How to Measure

The goal when measuring your jamb for our interior steel single doors is to get the measurement from the outermost finishings of your walls (drywall, trim, etc.). To get this measurement, make sure that you're including all parts of the building materials and the finishings.

These interior steel single doors are pre-hung and include both the door and fully assembled frame for ease of installation. The jamb size is measured at 1.5” and made from Ottostumm hot rolled solid steel.

Strike Plates

Strike plates, which are typically included when purchasing a lockset, are the plates that receive the throws of the latch and deadbolt and secure your door in place. All of these interior steel single doors come with laser cut strike plate openings on the frame of the door, and feature pre-drilled and pre-tapped holes for machine screws. (Standard in-stock interior steel single doors will have a single bore hole / strike plate cutout for passage hardware. Double bore holes are available via our made-to-order section).

Hinges

These interior steel single doors come standard with modern bullet hinges. The frame will have the bottom portion of the hinges welded on (Hinge and male pin). The top receiving portion of the hinge will be welded onto each door leaf, and include a screwed in grease fitting, allowing you to maintain and grease the hinges regularly via a standard grease gun. 

One copper crush washer per hinge is included and required prior to hanging the door onto the frame. These washers protect the hinges by introducing a softer copper metal between the 2 hinge components in order to absorb the friction and allow the doors to swing smoothly. This hinge system is far superior to ball bearing systems, as the bearings are made of stainless steel, which is a harder metal inside a steel barrel, causing wear to both components and sagging over time.

Bolt-Through Design & Modular Capabilities

These standard steel interior single doors feature a bolt-through design. Pre-drilled holes along the frame’s perimeter allow for versatile mounting options within the rough opening of various framing materials.

These pre-drilled holes also allow you to take advantage of our modular interior door system. This system enables you to create full or partial wall partitions by pairing the door with one or more of our interior side windows.

Door Thickness

These standard steel exterior single door leafs come standard at 2” thick, providing both security and durability. Keep this thickness in mind when sourcing locks, as some locks will not be compatible with a 2” thick door without the inclusion of a thick door kit (based on lock manufactures availability)
