Set of lock jamb, hinge jamb, and head jamb (2 sides and top) for a single interior door. Stain grade poplar can be stained or painted to match your desired look. Solid poplar in double rabbeted construction means the stop is built into the jamb (rather than applied separately), providing unparalleled durability, stability, and ease of installation. Select size to fit doors from 12" to 24" wide, 80" tall, and 1 3/8" thick (standard interior door thickness): Note that head jamb should be 3/16" (.1875") wider than actual door slab. This is to ensure smooth operation, allowing our recommended 1/16" space on the hinge side and 1/8" (2/16") space on the strike or lock side Since interior doors often measure the full nominal width, for example a 3/0 or 36" door will measure a full 36.0", we send our head jambs with sufficient length to work for these full-width doors If your door measures between sizes, just buy the next size up and sand or cut head jamb to fit Key Specifications: Designed for interior doors 1 3/8" thick Length: 81 3/4" Perfect for 80.0" interior doors while still leaving clearance for carpet, can also be easily trimmed shorter off bottom as needed Depth: Select 4 9/16" or 6 9/16" 4 9/16" are standard depth jambs for use with typical (2x4) construction 6 9/16" are extended depth jambs for use with (2x6) construction Thickness: 1 1/8" including stop, 11/16" thick not including stop Handing & Prep: Select Right or Left Handing: Hinge or lock prep jambs: Stand in the room that the door swings into - if the door handle is on the right hand side or the door you need a right hand lock or hinge jamb.
