Review: Catio Door, Quality Product, Outstanding Company - The bottom line: This is an attractive, high quality barn door kit, with heavy-duty hardware, available at a very good price. It's easy to install, with excellent instructions. It works well for my sliding catio screen door. The company, SmartStandard, is exceptional and provides superior customer service. I highly recommend this product and buying from SmartStandard. The details: I purchased this barn door kit earlier this year when planning a small catio for a rescued kitten. I bought a used/returned kit to save a few dollars. The catio was planned to fit against the house on a walkway outside bedroom windows from which the cat would access the catio. I did not want a swingout door on the catio front because the catio was going to be adjacent to a patio with an above ground pool and a small rocky garden area with a small potted tree. There was limited room to pass and open a door, and I thought a sliding door would work best. Hanging a door with barn door hardware seemed like the best DIY option (for me, a 63 y/o woman). The catio is constructed with two 7' tall shelving/cabinet units that someone was discarding (which I sanded, primed/sealed & painted for exterior use), connected by a roof (made of 2x4s and corrugated metal), with a stationary screen panel "wall" and a sliding screen door on the front between the two cabinet units. I cut out windows on both sides of the cabinets, on the outer sides for windows (framed with pet proof screen and hardware cloth) and on the insides for the cat to access from the catio main interior. On the front open shelves of the cabinets, I screwed on decorative screen panels, with pet proof screen adhered to the backs of the leaf design panels (to keep insects out and little cat arms/paws in). While I believe the barn door kit is for interior use, I planned an overhanging roof eve over the catio front and sides so it would be sheltered, and I also put up some hooks to hang clear shower curtains (3) stringed on a clothes line around the catio when it rains. The catio is west facing, in the South Bay area of Los Angeles, and could get wind-driven rain. For much of year, it will get a lot of sun. (Raining now, so one of my pics includes the shower curtains.) The catio is 11' wide, 2' deep, 7' tall, with a 7' open space between the cabinets that stand on each side. I used a 7' long 1x6 board between the two cabinets, as a header board on which to mount the barn door rail. While the kit includes heavy duty long screws and anchors for mounting the rail, I bought some nuts and bolts (5/16-18 x 3"), because I was not mounting the rail into a wall but only on to the header board. I was also planning a lightweight screen door. I decided to make the stationary screen panel wall and the sliding screen door both 4' wide, so there would be a foot overlap in the center, for added security. While I was originally going to mount the stationary screen panel wall flush with the header board, I decided to secure the front frame of the screen wall, and a strip of wood vertically on the right (for the door to overlap when closed), to the front of the header board, under the door rail, to narrow the gap between the door and the stationary screen wall the door would slide over. The stationary screen wall and the screen door have screen and hardware cloth stapled on and sandwiched between 3/4" thick wood, making them 1.5" thick around their frames. I also made my own door glides for a secure fit, so I would not have to worry about the cat trying to squeeze out the sides of the door. Since I was working on this primarily by myself, everything took a lot longer than I anticipated. (I had a vision, a general plan in my head, working out the details as I went along, and initially thought it would take a few weeks to a month. It took 4 months after starting the work to completion.) When I finally got to the point of building the door, a few months after purchasing the barn door kit, I found the kit (which I had bought used/returned) was missing the two anti-jump "rubber ends" that attach to the top of the door and prevent it from lifting off the rail. Upon discovering the kit was missing the two small parts, I contacted SmartStandard to see if they could send the missing parts. If not, I was prepared to buy some but thought I'd ask first. I emailed the company at the contact email I found on desertcart. I received a professional, friendly, and gracious response within a day, offering an extremely generous resolution. It was more than I would have asked or expected, and I tried (unsuccessfully) to decline; because the parts were not available to send separately, SmartStandard sent a full replacement kit. The replacement kit arrived within a few days. I can't remember a time in my life when I have received such professional, kind and courteous responses to my customer service inquiries. Each time SmartStandard responded to my emails, including a couple after my initial inquiry about the small missing parts, it was with kindness, professionalism and enthusiasm for my project. The barn door hardware was easy to install. It works perfectly for my catio door, and it looks great. SmartStandard has been absolutely lovely to work with. I will definitely look to SmartStandard's products for other DIY home projects. I recommend this kit and SmartStandard products without reservation. Review: Smooth and whisper quiet - This barn door style hardware set is a dream come true. The size was perfect for the door that I made, and it’s incredibly sturdy and durable. The placement of the bolts didn’t match up with the stud pattern on my wall, so I had to put up a support board behind the rail like what is shown in the listing, but that was no problem. The wheels glide along the rail smoothly and quietly which is very satisfying, and it requires almost no effort to move the door back-and-forth along the rail. I figured it would make some noise like the pocket doors in bathrooms or perhaps even a closet door, but it’s whisper quiet. The instructions were simple and straightforward and did not require any specialty tools to install.. Fantastic quality for the price and it works incredibly well. If you’re having any doubts about which one to get, I would recommend this one. ## Features - 【WHY CHOOSE US】Our track comes in two solid pieces, instead of mutiple small pieces.
