Use the Contour Trigger Sprayer with compatible, anti-backoff bottles (Impact 32 oz. 5032AB or 24 oz. 5024AB) to create a complete "safe-lock" system. Stem measure 9-1/2" from the end of the thread to foot. This complete system ensures that the trigger sprayer will not unloosen from the bottle. Wide trigger and ergonomic shape are designed for your comfort. Textured grip allows a secure hold. Chemical-resistant trigger sprayer delivers a high output with an adjustable tip from spray to stream. It primes in four to five strokes. With the no-leak design, plastic sprayer can be used as a reshipper.
