Easy Maintenance

Before Assembly

Confirm that you have received the correct 120 Gallon Reptile Enclosure, with listed external dimensions of 48 × 24 × 24 inches (121.9 × 61 × 61 cm).

Carefully unpack and inspect the glass doors, enclosure panels, frame components, steel mesh top, substrate barrier, cable-routing accessories, and supplied hardware.

Do not begin assembly if any glass panel is cracked or structural component is damaged.

Choosing the Installation Location

Place the enclosure on a stable, level surface capable of supporting the fully equipped habitat, including substrate, decorations, heating equipment, and the animal.

Allow enough clearance for the sliding front doors, overhead lighting, ventilation, and routine maintenance.

Assembling the Enclosure

Follow the assembly instructions supplied with the product. Make sure the frame and panels are properly aligned and secured before adding substrate or habitat equipment.

Do not force glass panels into position or overtighten hardware.

Check that the assembled enclosure is stable before use.

Sliding Tempered Glass Doors

Ensure both sliding glass doors are correctly seated in their tracks.

Open and close each door carefully to verify smooth movement.

Check for gaps that could allow small reptiles or feeder insects to escape. If a locking mechanism is included, confirm that it operates correctly.

Steel Mesh Top & Cable Management

Check that the steel mesh ventilation top is securely positioned.

The enclosure features eight designated cable-routing openings. The manufacturer describes the system as accommodating up to four cables, depending on their dimensions.

Route electrical cables through the designated openings without pinching or damaging insulation.

Keep wiring and electrical connections away from water and direct contact with reptiles.

Removable Substrate Barrier

The enclosure includes a transparent substrate barrier approximately 3.9 inches (9.9 cm) high.

Ensure the barrier is correctly positioned before adding loose substrate.

Remove or reinstall the barrier only as permitted by the enclosure's assembly design.

Heating, Lighting & Habitat Setup

Select heating, UVB lighting, thermometers, thermostats, and other equipment according to the requirements of the reptile species being kept.

Verify temperatures and UV exposure at the animal's actual basking position.

The mesh top may reduce UVB transmission, so lighting distances and measured output should be checked when selecting equipment.

Do not place heating equipment directly against materials unless the equipment manufacturer confirms that the installation is safe.

Cleaning & Maintenance

Clean the enclosure regularly using cleaning methods compatible with its materials.

Avoid abrasive tools and harsh chemicals that could damage glass, panels, seals, or frame surfaces.

Inspect the sliding doors, tracks, ventilation mesh, cable openings, and structural components periodically.

Important Safety Information

The enclosure has not been verified as watertight. Do not fill it with water or use it as an aquarium.

Stacking capability has not been confirmed. Do not stack enclosures without a manufacturer-approved stacking system.

This guide provides general setup and maintenance precautions. Always follow the official assembly instructions supplied with your enclosure.

Great Enclosure with a Few Assembly Tips

Five stars! This is a very good enclosure. It's sturdy, looks great, has plenty of space, and my bearded dragon loves it.

However, I wanted to share a few assembly issues we encountered and how we fixed them.
First, there were a few bends in the sliding door tracks, but they were easy to straighten out. The inside front panel was also slightly bent, which made it difficult to keep the sliding doors on their tracks. We solved this by placing a heavy rock or decoration against the panel, which worked well for our setup.
Lastly, the lock was a little finicky and loose. Tightening the installation screw with a wrench made it much more secure.
Overall, it's a great enclosure, and I'm happy with it. Just be prepared to make a few minor adjustments during assembly.

Ball Python Enclosure

I would like start off with, I absolutely love these things, I ordered 4, 2 pink for my girls, and 2 blue for my boys. They were packaged so nice, neat and organized, nothing came damaged at all. They are easy to put together, I put all 4, along with the storage cabinet spacers for stacking, together by myself, just a few short weeks after ACL reconstructive surgery. The colors are so nice as well, I thought they were a matte finish, but they actually a very nice metallic finish. I will however, out of my own paranoia, (I've had a couple snakes be escape artists in the past) be adding baby safety locks for cabinets on the doors, just to make sure they stay closed, as there are no locking mechanisms on the doors. Make sure the side vents aren't untwisted too far either, one of my boys knocked his out and tried to make a break for it, lol. I could not be happier with these enclosures, and if I aquire more ball pythons in the future, these will be my definite go to.

Gorgeous and economical tank!

I was a bit apprehensive about assembling my own tank, but let me tell you, this one is well worth it. My little boa boy Vega (currently 4.5 ft long) was in a 40 gallon, and is very happily making full use of the triple space upgrade. I love the fact that despite being triple the size of a regular glass 40 gallon tank, this 120 gallon tank weighs the same. It feels sturdy, looks great, and was pretty easy to assemble. Take care when assembling! The glass and plexiglass are so clear (after you remove the protective film) that my poor naked cat ran right into the plexiglass while we were assembling it. Sweet boy has no whiskers, and it’s very clear. Just something to keep in mind if you have mammalian pets, too. Definitely recommend! I also love that they’re stackable. There was one visible scratch on the front, but it’s not too noticeable.

Cost, Sturdy, Easy to Assemble, Not an Eye sore

The product is flawless in my opinion. Packaging was perfect to ensure no scratches or broken glass. The instructions was a little vague. My only complaint, but it isnt worth taking away a star on the review. BUT, there is a "how to assemble" video located on the items store page. Had I noticed the video beforehand, I would've had this assembled in 10 minutes. It took a little longer because I thought the back part of the enclosure was missing from the packaging. Whole time, it is attached to the base of the enclosure with a very subtle silicone type of adhesive that didnt leave residue. Silly me! The video explains and show this. The included instructions does not, or it is very vague.

Its sturdy not heavy at all, only 50 something lbs. Once you add decor, substrate, and your creature. They will change the weight of course. It is sturdy as well. I like how the side panels are clear but blurred. It gives my python the sense of security while allowing natural light into the enlcosure. I was also able to get it the next day shipping with Prime. I was gonna use Dubia website because it was roughly $80 cheaper minus shipping. But the shipping
