Majestic Slimline Christmas Trees are designed for quick and easy assembly.
In this video, we'll show you how to install a 15-foot slimline tree.
This same assembly process applies to the 12-foot, 15-foot, and 18-foot styles.
All you'll need is a Phillips head screwdriver, a ladder, and an extension cord.
Each tree ring is labeled in reverse alphabetical order from floor to top,
with the lowest ring being the last letter in the sequence.
The total number of rings will depend on the height of your tree.
Start by locating that base ring and placing it where you want your tree to stand.
Next, attach the four stabilizer brackets around the outside of the base ring.
Each bracket attaches using the supplied bolts,
wing nuts, and flat plates, and there are two sets per bracket.
Space them evenly to ensure the tree remains stable and upright,
and avoid grouping them on one side.
Tighten each by hand until secure, then double-check that the brackets are evenly spaced.
Use your screwdriver to fully tighten the brackets and hardware.
You're ready to build the frame.
The slimline tree frame has a stacking ring design,
and the rings will layer from the ground up in reverse alphabetical order.
Align the power cords within the frame to keep your electrical outlets safe and easy to locate.
Secure each ring to the one below it with the hardware.
Evenly space them along the rings to make four connection points at each level.
Continue this process until you reach the top ring.
The top ring features a pole mount where the top foliage will go.
Next, it's time to install the tree foliage topper.
The topper comes in two parts.
Before climbing up the ladder,
fluff out the branches on each section to shape them and give them a full, natural look.
Insert each piece securely into the top frame.
Smooth out the seam between the tree topper pieces with some additional branch fluffing.
Locate the topper plugs and connect them together back to back.
You'll then connect this to the tree's main harness plug.
Remove the zip ties from the main plugs that are secured to the ring frames,
and drop them to the ground.
Using a three-way plug and an extension cord,
connect each of the main power cords and plug in the tree to power it up.
Now with power running through the harness,
plug your tree topper lights into any of the female plugs in the top harness.
It's important to never stack more than five light set plugs together.
Check that every section lights correctly before moving on to branch installation.
Now it's time to bring your tree to life.
Each branch simply hooks onto the corresponding ring frame.
Before hanging, fluff out each branch to give it a full shape and natural look.
This helps eliminate gaps and ensures even coverage.
Plug each branch into the next,
but be sure not to stack more than five plugs together at any one point.
Continue attaching and fluffing branches ring by ring.
Once all branches are installed and connected,
step back and inspect the lighting and foliage.
Make any final adjustments to shape the branches,
especially around the seams between ring frames,
for a seamless and full appearance.
And just like that, your slimline Christmas tree is ready to light up the season.
