The EP-2 lock preparation machine can be set to automatically drill for the face bore, (2-1/8" diameter standard), drill for the latch bore, and rout for the rectangular latch plate. All of the functions are set by switches on the control panel.

For metal doors the EP-2 uses a tapered cone to position the door in the face bore that was machined in the Door light Cut-Out Machine (Typically a Kval DL-NCA or DL-NCB) to machine
for the rectangular latch plate and drill for the latch. The face bore drill is turned off. Additionally a metal sensing switch may be added to insure that the face drill does not operate when a metal door is loaded in the EP-2.

For fiberglass doors the EP-2 can automatically perform all of the functions for the lock mortise. When machining fiberglass doors a stop system is used in place of the locating tapered cone that consists of two stops, one for the lock mortise, and one for the dead bolt mortise. The stops are adjustable to accommodate doors that vary in height from 6'-6" to 8'-0". The stop assembly is mounted on the in-feed end to position doors that are being fed sill end first.
