The HRF Concepts HUNCHBACK, based off the original RAMP, is designed to be seated directly behind the aluminum ModButton and provide an ergonomic and discernable activation method for ModButton Lite switches.*

Utilizing the same rail grabber design as the original, the HUNCHBACK positions the Button at a reduced 13.5 degree angle while taking up the same footprint as a normal ModButton Lite.

The HUNCHBACK, also referred to as the “Reduced Angle RAMP” previously, can be run separately from the aluminum ModButton or with a standard ModButton Lite.
