HS   -   Heavy Density Criss Cross Silicon Carbide

Description: 8-pound-per-cubic-foot density bullet shaped foam cylinder with 90 Shore A durometer urethane coating in double-spiral configuration and carbide straps.

Design Function: Heavy scraping.  For hard scraping scales (harder than 6 on Moh's scale of hardness).

Alternate Function: Good when used in line conditions that would shorten the life of the criss cross, or when scraping is needed, but wirebrush is too much.
