The sleeve hammer is an installation tool used to drive the vertical dock pipe into the ground. It weighs 14 lbs. and consists of a 26″ long, oversized pipe sleeve, welded to a solid weighted shaft of 3″ in diameter. This tool provides a relatively easy and safe way to install the pipe into the ground with minimal effort. For those dock installers that install multiple dock vertical pipes we suggest purchasing a 4 cycle pnuematic hammer, please call for additional information.
