Aluminium safety rule
This 300mm/12” aluminium rule has a shallow indentation to keep fingers firm and safe on the rule when marking or cutting.
Metric (cm and mm graduations) on one side, imperial (inches, half-, quarter- eighth- and sixteenth-inch graduations).
For increased security please see TR10036 (deeper indentation and rubber, non-slip strips on the reverse). Steel safety rule TR10009 is more resistant to being damaged by repeated blade use.
