Use this trigger sprayer with compatible anti back-off bottles to create a complete "safe-lock" system. The "safe-lock" system ensures that the trigger sprayer will not loosen from the bottle for safe, reliable performance. A textured grip and ergonomic shape help reduce fatigue for comfortable use during extended cleaning periods. Mist setting evenly covers a wide area to effectively apply liquid to large surfaces. Anti back-off system will not become disengaged when used with the Impact Products 24 oz. graduated bottle with anti back-off or 32 oz. graduated bottle with anti back-off (each sold separately). The tube length is 8-1/8".
