks, the whole ruler must be replaced.

What limits accuracy when the ruler is used continuously on a job site?

Repeated sliding of the adjustable arm can loosen the locking mechanism, so the 45 and 90 degree stops may drift before the scale wears.
