This is the new Ramset Viper 4! Engineered for safer more reliable firing, the Ramset Viper 4 uses a less expensive sectional pole, sold separately. Base pole is 6 foot add as many 3 foot extensions to reach desired height. (The Viper 4 will not work with older Viper or Lagmaster poles. Viper 4 pole is requred) The Viper is the premier tool for use in over head fastening. With it's lightweight, automatic load advance and piston return, this is the tool of choice by ceiling contractors, electricians and low voltage contractors.
- .27 caliber, 10-strip loads: 3 (Green), 4 (Yellow), 5 (Red)
- Weight: 4.5 pounds
- Maximum Pin Length: 1-1/2"
- Length: 17 inches
 The Ramset Viper 4 Overhead Tool
The Ramset Viper 4 tool is a powder actuated tool designed exclusively for fastening overhead. All though being limited to overhead work, it does it well and is quiet and can be extended to longer lengths using extensions. The tool requires a V4-6 base pole. Please note that poles used for the older Viper series of poles will not work. The Viper 4 is a .27 caliber tool, so loads are easy to come by. The “rattle” you hear in the back end of the tools is a lockout ball that prevents the tool from firing unless it in an upright position.
Who Is Ramset Viper 4 Designed For
The obvious user of the Ramset Viper 4 would be a ceiling contractor but there are other trades that routinely use the tool. Electricians use them for shooting up lighting fixture support wires, BX cable and more. The tool will shoot a ¼-20 or 3/8” rod hanger clip as well. Data Comm, security and low voltage contractors use the tool to support cable runs with grid wire, ¼” all thread and ceiling clips to run smaller cable runs. A J-Hook is available with a ceiling clip attached so you can shoot up a j-hook to a concrete deck from the floor. Signage contactors are another trade that can find a use for the Viper 4. So, in a nutshell, if you want to suspend from the concrete deck the Viper 4 is a good choice. About The Pole Tool System For The Viper 4
As mentioned above, the Viper 4 requires a pole tool to fire. You would start with what is called a trigger or base pole part #V4-6. These are 6’ long and have a trigger slide handle that actuates the tool. From there, you can add the V4-EXT 3’ extension poles, as many as you need to reach your desired height. The pole system for the tool is super stable so reaching higher decks isn’t an issue. Firing The Viper 4 Tool
I just wanted to cover the firing procedure for the Ramset Viper 4. While it is straight forward, it is different than the previous generations of Viper Tools. With the earlier versions of the Viper tool, you could simply push up on the pole to fire the tool. With the Viper 4, you need to first depress the tool against the works surface and then push up on the trigger slide to fire the tool. If you just try to “harpoon” the tool, the timing will be off, and it may fire and it may not. Be deliberate with the tool. Compress the tool, then slide up the firing mechanism.
Repair Parts For The Ramset Viper 4 Tool
As for repair parts, I would recommend having a spare piston or driver, a set of return dogs and a buffer on hand. These are wear parts and having them on hand will keep you going. We have a video showing how to replace the piston here. Click here for common repair parts as well as an owner’s manual that features a schematic. I would not recommend opening the back end of the tool. It’s a little tricky. Not super complicated but if you don’t do it a few times, you may struggle.
