Abstract

An inclinometer 20 includes a module 22 which is mounted to a rail 32. The rail 32 has a hollow I-shaped cross-section which affords substantial resistance to torsional and bending loads about the longitudinal axis 34 of the inclinometer 20. The rail 32 and in particular a first end 36 of the I-shaped cross-section includes first and second curves 48, 50 which define lobes which provide a rail design more suitable for gripping and placement by the user.
