With the Dripless feature, the rod retracts after releasing the trigger and removes pressure from the tube to help prevent dripping. The frame rotates to maintain the bead orientation when caulking around corners. Don’t get down—the hook on the back allows the gun to hang on a ladder. A seal poker and spout cutter are built into the side of the gun for opening cartridges without a knife. Dripless is a registered trademark.

Sadly, it's not.I've used it about a dozen times now, and I've found myself repeatedly being happy with it one moment and cursing it the next. More cursing it, honestly. Seems every time I'm on a ladder or reaching at full extension, when I need it to just work, it fails me. Meaning, almost no pressure. Squeezing the trigger/handle over and over and getting nothing. Other times i get good pressure.Either way, there's almost always some drip, regardless of the viscosity. I honestly thought it I was crazy for using my trusty $4 caulk gun all these years, so I decided to upgrade. Now I reach for the old cheapo more than this thing.I'd say I wish the pressure could be adjusted, but I know that wouldn't fix it. It's way too sporadic - very little pressure to too much pressure in the same tube, this happened on 6 tubes of the same product one after the other. Very frustrating. ### ⭐⭐⭐⭐⭐ If your a pro you need it . *by D*** on Reviewed in the United States on July 5, 2021* I have used multiple caulk guns and this by far is the best. it is metal which is a little bit heavier than the plastic one but it is dripless the "i3000" is not dripless like it says it is . If you use it everyday and want a great caulk gun that is dripless this is the one ! Out of the 5 I own I pick and use this one daily . --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/1096967-contractor-grade-heavy-duty-caulking-gun-dripless-caulk-gun-mid](https://www.desertcart.vn/products/1096967-contractor-grade-heavy-duty-caulking-gun-dripless-caulk-gun-mid) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
