The Columbia Semi-Auto Taping Tool Kit can significantly increase your taping and finishing production capabilities when compared to hand taping. Semi-Auto taping tools greatly increase efficiency and consistency compared to hand taping and decrease waste, resulting in reduced material use. The corner and flat compound applicators can be attached to the Columbia Compound Tube, allowing drywall mud compound to be easily and evenly applied to flat seams and corner angles. The corner roller is then used to bed tape squarely and securely into inside drywall angles. The final touch is using the corner flusher to apply an equal, feathered finish to inside corners. The entire kit fits in the included convenient, custom-crafted tool carrying case, for easy transportation, storage and protection of your tools.
