Coach Built Replacement Habitation Door Hinges for Obsolete Ellbee In Five and Three Part sections. “ I snapped a Lower Hinge on my Auto-Trail Cheyenne 630, 2002 Habitation Door and joined Motorhome Fun in the hope of finding an answer as I could not locate a Hinge anywhere. A Member put me in contact with Bill. His replacement Ellbee 5 Part Hinge was superb in quality and better than the manufacturers original. If you are in need of an Ellbee 5 or 3 part Hinge, I strongly recommend this individual. Bill is also prepared to give good advice regards fitting and using Silicone Greece on the Hinges.
