ASP Defender D1 HEAT Insert – 2 pk

The ASP Defender D1 HEAT Insert is the active OC cartridge for the ASP Metro Defender D1. This Insert is compatible with ASP Metro D1 Defenders and Sport D1 Defenders, and contains approximately six 1/2-second bursts.

Unlike common throwaway aerosol can defense products, ASP Defenders are highly-engineered dispersion devices that use a proprietary, replaceable OC (Oleoresin Capsicum) Insert. These Inserts are precision-machined from aerospace aluminum and solid brass, and incorporate a specially-produced valve system and patented dispensing mechanism.

The “Heat” formulation is maximum strength, law enforcement-grade OC: 10% Oleoresin Capsicum, 1.33% major capsaicinoids, two million Scoville Heat Units (SHU). We also offer Test Inserts, which contain a harmless, inert aerosol—we highly recommend them for practicing using your ASP Defender. Heat Inserts include invisible UV dye, to assist law enforcement in assailant identification.

NOTE: Heat Inserts are date-coded to assure reliability. After the date marked on the Insert, it should be disposed of in accordance with environmental regulations in your area.
