AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with X-Digital TechnologyAEMs X Series Wideband UEGO Air Fuel Ratio Sensor Controller Gauges are built upon unique, patent pending X Digital technology that makes them the fastest responding wideband air fuel ratio controllers in independent testing against 17 other wideband UEGO air fuel controllers*.

AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers*. The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter, and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM Wideband Gauge’s center display. This creates the perception of a larger overall gauge, but in a common 52mm size for easy mounting. Its slim depth (less than one inch overall) and ultra slim cup depth of .200-inches dramatically increases its application base and potential mounting locations. The X-Series Wideband UEGO AFR Gauge has a user configurable display via buttons on the gauge face that allow you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-faced faceplate for air/fuel and Lambda are included, and an optional silver bezel with white dual-faced air/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauge’s durability. Black bezel and faceplate included. Please email us after ordering if you would like the white bezel and faceplate

Great for bookshelves!
Size: 9.25 INCH
Heavy duty and super sturdy. The brackets feel solid and well made, and once installed they hold shelves very securely. Great quality and exactly what I was looking for for an industrial-style shelf setup.

Great feel and quality, will buy again
Size: 5.5 INCH
These are gorgeous! The thick, heavy look and feel that I was hoping for, great screws to match (we used different anchors, since the provided anchors are not the strongest style). Similar ones at the local big-name hardware store are at least three times the price and are no better quality. I would (and will) definitely buy these again for more projects. Originally bought the six of these even though I only needed two because the price was still the best I could find, and ended up using all six almost immediately. They look so good, I found more projects for them!

Nice looking. A bit too much flexibility. Did the job.
Size: 11.25 INCH, Size: 11.25 INCH
We made use of these shelving brackets in our kitchen remodel. They turned out great. We used 2x12 Douglas Fur boards that were sanded and painted to show contrast with the brackets. The brackets installed easy enough with a level, tape measure, pencil, and a drill for pilot holes. Other reviewers are correct: the mounting screws that come with it are essentially junk. I had read this and ordered black wood screws ahead of time with the hopes of returning them. I used the 1" screws to secure the shelving to the brackets. The 2-1/2" screws get to go back as we were able to use the included screws to secure the brackets to the wall. But, two of the first three heads on the 1" screws popped off... so, we quickly moved away from those included. There is a little more flex in the brackets than I had expected... they're just a little too thin for 11-1/2" shelves. It won't affect anything for us as we'll just be placing dry food and canned goods on them in our pantry. But, if I were using them for the garage or the shop I'd probably buy a different brand OR decrease the space between brackets. I spaced mine out 12" from each edge and then 12" on center. Works well for our pantry.

Real good quality. Better price then Menards. Missing screws.
Size: 5.5 INCH
Real good quality, very sturdy, and it came with screws and drywall anchors. I would recommend. Only thing is it came with twice the drywall anchors that I needed and missing 2 screws. Not a big deal for me, but someone without screws laying around would have to buy a whole box for 2 screws. Other then that, it’s a good product and would buy again.
