GAMMA'S  Cold Shrink EDL Series Kits

Gamma's EDL series of cold shrink kits are a safe, easy and reliable method to seal coaxial connections. EDL is ideal for wireless communication towers and any other exposed coax interface. These kits are applied without flame and installed without tools. Simply pull the rip cord and the tube shrinks down around your connection. Foam strips are supplied for use on connectors with particularly small outer diameters. Once installed, the connection is weather proof and protected against dust or dirt that may find it's way into your connection.
