A rekeyable lock cylinder with a cylinder body and a plug assembly. The lock cylinder includes a plurality of key followers and a corresponding plurality of racks disposed in the plug assembly. The lock cylinder includes, for example, a locking bar for blocking rotation of the plug assembly with respect to the cylinder body to prevent unlocking of the rekeyable lock cylinder with an unauthorized object. In some embodiments, the locking bar is configured such that torqueing the plug assembly with an unauthorized object applies force to the locking bar without translating such force to the plurality of racks. This type of arrangement enhances torque resistance of the lock cylinder against attempted forced entry.

The present disclosure relates to a door handle having a grip with a first end and a second end. The door handle further includes an upper mounting plate coupled to the first end of the grip and a lower mounting plate coupled to the second end of the grip. A mounting post is coupled to the lower mounting plate and is configured to move relative to the lower mounting plate. Means for adjusting the position of the mounting post with respect to the lower mounting plate facilitate movement of the mounting post along at least two axes. The means for adjusting the mounting post may further comprise a rotating arm that is pivotally connected to the lower mounting plate and to which the mounting post is attached.
