Abstract
A hold open rod is provided. The hold open rod includes an outer tube, a lock body connected to the outer tube, an inner tube, slidingly disposed within the outer tube and lock body, the inner tube having an outer surface, and a friction pad captured between the lock body and the outer surface of the inner tube. A method for damping movement of a telescoping rod is also provided. The method includes attaching the locking body to an outer tube, configuring the outer tube and the inner tube to move with respect to each other in a telescoping manner, fitting a damper between an outer diameter of an inner tube and a locking body, and fitting the damper to frictionally engage the outer diameter of the inner tube and the locking body.
