Abstract
A hold open rod is provided. The hold open rod may include: an outer tube; an inner tube having two ends, at least one end configured to slide within the outer tube; a tube stop located at one end of the inner tube; a groove around the circumference of the tube stop; and a resilient material located in the groove, the resilient material contacting the tube stop and the outer tube. A method of reducing wear on a hold open rod may be provided. The method may include: locating first resilient material between an inner tube and an outer tube; providing a locking mechanism to lock the inner tube with respect to the outer tube; and providing a second resilient material between an isolator and a collar on the locking mechanism.
