How it connects
The rigid cylindrical cartridge tube drops into the open half-barrel cradle with its nozzle extending through a front U-notch, while an axial disc plunger advances into the open cartridge rear against the internal sliding piston.
Male and female halves
The dispenser cradle and plunger act as a female-receptive cradle and male driving piston, mating with the cylindrical body, front shoulder, and internal cup piston of the disposable cartridge.
Usually connects to
- Standard 1/10 gallon (10 oz / 300 ml / 310 ml) caulk and adhesive cartridges (e.g. Simpson Strong-Tie AT-3G, standard silicone/acrylic tubes)
Common sizes
- Sized for cartridges approx. 48–51 mm (1.9–2.0 in) in outer diameter and 215–220 mm (8.5–9 in) body length.

How to recognise it
Recognizable as a half-cylindrical or skeleton steel/composite carriage roughly 9 inches (220–230 mm) long with an arched front collar featuring a U-shaped slot for the threaded spout/nozzle, accompanied by a rear-advancing circular pusher disc roughly 45–48 mm in diameter.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| 29 oz / quart cartridge cradle | 29 oz caulk gun cradles are much longer (approx. 13–14 inches / 350 mm) and wider (around 2.5–3 inches diameter) compared to 10 oz cradles. |
| Dual-component coaxial / side-by-side dispenser cradle | Dual-component dispensers use dual plungers or dedicated coaxial drive plates rather than a single 50 mm axial plunger disc. |

Good to know
Commonly designated for 1/10 gallon (often marked as 9.5 oz, 10 oz, or 10.5 oz in North America, and 290 ml, 300 ml, or 310 ml in Europe and Asia). The interface holds the cartridge mechanically and transmits axial dispensing thrust.
