Overview
A homeowner or handyman with a few tubes of medium viscosity caulk can use this Newborn gun, which has a steel half-barrel cradle and a spring. Its ratchet rod has teeth that grip and hold the rod between squeezes.
The reason to buy is a simple, light cartridge gun with a ratchet that cuts drips on ordinary sealing jobs. The limitation is the low thrust ratio and the sparse listing, which gives no surface list, cutter details or warranty.
Who it's for
Occasional DIY sealing around tubs, windows and trim. Daily users and anyone with thick adhesive will want a smooth rod gun with a higher thrust ratio and a built-in cutter.
Pros and cons
- Steel half-barrel frame
- Teeth in the rod hold position
- Light item weight
- Fits standard cartridge size
- Low thrust ratio
- No built-in cutter listed
- Ratchet action is louder
- Warranty not stated
Performance notes
The rod teeth catch after each pull of the trigger so pressure is held and drips are minimized. Low thrust means the squeeze needed rises quickly with thicker material, which is why it is matched to medium viscosity products.

Frequently asked questions
How do I load a cartridge in the Newborn 189D?
The listing gives no loading steps. It is a half-barrel cradle gun for 1/10 gallon cartridges, so the cartridge rests in the cradle with the ratchet rod behind it.
What is the difference between a ratchet rod and a smooth rod?
The description says the ratchet rod has teeth that hold position after each pull to minimize drips. Smooth rod guns are a separate type.
Does the Newborn 189D handle thick adhesives?
The listing recommends it for medium viscosity materials with a 6:1 thrust ratio, so very thick adhesives are not what it targets.
