When you're digging snow pits and documenting layers you need a ruler that won't roll up or bend on you, but can be stored in a small space. Our folding rulers, in 100cm and 200cm lengths are perfect for outdoor use. The 100cm model folds down to a mere 5” (12.1 cm) in length and each section snaps to 90° right angles, or in-line.
Expanded length: 39.5" (100 cm)
Collapsed size: 5" x ½" x ¾" (12.7 x 1.3 x 1.9 cm)
