This Kirby Morgan Head Cushion Foam Spacer (HCFS) Kit is intended or people with smaller sized heads or people who would like a tighter fit of their helmet(s) and oral nasal mask(s). It is a simple foam spacer that is placed into a standard head cushion. The spacer helps properly position the top and back of the head in the helmet by using a larger foam piece in the lower neck area which helps push the head forward and into the oral nasal mask.
This kit is used with KMDSI head cushion part numbers 510-682, 510-754 and 510-521.
