A tapering assembly compresses a butt end of a barrier into a tapered end for enhanced installation. The barrier includes sheet rock panel. A plurality of rollers and at least one taper roller pass through a front end of a plate portion. The barrier passes through a predetermined distance between the taper roller and the plurality of rollers. The taper roller includes a gradient taper. The plurality of rollers guide the barrier against the taper roller. A rear end of the plate portion includes a bearing that enables the taper roller and plurality of rollers to pass through. A taper roller shaft extends from a rear end of the plate portion. A variable speed drill rotates the taper shaft to provide rotation and torque to the taper roller. The barrier butt end is tapered without causing damage to the barrier from the position and precision calibration of the rollers.
