- Steel half-barrel (also called cradle) frame caulking gun for 1/10-gal. cartridges
- Thrust ratio of 6:1 for use with high viscosity materials
- Ratchet-style pressure rod has teeth to hold the rod in place after each pull of the trigger for minimizing drips
- Zinc chromate plating offers good corrosion resistance
- Welded plate in back for securing cartridge in place
The Newborn 307 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 high viscosity materials such as acrylic, adhesives,
asphalt, butyl, and cement. 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. The zinc chromate plating offers
good corrosion resistance. A seal puncture tool and a spout cutter are
built into the side of gun for opening cartridges without a knife, and a
wrist strap allows the gun to be held more securely. The hook on the
back allows it to hang on a ladder.
Caulking guns, also called
caulk or cartridge guns, dispense a controlled flow of products such as
caulk, sealants, and adhesives from a tube or cartridge. A manual
caulking gun consists of a frame which holds the tube, a trigger, and a
rod which moves forward when the trigger is depressed, dispensing the
product. Manual caulking guns have a thrust ratio; the higher the thrust
ratio, the easier it is to dispense the caulk, sealant, or adhesive.
Air-powered or pneumatic caulking guns also have a frame and a trigger,
but are used with an air pressure regulator that pushes the product from
the tube using air pressure instead of a rod.
