Handcrafted Box Beams Installation Guide by The Tree Knot

Box beams are an architectural solution that adds depth and structure to a space—without the weight, cost, or complexity of solid timbers. Whether you're transforming a living room, finishing a basement, or upgrading a kitchen ceiling, the right beam profile can instantly elevate the entire look.

Why Choose The Tree Knot Box Beams

At The Tree Knot, every beam is handcrafted with furniture-grade joinery, clean mitered seams, and real-wood materials designed for lasting performance. Our most popular size—7" × 7" with a 5½" interior opening—is engineered specifically for fast, accurate installation using a standard 2×6 mounting board.

In this guide, you’ll learn exactly how to install our box beams in a clean, professional way. Here’s the process at a glance:

1. Install the 2×6 mounting board

2. Slide the beam over the mounting board

3. Secure using 15-gauge finish nails

4. Perform final adjustments and touch-ups

Below, you’ll find the full walkthrough with diagrams and pro tips.

Why Our 7×7 Box Beam Is the Standard

7×7 profile isn’t just popular — it’s purpose-built for easy installation.

The inside dimension is 5½ inches wide, matching the actual width of a standard 2×6. This creates a reliable, snug fit and gives installers a consistent mounting method across every project.

Benefits of this design:

• No custom blocking required

• Faster installation

• Cleaner seam alignment

• Tighter fit against ceilings and walls

• Works well for both single beams and multi-beam layouts

Materials Needed for Installation

Before starting your installation, gather the following materials:

• The Tree Knot 7×7 wood box beams (ordered lengths)

• 2×6 lumber for mounting boards (cut to ceiling joist length)

• Level

• Measuring tape

• 15-gauge finish nails

• Nail gun or hammer

• Safety glasses

• Work gloves

• Wood filler or matching stain for touch-ups

• Ladder or scaffolding (depending on ceiling height)

  
  

Wearing safety glasses and gloves protects you from wood splinters and nail injuries during installation.

Step-by-Step Installation Instructions

Step 1: Install the Mounting Board (2×6)

The mounting board is the structural core of your installation, ensuring stability and support. It anchors into your ceiling joists and supports the box beam's weight.

How to install it correctly:

1. Use a stud finder to locate joists.

2. Mark placement using a level or laser line.

3. Secure the 2×6 directly into joists using structural screws.

4. Confirm the 2×6 is straight along its length — the beam will follow it.

A precise, level mounting board ensures a perfect final fit.

Step 2: Slide the Beam Over the 2×6

Built with precision 45° mitered seams, our beams give the appearance of a solid timber once installed. The interior cavity is dimensioned to glide smoothly over your mounting board.

Installation tips:

• Have two people lift longer beams.

• Slide gently to avoid scuffing interior surfaces.

• Check for alignment at both ends before securing.

Once in place, the beam should sit naturally around the 2×6 with minimal play.

Step 3: Secure the Beam Using 15-Gauge Nails

With the beam seated correctly, fasten it to the hidden 2×6.

Recommended fastening pattern:

• Use 15-gauge finish nails

• Approx. every 12–14 inches along both vertical sides

• Avoid the bottom face for the cleanest appearance

This gives the beam strong, even support while keeping fasteners discreet.

Step 4: Final Adjustments & Touch-Ups

After fastening:

• Inspect seams

• Ensure the beam sits flush against the ceiling

• Fill nail holes with appropriate filler

• Wipe down the beam surface
