The 18:1 AWF PRO Caulk Gun is a high-performance manual caulking tool engineered for professionals who demand precision and power in every application. Designed to fit industry-standard 10 oz cartridges, this caulk gun delivers smooth, consistent output even with medium- to high-viscosity materials like construction adhesives, sealants, and heavy-bodied caulks. Built with an 18:1 mechanical advantage, it produces up to 18 lbs of dispensing force per 1 lb of hand pressure, making it ideal for heavy-duty use without hand fatigue. A pivoting barrel rotates for seamless application around corners and tight spaces, while its thumb-activated pressure release tab instantly stops material flow to prevent drips and mess. Durable construction elements like a sintered steel catch plate and wear-compensating mechanism ensure longevity and reliable use in tough job site conditions.
