The Rapid R311 is a professional, heavy-duty hammer tacker which is ideal for roofing felt, insulation, carpet underlay and plastic foils. The unique patented opening mechanism allows fast reloading of staples from the base. The magazine is opened with just a light push on the button. The comfortable grip and perfect balance gives excellent results with minimal effort and the all steel, heavy-duty construction ensures strength and durability. The tacker is compatible with Rapid No.140 flat wire staples 6-12mm which have a larger holding area against the material. It also has a reversible staple driver so that when one side wears down, the other side can be put in place. Its large protective plate minimises damage to the base material.
