These are direct replacement lock sets for our SRD model rack drawers. The lock set includes a lock and two keys. These are not intended for our previous old style rack drawers. The old style rack drawers had a bent tang where as the new style rack drawers have a straight tang. Also, the new style rack drawers are all keyed the same. Please note that the lock set in the picture shows our old style with the bent tang. A new picture of the new style lock set will be posted soon.
