The PneuTools RNS150-II is a revolutionary new take on Single Blow Metal Connector tools. PneuTools designed a brand new True Positive Placement Nose and Magazine. Unlike other positive placement tools out there for joist hanger and metal connector applications, the RNS150-II gives you an ACTUAL positively placed fastener, every time. With the new nose design, the actual nail is the guide, not some clumsy probe that doesn"t always place the fastener in the hole, and puts you at danger of a ricochet when the fastener hits the metal plate. • With the nail-point being the guide, the fastener will be in contact with the wood surface you are firing into, so you don"t need to spend extra money on special heat-treated positive placement nails, which is what has to be used in other metal connector tools with clumsy probes, to ensure that the fasteners don"t fish-hook and come flying back at the user. • The PneuTools RNS150-II uses 34 1 1/2 Positive Placement Nails, with nail shanks of .131-.148 • It has a High Capacity, Easy-Load Compact Magazine and a Sleek Body Design, so you can operate Quickly & Effortlessly and not fumble with a hammer, or some other bulky joist hanger tool that just won"t fit where you need it to. • It also comes with a Convenient Belt Hook, and of course - the Easy View, Nail-Point Installation Nose, so no clumsy probe or expensive heat-treated nails are needed.
