Working with PVC trim, molding, or decking? This manual dispense gun is made specifically for H.B. Fuller's PVC TrimWelder adhesive cartridges. It's designed to handle 220 mL cartridges (the size used for many high-strength construction adhesives). The gun is built from tough, glass-reinforced nylon plastic, so it's lightweight but still durable enough for job site use. The breach loads easily and holds the cartridge securely to prevent slipping or wobble while you're applying adhesive. A wear-compensating mechanism and a case-hardened steel catch plate mean this gun is built to last, and all the parts are replaceable if needed. It works with both high and low viscosity adhesives, reducing hand fatigue during big projects. Whether you're a pro contractor or a serious DIYer installing PVC trim, this gun gives you better control and makes dispensing those thicker adhesives way easier.
