Its ergonomic handles with rubber grips provide secure control, while the lifetime warranty guarantees long-term durability.

## Description

The 24 Inch Parallel Rule is primarily used for commercial purposes due to its extra long 24 inch acrylic construction, rigid chrome arms and handles. Parallel rulers are used to plot direction on nautical charts. Two straightedges are hinged so that they maintain the same angle. By alternating the moving edge, and securely holding down the non moving edge, you can move the rulers about the chart while still maintaining the same angle.

Very good quality accurate.. the rubber gives good grip but some times slipper when moving But over all very best

### ⭐⭐⭐⭐ Accurate but..
*by G***A on 7 April 2021*

This is a standard high quality product but it arrived with a a curve so when you glide it across the chart and wish to draw a straight long line, you might get an error of upto 2 degree high or low. I recommend buying a 20 inch.
