The ASP D1 Defender Test (Inert) Insert Twin Pak (ASP part no. 54913) is a two-pack of inert practice inserts for the Metro D1 and Sport D1 Defenders. ASP sold it earlier as the Palm Defender test insert. The aerosol inside is harmless, so you can run through the safety release and activation as many times as you need without exposing anyone to OC. Practicing with your own Defender before carrying it loaded is exactly what ASP recommends these inserts for.

Key Specifications

• The insert is compatible with Metro D1 and Sport D1 Defenders, the two ASP models that use this size.
• The pack contains two Test inserts, so you can practice with one and keep the other in reserve.
• The contents are a harmless inert aerosol, which makes the insert safe for practice and function testing.
• Each insert holds approximately six half-second bursts, enough to practice the activation sequence or cover a real discharge.
• Each insert is machined from aerospace aluminum and solid brass and has a specially produced valve system and patented dispensing mechanism.
• The inert Test insert is for training only and does not contain OC pepper spray, so keep a Heat insert for carry.
