GENERAL SPECIFICATIONS

DOOR CONSTRUCTION: Double hinged doors are required. The hinges and hinge pins must be non-removable. Each door must have an internal stiffener, minimum #14 gauge.
LATCHING MECHANISM: A three point latching mechanism that secures both doors is required. The latching bars must pass through a guide that assures correct latching. The latching mechanism cannot protrude more than 1" inside the cabinet. All connection bolts must be permanently secured to prevent accidental contact of any metal part should the latching assembly fail.
LOCKING PROVISION: The latching mechanism handle must be designed to provide a locking provision in the closed position. This locking provision must accommodate a minimum 1/4" hasp. Key locking of the handle is not allowed.
CATALOG NUMBER: The catalog number (as listed by PPL) must be permanently marked on the inside of the right door.
