Abstract
A device for providing access to the interstitial region between an inner pipe and an outer pipe which coaxially define the region. The inner pipe has at least one terminal end extending from the outer pipe to leave a portion of the outer wall of the inner pipe exposed to thereby expose the interstitial region. A boot is provided for defining a chamber with a larger end snugly fitting the outer pipe and a small end snugly fitting on the exposed outer wall of the inner pipe. The boot has an access port communicating with the interior of the chamber to provide access to the interstitial region.
