HANS Device Model Terminology

[rcl4668]

I just picked up a used but recertified HANS device from a former racer in my area. It fits my neck and the seatback angle of the Viper. The HANS is made by Hubbard/Downing, Inc. and has the model designation "20RP". I know 20 refers to the seatback angle but does anyone know what the RP stands for? Thanks.

Spoke with them today and the 20RP is an older model designation for 20M or 20 degree seatback angle, Medium neck size.
