$45.99
Product Overview
The Gulrear Sliding Door Air Conditioner Kit is a purpose-built venting solution engineered specifically for portable air conditioners installed through sliding glass doors or large windows. Designed to overcome the limitations of standard window kits, this system delivers reliable exhaust airflow while maintaining room insulation and preventing drafts. With a maximum adjustable length of 228cm (90 inches)—and an overall kit length of 256cm (101 inches)—it accommodates everything from standard patio doors to tall residential windows without compromising performance.
Constructed from durable PVC material, the kit features four interlocking plates that slide together seamlessly, eliminating traditional joint gaps that cause air leakage. The modular design allows users to customize the setup based on their specific window height or width, ensuring a precise fit without overextension. Whether you’re cooling a sunroom, apartment living space, or commercial office with sliding access, this vent kit provides stable airflow throughout hot summer months while keeping insects and outdoor elements out.
Key Features
- Max Adjustable Length: Extends up to 228cm (90 inches), offering flexibility for wide or high sliding doors and windows. Use only as many plates as needed—no need to install all components if your opening is smaller.
- Universal Hose Compatibility: Compatible with standard 13cm (5.1-inch) diameter exhaust hoses, commonly used in most portable AC units (note: actual hose and connector must be purchased separately).
- Durable PVC Construction: Lightweight yet robust panels resist warping, cracking, and wear, supporting repeated installation cycles and long-term use.
- Ingenious Seamless Design: Eliminates air leakage at plate joints by integrating smooth sliding connections, significantly improving seal integrity compared to traditional segmented kits.
- Easy Installation & Removal: No specialized tools required—simply slide, align, and secure using included hardware. Ideal for renters, seasonal setups, or temporary installations.
- Dual-Purpose Fit: Works effectively on both vertical and horizontal sash configurations, making it suitable not only for sliding doors but also for fixed or non-traditional window types.

Benefits & Use Cases
This vent kit excels in environments where conventional window AC vent systems fall short—particularly homes or businesses with large sliding glass doors, patio entries, sunrooms, or high-rise windows that exceed standard kit reach. Its extendable design enables precise customization, allowing users to match the exact height or width of their opening. This precision reduces unwanted drafts, maintains consistent indoor temperature control, and prevents energy loss due to poorly sealed vents.
Homeowners installing portable air conditioners in non-standard openings will appreciate the adaptability and ease of use provided by the sliding plate mechanism. The integrated exhaust hose adaptor ensures a secure connection between the AC unit and the vent panel, while the included high-density foam sealing tape blocks gaps between inner and outer window frames. This dual protection keeps cool air inside, stops warm air and insects from entering, and ensures optimal AC efficiency.
The modular structure also simplifies storage and reduces unnecessary costs—users can shorten the configuration if their window is narrower than full kit length. This makes it ideal for apartments, condos, mobile homes, offices, or any space where permanent HVAC installation isn’t feasible. Additionally, the lightweight PVC construction allows for easy transport and reconfiguration across multiple locations.
Installation Guide & Important Notes
Installing the Gulrear Sliding Door Air Conditioner Kit is straightforward and tool-free. Begin by measuring your sliding door or window opening to determine how many plates you’ll need. Align the fixing plates at the top and bottom of the window frame, then connect the adjustable plates as needed. Slide and lock them into place using the built-in screw-and-nut system, adjusting for your desired length. Secure the entire assembly with the included screws.
Next, connect one end of the exhaust hose to your portable AC unit using its original connector (note: the hose and connector are not included in this kit). Attach the other end to the exhaust hose adaptor mounted on the vent panel. Finally, apply the 4-meter sealing tape around the perimeter of the window frame—cutting it to size if necessary—and press firmly between the inner sash and outer glass to block gaps.
- The exhaust hose and hose connector are not included—they must be sourced separately, as they vary by AC brand model.
- Accurate measurements of your sliding door or window opening are essential before purchase to ensure proper fit.
- Do not exceed the recommended max extension of 220cm (87 inches) for optimal sealing and structural stability.
- Ensure the foam sealing tape is cut precisely and installed tightly between inner and outer window frames to prevent air leaks and insect intrusion.
- Package contents include: 2 fixing plates, 2 adjustable plates, 1 hose adaptor, 4m sealing tape, and 4 screws.
This innovative design completely eliminates edge gaps common in traditional sliding door kits, providing a tighter, more efficient seal. Whether you’re replacing a broken vent kit or upgrading an existing setup, the Gulrear Sliding Door Air Conditioner Kit delivers dependable performance, ease of use, and long-lasting durability—ensuring cool, comfortable airflow all summer long.

Perfect solution
I purchased this for my neighbor that had a portable air conditioner but didn’t want it in the bedroom. I started looking for a solution so they could use it in the living room using the sliding door. I looked at a few different ones and am so glad that I decided on this one. The fit was perfect and it was super easy to put in. They love that they can still open the door to go out while the unit is in place. Highly recommend.

Perfect
This was super east to install, took less than five minutes. It’s much better than the one that originally came with my portable AC. It’s already working more efficiently! I also now have the option to use it in my screen door if I so wish. Buy it! It’s also super sturdy.

Not perfect, but works with some tweaks.
This product works well with some slight modifications. I used it for a larger window that slides horizontally.Some notes:-I recommend buying your own weather stripping and using it on BOTH sides of the panel. The weather stripping provided didn’t seal the gaps.-I also recommend Gorilla Tape along the perimeter to provide extra seal and stability. The panel is skinnier than my window frame, so it wobbles without the tape. My window also doesn’t close fully onto the panel, more at an angle, which makes me think my window/frame is unbalanced.-I also used Gorilla Tape over the tube adapter. The adapter snaps into place, but there were some small gaps and I worried about my AC not working as efficiently as it could.It’s not pretty, but I don’t really care when it’s 102°F outside. My portable AC is working GREAT. I plan on placing a thick wooden dowel rod in the window for extra protection and stability.This is not a one-and-done product, you’ll probably need to get creative in order to get the best results out of it.I definitely think it’s over priced. It was nearly $50 for what is essentially a DIY project that cuts some corners for you.That being said, I am keeping it because am enjoying it so far. I like that even if I move houses and have different windows, this will still work because it’s customizable.

Not Really “Universal”
Everything about this kit is as you’d expect; simple, sturdy and easy to install, no issues there.Just one big issue: the exhaust hose interface did not fit the hose that my AC came with! Although the kit indicates that it works with “most” AC units, it was far too small to work with my AC. I had to enlarge their adapter plate to accept the exhaust duct supplied with my AC…quite a bit of modification, but I didn’t want to wait for something else to show up.It would be nice if the kit description included the hose diameter, so you can check for compatibility before purchase…

It works and fits 93 inch tall door!
Happy with it. Itâs more sturdy than expected, the interlocking pieces work better than what came with my Honeywell a/c unit. (Except for the end piece adapter)The only downside is you have to use the end hose adapter that comes with it, at least for the 5.1 size, as my own end piece adapters are slightly too large. The end piece is not as durable as what I already had.It easily extended up to 93 inches to fit my tall sliding glass door. Probably could extend up to about 95 with no issues. If you had an even taller door just buy 2 units as you could easily add another interlocking piece onto it.I still need to weather strip it and likely plan to buy that at the hardware store.Also, I have a 2nd one Iâm using in a tall window, so this works perfectly for windows too. It works and Iâm sitting cool at the moment!

Saved us from dying of heat in our own home
We unfortunately do not have Central Air and are saving up for it. This helped us so we could keep our kitchen/dining area cool. It was super easy to put together, and we can easily remove it at the end of the day so we can close our door for the night. Because of the foam provided, we got a pretty good seal. We choose to place it on our sliding door track so that it also uses the seal from our door/frame.Obviously, with it being 4 pieces of plastic, it can get a little flimsy the longer you have to extend it (so those closer to the 220cm/87inch will notice this more). But other than that, I’d say it’s a great choice if your sliding door is your best option for exhaust.

I purchased a portable air-conditioner, but could not use the enclosed window outlet as I have patio doors.When telephoning into Delonghi as to what I could do, this item was suggested as the measurements appeared to be suitable. However, the sizing of the Gulgear item is millimetres different and I am unable to use it at the moment, until I can come up with an idea of what to do. As this item came from the States I decided not to return, but to try and adjust accordingly. The item itself is of quality and some thought has gone into fitting it to a patio door,.

Die Lücke in der Schiebetür wird gut ausgefüllt, lediglich das Dichtgummi konnte etwas hochwertiger sein.
