The BLACK+DECKER 330mm Steel Caulking Gun is a straightforward, no-nonsense manual caulk gun you’ll grab day in and day out on the job site — no batteries, no fuss, just solid mechanical action you can trust for sealing and gap-filling jobs. It’s built with a steel half-open frame that holds standard 330 mm cartridges without twisting or flexing under load, so you get predictable performance every time.

What really matters when you’re working long hours is comfort and control — and this gun delivers with its bi-material handle that feels good in your hand and helps keep fatigue down when you’re pushing heavy sealants into joints or cracks. The mechanism itself is smooth enough that you’re not wrestling the tool just to get a bead flowing.

Key Features:

• Steel Half-Open Frame - Holds standard cartridges firmly and resists bending when you’re applying pressure.
• Smooth Pressure Rod - Lets you dispense material with less force and less chatter than ratchet-style guns.
• Bi-Material Handle - Gives you grip and comfort for longer caulking runs without hand strain.
• Standard Cartridge Fit - Works with most 330 mm sealant and adhesive tubes you’ll find at a local store.
• Simple Trigger Action - Easy to control bead size and stop/start dispensing on demand.
