D2 Heat Inserts: Professional-Grade Defense Redefined

"Precision-engineered. Enforcement-grade. The heart of your ASP Defender system."

While most aerosol defense products are designed to be thrown away, ASP Defenders are built to a higher standard. The D2 Heat Insert is a precision-machined dispersion device crafted from aerospace aluminum and solid brass, incorporating a patented valve system designed for mission-critical reliability.

【Key Features】

1. Law Enforcement Strength: Our "Heat" formulation is maximum-strength OC, featuring 10% Oleoresin Capsicum and 1.4% major capsaicinoids. With a 2 million Scoville Heat Unit (SHU) rating, it delivers immediate and overwhelming stopping power.
2. NEW FOR 2024 — Invisible UV Dye: The latest Heat Inserts now include an invisible UV dye. This marks the assailant upon contact, providing law enforcement with a powerful tool for positive identification long after the encounter.
3. Precision Dispersion: Unlike cheap canisters, the ASP insert utilizes a specially-produced valve mechanism to ensure consistent delivery. Each 4-gram insert provides approximately twelve 1/2-second bursts with an effective range of five feet.
4. Aerospace Durability: The precision-machined aluminum body ensures the insert remains leak-proof and ready for action in any environment. Every insert is date-coded to guarantee reliability when it matters most.
5. Compatibility: Optimized for use in ASP Metro D2 and Sport D2 Defenders.
