The Wilcox Ratchet Strap Shroud (MICH/ACH) attaches to one hole or no hole helmet type, which do not require the inclusion or allow the addition of an added bolt; it uses front and rear hooks with a sleek and simple to use ratcheting mechanism to create increased tension to keep the helmet strap secure and in place. Incorporates high strength aluminum alloy aerospace material interface plates for extreme durability.
