1. PRODUCT DESCRIPTION
The Model HCI+2 2-foot “I-rail” extension is designed to be compatible with
the Model HCI-12 12-foot chain-drive “I-rail” used in commercial garage door
installations and in carriage house garage door installations. The 2-foot extension,
when added to the 12-foot “I-rail”, provides a 14-foot long rail for operating high-lift

short lengths of chain to extend the stock chain at the turnbuckle.
