Made of a titanium-nickel material, the Tinel-Lock ring also contains a thermochromic temperature indicator which changes color when the correct amount of heat is applied during the installation process. This aids the installer in determining how much heat should be applied to attain adequate recovery of the ring. Typical recovery results in about eight to ten seconds. The ring is lighter weight than banding straps, and there are no sharp edges. A wide selection of shapes and sizes are available, for additional information visit the website at http://www.tycoelectronics.com/catalog/feat/en/c/16535.
