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 a lightweight throwline) with high accuracy using a 12oz or 14oz Harrison Rocket throw bag. Using the DTX Shoulder Shot dramatically decreases the time spent installing a throwline. Constructed in non-corrosive materials and a 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 quickly refill the air chamber with a handheld air pump or small compressor. USA made.
