Cable Overblowing Junction Box 1-1/4 inch SDR (89066)
DESCRIPTION
The GMP Cable Overblowing Junction Boxes have been designed to install a new cable or innerduct into an existing occupied 1-1/4 in., 1-1/2 in. and 2 in. innerduct (subject to space being available)
The Single Size Junction Box comprises an aluminum base and lid that form a pressurized air chamber into which one end of an existing occupied innerduct can be attached. The existing cable can exit the box through an opening that has 3 cable seal slots, one of which will house the seal to suit the size of the existing cable. The third branch is then connected to a GMP Cable Blowing Machine via a short slave length of innerduct for the installation of the extra cable or tube(s). A collection of seals ranging from 7.5 – 20 mm included with junction box.
