Standard types of door preps refer to the various configurations and preparations made on doors to accommodate specific types of hardware or accessories. Here are some common types of door preps:
Bored Hole:
A bored hole prep refers to a hole drilled through the face of the door to accommodate a specific type of hardware, such as a doorknob or lever handle. Bored hole preps are typically done at a standard height and diameter to fit the specific hardware being installed.
Crossbore Prep:
A crossbore prep involves drilling two intersecting holes in the door, typically at a standard height and diameter. This type of prep is commonly used for installing deadbolt locks or interconnected locksets that have separate doorknob and deadbolt components.
Mortise Prep:
A mortise prep involves creating a rectangular pocket or recess on the edge of the door to accommodate a mortise lock. Mortise locks are typically larger and more robust than standard cylindrical locks, and the mortise prep provides the necessary space for the lock body and associated components.
Hinge Preps:
Hinge preps are the recessed areas or cutouts on the edge of the door and the corresponding jamb or frame where the hinges are installed. The number and size of hinge preps depend on the door size, weight, and type. Common hinge configurations include three hinges for standard interior doors and four hinges for heavier or exterior doors.
Strike Plate Prep:
A strike plate prep involves creating a recess or cutout in the door jamb or frame to accommodate the strike plate. The strike plate is the metal plate that the door's latch or bolt engages with when the door is closed. The prep ensures proper alignment and positioning of the strike plate for secure door closure.
Cutout Prep for Glass Inserts:
In some cases, doors may have cutout preps to accommodate glass inserts. These preps involve creating an opening or cutout in the door panel to allow for the installation of glass or decorative inserts. The size and shape of the cutout depend on the specific design and dimensions of the glass insert.
It's important to note that the specific types of door preps may vary depending on the manufacturer, door type (e.g., wood, metal, or fiberglass), and the hardware or accessories being installed. Different preps may be required for specialized hardware, such as panic bars, door closers, or access control systems. When purchasing doors or planning for hardware installations, consult with the manufacturer or a professional to ensure that the door preps align with your specific requirements.
