PRO NMEA Buffer - 1 OPTO Input, 6 ISO-Drive Outputs, Serial Port, Pluggable Screw Terminals
Safely connect one Talker to six Listeners with full isolation.
The Type-approved NMEA Buffer PRO-NBF-1 Buffer isolates and buffers NMEA 0183 data, with the power to drive multiple devices.
Able to distribute up to six identical, amplified streams of data from one source, the NMEA signals are buffered to ensure that each Listener receives the data at the required voltage levels, providing consistent data quality.
Isolation of the input and outputs ensures the protection of the source Talker device and Listener devices.
The NMEA Buffer has ISO-Drive™ technology on the outputs and OPTO-isolation on the input, which enables you to connect the NMEA 0183 Buffer with complete peace of mind.
The stainless steel housing makes the device rugged, sturdy, and gives it increased durability. The metal case also acts as an RF Shield, making the device an ideal addition to commercial installations.
To make installation quick and simple, the PRO-NBF-1 features 2-part pluggable connectors that allow use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.
The optional strain relief brackets can be provided to ensure reliable professional cable management.
Helpful LEDs indicate power, input, and output operation.
Features:
- One Opto-Isolated Input
- Six ISO-Drive™ outputs
- Outputs automatically track the input baud rate
- RS-232, RS-422 and RS-485 Listener compatible
- ISO-Drive separates the Listener from the Talker to protect both the PRO-NBF-1 and each connected device

Great for my tidy mind. Now the cabinet is organized and clean. Space saving too
Size: Left Facing, Size: Left Facing
Easy install. Glides nicely holds the jars without much movement. The labels are wonderful. I am super pleased. We bought 4 left facing for our cabinet. Not done replacing all the jars and such. But you can see a good idea how it will be. The fit out needs perfectly and looks great. I really like how neat and good visibility too. They seem sturdy with all the weight of the filled bottles also.

Great space saver, keeps everything organized.
Size: Left Facing, Size: Left Facing
I am soooo happy with this purchase! I’ve been researching lots of spice racks to see which ones would best suit my needs. This definitely fits the bill.
This product was perfect. It includes everything you need to organize your spices: the rack, screws, stickers, bottles, and a white gel pen to write additional spice names. The rack is heavy duty and sturdy. Once anchored to your cabinet, there’s no way it’s falling out.
The bottles are a good size and you can transfer standard store bought spices directly into the bottles. An additional asset is that the bottles come with a shaker spout that has two options for use. It can easily snap off and on when refilling.
The stickers are well thought out. They’re good quality labels and can easily be repositioned. I accidentally had an edge stick to the middle of a bottle and was scared that it wouldn’t come off. I was happy that it lifted up cleanly and didn’t wrinkle the sticker.
I didn’t have a need to write a lot of new names, except for two so far. Using the pen included, I wrote labels for Dashi and Seasoning-Arrachera. I tried to match the font of the labels and I think I did a pretty good job. You wouldn’t notice it was hand written unless you really stared at it. The white pen is great and so easy to write with. I didn’t have to go over any letters. One pen stroke was enough.
It also came with labels that you can place on the side of the rack for easy identification. I haven’t put them on mine yet because I still need to buy two more racks to store all my spices. Then I can get them all organized the way I want.
This is such a space saver. One of my absolute favorite purchases!

Absolutely worth the money!
Size: Left Facing, Size: Left Facing
I can't say enough about these spice racks! I have kept my spices in a corner cabinet on lazy Susans for the last 25 years and that's worked great, but it did not have much curb appeal and some spices were in the middle of the caddies so I would have to pull the front ones off to get to the middle ones. Corner cabinets are tricky and can be such a waste of space, but I made it work. But now it doesn't just work, it sings! My husband bought me 4 units and they fit perfectly in the space. Whoever designed these racks thought through EVERYTHING. The labels are well organized with plenty of obscure herbs and spices as well as all the common ones, and some blank stickers for the products they don't have labels for. There is a list of all the spices and which page you will find the label. There are also small corresponding labels to put on the ends so you know which rack has your spice (I haven't put those on yet because I want to make sure I have everything where I want it first). Since I have 4 sets of labels, I used some for labeling the baskets where I have the extra spices for refills. The racks are sturdy and easy to install. These would also work well in cabinets that are not corners - you would pull them straight out and it would make it easy to access all of your spices. If I could give this 10 stars, I would.

Fabulous!
Size: Left Facing, Size: Left Facing
I wish I had remembered to take a picture before I emptied my spice cabinet. Actually, on second thought, it would be embarrassing to share. I have two of these sturdy slide-out spice racks and could use another one. The racks were not hard to install, slide smoothly, look great, and my spices are in order! I was able to fit two of them on one side of my cabinet. I love the jars and labels. I use some spices much more than others so I put the matching labels on the large containers of these spices and keep them on the top shelf. I would definitely buy these again!

Clever Space Saver with a Few Caveats
Size: Left Facing
This spice rack system really helped bring order to the chaos in my cabinet, and it looks great doing it. The vertical design makes spices visible and accessible, and the included 20 jars and 801 labels are a huge bonus for customization.
🧩 Easy to Install, But Drawer Direction Matters
Setup is fairly simple, but take note: the drawer only slides out in one direction depending on which version you buy (left or right facing). As a reviewer noted on page 6, it’s not reversible, which can be a headache if your layout changes or you order the wrong orientation.
🪛 Build Quality is Solid but Assembly Could Be Smoother
The frame is sturdy and feels well-made, but you’ll need to screw the rails into the base — and the screws included aren’t the best. One user suggested bolts instead of screws (page 6), and I agree. A little more care here would elevate the overall experience.
🌶️ Jars and Labels Are Fantastic
This is where the system really shines. The jars are glass with metal lids and fit perfectly in the rack. The label set includes multiples in several fonts, blank ones, and even a chalk marker — very thoughtful!
✅ Pros:
Excellent use of vertical space for spice organization
Looks polished and professional in any cabinet
Tons of labels and customization options
❌ Cons:
Drawer slide direction is fixed — not reversible
Screw quality is mediocre
Installation requires precision (and patience)
Overall:
This is a well-designed and space-saving spice rack that delivers on organization and aesthetic. If you're mindful of the fixed drawer direction and take your time during install, it's a great buy for transforming messy cabinets into a neat, labeled setup.
