Mark III/IV Chemical Holder

The Mark III/IV Chemical Holder by Boston Leather is a purpose-built tactical accessory designed for law enforcement and military personnel who carry chemical defense agents, riot control devices, or small aerosol equipment as part of their duty load. This compact carrier solves the real-world problem of secure, accessible storage for chemical spray canisters on the duty belt—keeping essential self-defense tools within quick reach without adding bulk or compromising belt real estate. Whether you're a patrol officer, tactical operator, or security professional, this holder ensures your chemical agent remains protected and ready for deployment.

Constructed from top-grain leather, the Mark III/IV Chemical Holder delivers the durability and retention needed for daily law enforcement wear. The snap closure provides positive retention—fast enough for emergency access yet secure enough to prevent accidental deployment during vehicle entries, climbing, or ground operations. Boston Leather's top-grain construction resists sweat, UV degradation, and routine abrasion far better than split leather alternatives, ensuring the holder maintains structural integrity and aesthetic appearance through years of active duty use. The compact 9.45 x 2.55 x 6.75-inch profile fits standard duty belts without excessive protrusion, and the lightweight 0.18 lbs design means minimal load fatigue during extended shifts.

This holder is ideal for officers carrying OC spray, CS canisters, or similar aerosol devices on 1.75-inch duty belts using standard duty gear configurations. The Mark III/IV designation indicates compatibility with both Mark III and Mark IV chemical canister profiles, making it a versatile choice for departments using multiple spray models or for individuals upgrading equipment. Installation is straightforward via belt loop attachment to any standard duty rig. Law enforcement agencies and tactical teams favor Boston Leather products for their proven reliability in high-stress environments—this chemical holder maintains that reputation with consistent snap retention and leather longevity that outlasts cheaper alternatives.
