This specification covers the material,
requirements, examinations, tests and packaging for a
family of blow molded plastic divider racks used for restraining loose: unpalletized 155mm projectiles; unpalletized 8 inch projectiles; or unpalletized, unboxed 120mm mortar rounds contained in fiber tubes during on-vehicle storage and transport(see 6.1).
The rack consists of specifically designed plastic dividers that, when assembled, will restrain any conventional projectiles of the 155mm or 8 inch family, or all 120mm mortar rounds in fiber tubes(see 6.4). The loaded racks are restrained in a tactical transport
vehicle by means of a cargo tiedown strap(s) applied in an approved manner. The combinations for 155mm or 8 inch are referred to as Loose Projectile Restraint System(LPRS). The combination for 120mm mortar is referred to as Loose Round Restraint System(LRRS).
