Many improvements make our new tacker more durable and easier to use. The slender nose more easily parts yarns. The short overall height, narrow profile, and rounded cap are helpful in tight spaces. Also comes with a larger carrying case with more space inside, and a free staple saver box (No. 617). Takes Duo-Fast® No. 5418 or No. 5415 staples, Shur-Fast (No. 619D), or generics.
