The DTX Shoulder Shot is ideal for utility companies, fall protection and roofing contractors, rescue organisations and arborists for fast, accurate throwline installation. The DTX Shoulder Shot can reach a vertical distance of 30+ meters (using light weight throwline) with high accuracy using a 10oz or 12oz throw bag. Using the DTX Shoulder Shot dramatically decreases the time spent installing a throwline. Constructed in non-corrosive materials; welded stainless steel air chamber with a clear PVC barrel, the DTX Shoulder Shot features a built-in, spring loaded, safety latch to prevent accidental misfires. You can refill the air chamber very quickly with a handheld air pump or small compressor. USA made.
