Model Number : 188
The Newborn 188 Super Ratchet Rod Cradle caulking gun has a steel half-barrel frame that fits 1/10-gal. cartridges and has a 6:1 thrust ratio for use with medium viscosity materials such as silicone. The ratchet-style pressure rod has teeth that hold the rod in place after each pull of the trigger. For thinner materials, this helps minimize drips.
