An automatic drywall taper is used to apply the first coat of joint compound and tape to flat and angled drywall seams. It significantly increases drywall taping efficiency, as it applies the first bed of compound and tape in 1 pass. The DEWALT automatic taper has an high-quality extruded aluminum compound tube that has been hard-coat anodized for extreme durability and easy cleanup. Internally, the finish ensures smooth operation while also prolonging the life of the premium urethane plunger. The head of the DEWALT automatic taper is precision machined from high-grade billet aluminum that is resistant to corrosion and premature breakdown. Side plates, internal plates, cable drum, drive chain and other components are stainless steel for long term durability. A quick-clean cover plate utilizes a single thumb screw for easy removal during cleaning. The DEWALT automatic taper features an integrated, trigger-controlled creaser wheel to efficiently sets the tape into drywall corners, as well as a quick-change tape holder that makes exchanging tape rolls fast and easy. For ultra-smooth operation, the DEWALT automatic taper utilizes a rolling chain idling system that reduces drag, as well as easy-glide wheels embedded into the control sleeve. An adjustable roller brake and cutting spring tensioner allows the user to customize the feel of the taper to personal preference.
