With it's heavy duty construction, the Premium Dispenser stands up to wear and tear making it perfect for daily use. The new locking cradle locks the cartridge into position eliminating unwanted movement as well as preventing the cartridge from falling out. The push rod design features a stabilizer so the cartridge can be inserted face up or face down. The Premium Dispenser's superior design mechanics allow for an "easy squeeze trigger" making all of Vettec's products easier to dispense.
