PRE-HUNG DOORS

Installation-ready doors that arrive complete with frame, jamb, and hinges. Just hang and finish—no measuring, no adjustments, no hassle.

When deadlines are tight and labor costs keep rising, every installation hour matters. Hanging door slabs with separate frames is time-consuming, labor-intensive, and prone to alignment issues that slow your projects and eat into profits. At Big Rock, we eliminate those challenges with pre-hung doors that arrive factory-assembled and ready to install. Each unit is built to precise specifications, ensuring perfect fit and alignment every time—so your crew can install faster, move to the next job sooner, and deliver consistent professional results across every project. With customizable panel styles, competitive bulk pricing, and reliable delivery, we help you stay on schedule, reduce labor expenses, and keep your business running smoothly.

"Efficient installations start with ready-to-hang doors."

Why choose our Pre-Hung Doors:

  • - Install quickly with factory-assembled door units

    - Reduce labor costs and avoid on-site adjustments

    - Standard and custom sizes available for any project

    - Multiple panel styles and finishes to match your needs

DOOR HANDING

Left-Hand Inswing

Description: (From INSIDE)

Hinges are on the left, and the door swings inward toward the user.

Use-Case:

Common for interior rooms such as bedrooms, bathrooms, where swing space is inside the room and the left-hand hinge suits room layout.

Considerations:

Check clearance on the left side inside the room to ensure no furniture or obstructions.

Left Hand Outswing

Description: (From INSIDE)

Hinges on the left; the door swings outward from the room/user.

Use-Case:

Exterior doors or commercial spaces that require doors to open outward for safety, code compliance, or space efficiency.

Considerations:

Ensure exterior area is clear to avoid blocking paths and comply with fire codes.

Right Hand Outswing

Description: (From INSIDE)

Hinges on the right; door swings outward away from the room.

Use-Case:

Used on exiting doors in commercial buildings or homes where right side hinges and outward swing optimize usage and safety.

Considerations:

Confirm there is exterior clearance and code compliance for fire exits.

Right Hand Inswing

Description: (From INSIDE)

Hinges on the right, door swings inward toward the user.

Use-Case:
