Description

Product Description A set of grow tent accessory bars designed to provide greater support for equipment while maximizing interior space. Constructed with highly resilient steel to form multiple support systems, the CFM bars can be arranged to handle grow accessories without strain or wall bowing. The durable support clamps double the potential weight capacity for reinforced strength to hold additional or heavier products. Firmly secure the mounting bars in place with adhesive grip padding and hook-and-loop straps for effortless placement and height adjustment. Applications These mounting bars are fitted for grow tent frames of any size to support such accessories as clip-on fans, trellis nets, and drying racks. They can support additional or larger equipment when using the included support clamps. Supplementary lights can magnetically mount onto these bars and be arranged as inter-canopy side lighting.

    • Excellent Addition for Any Grow Tent!
Size: 2x2 Color: Gray
I needed an extra support pole/hanging bar for my tent to hang an inline fan and filter. These bars did the job perfectly. One of the standout features is the versatility of these bars. You can easily change the support orientation, allowing you to run two poles down the middle of the tent. The quality of the steel is top-notch, ensuring that the bars are sturdy and reliable. Installation was a breeze, and they fit seamlessly with my existing 2x2 indoor grow tent. I highly recommend the AC Infinity Grow Tent Mounting Bars if you want a reliable and versatile solution to enhance your grow tent setup. They are worth every penny and have significantly improved the functionality of my grow tent. ... show more

    • Sturdy bars with multiple mounting options
Size: 4x4 Color: Gray
The bars are the same quality as the original tent bars. Installation was straight forward, even with the tent full of plants. I did not take off the tent from their original bars as the instructions stated, and installation was still quite easy. There is extra mounting hardware to accommodate different configurations. I'm using the bars to install a trellis net over my plants, and the bars make placement of the net extremely easy. ... show more

    • Heavy duty, semi permanent style structure
Size: 4x4 Color: Gray
These are great. The quality is on par with AC's expected high quality. These are not for moving and adjusting. These are for setting and not moving them again. Yes, they are a pain to install, but they are very secure, and I don't even use the lower clamps! If you want something you can move every couple days, I would not recommend these. To everyone else, say goodbye to negative pressure eating valuable real estate! These are very high quality poles, with all the AC bells and whistles. I highly recommend. ... show more

AC Infinity Heavy-Duty Grow Tent Mounting Bars 4x4', High Airflow CFM Kit Prevents Walls from Sucking in, Trellis and Supplemental Lights Mounting for All 4x4 Indoor Grow Tents. Works great they’re excellent for keeping the sides of the tent from pulling in and touching your plants extremely easy to install only takes one person and about 15 minutes. I highly recommend this product. I am extremely satisfied with the results. The price was a little steep, but it’s worth it. Does not get in the way of the zippers, however it does make it difficult at the doorway. ... show more

It's a good product and I use it to put my net on it for my cannabis. It's very well built and put together well. I can see it lasting a very long time. I would definitely buy again

    • They do what they’re supposed to do.
Size: 2x2 Color: Gray
Title says it all. Was looking for more structural support for the tent because of the ventilation fan’s efficacy. These prevent tent implosion when the ventilator spins up. I can’t understand the reviews saying they’re hard to install. I didn’t disassemble my tent as per the instructions and still had it done in about as much time as it took me to type out this review. No comment on load bearing capacity because that wasn’t my intention for the bars. Arguably pricy for what they are but you get what you pay for. ... show more

What an actual piece of junk. Anyone saying this product is good or is easy to install, is either affiliated with ac infinity or has no experience whatsoever. I have been growing for quite some time and have a few different brands of high CFM kits. Does ac infinity work with an grower before production? How could you get something so simple so wrong? Allow me to tell you. The installation is a nightmare. First, in their own instructions they want you to remove the walls of your grow tent before installing. I am not a total idiot so I passed this step and just put it on with the walls up. Next you have to hold 2 separate bars and wrap a flimsy piece of Velcro around the support bars and the tent corner bars. Hope you have 3 hands. Next you need to screw on a bracket that supports the support bars.... This is the final product being sold. WHAT WERE THEY THINKING?! This looks like a prototype at best. Big problems with this. They know the Velcro is going to wear out and fail over time so they give a few extra. Maybe come up with a more permanent solution (like grow buds did, I will get to it). Next, metal seems like a good sturdy idea, until you've been growing for a few years and realize metal in a high humidity environment is a bad idea. It does not support any extra weight, stating in the instructions it maxes out at TWO POUNDS of weight or FOUR POUNDS with the brackets under. My plastic grow buds one holds just as much if not more weight. It will rust over time, including the brackets and screws, not my plastic one though. Next, every time you need to raise or lower it's an entire process. I will include photos of my grow buds high CFM kit, what a breeze to install and adjust, takes seconds to do either. A plastic piece that snaps on the corner firm enough to hold, loose enough to adjust height. How hard was that? All we need this kit to do is 2 things: keep the tent walls from bowing and hold a trellis net. That's it. Idk what vivosun uses for their pole connectors, but it can't be a worse idea than this. If I had to recommend a high CFM kit it would be grow buds for sure. ... show more

    • Nice
Size: 2x4 Color: Gray
Definitely sturdy and fit the AC Infinity tent perfectly and comes with spacers to aid installation in tents not as robust as the ACI tents. The poles are robust but only rated for 2 lbs unless you use the provided support clamps which double the rating to 4 lbs. It’s a little fiddly to install unless you completely unzip/remove tent covering but not horrible if you don’t. Install by first applying included self-stick friction/spacer pads on each end of the support tube (2 thicknesses provided) then wrapping the robust, rubber coated Velcro straps around the tent pole and through the loop in the tubes provided in this kit. I’d much prefer a clamp type installation but would likely double the price and these work fine the way they are. ... show more
