Top Shelf TSB-2438 Universal Heavy Duty Window Air Conditioner AC Support Bracket -Holds Up to 200 lbs., No Drilling or Tools Required, White

First, this went together very, very easily. I had it assembled, adjusted, and in the window in a few minutes. Sliding the A/C unit in place was very easy. But a couple thoughts on making it a bit better 1) The alternating pins are very clever, but need to be called out in the instructions. I thought something was wrong for a moment, until I realized how it was walking into place, moving one detent at a time. 2) its not clear in the instructions how the wings that hold the inside of the window frame are supposed to fit up against the window frame and trim. I ended up extending the wings as far as I could within the window (based on the flat portion on the bottom), and let the tabs reach as far as they could. 3) I padded the support against the window with some foam, and put some of the foam that came with my A/C unit (meant to be applied to the window sill) to the shelf in a few contact points to reduce the amount of metal-to-metal contact and vibration (its noticeably quieter, now).

We have ruined our window trim with installing and reinstalling our air conditioner in the spring/fall. I was done, so I started looking for something that was simple and easy and would provide the support we needed. I chose this product because it came fully assembled except four pieces which you need to adjust to your window. It took us a couple of tries to get it installed (no more than 30 minutes) once it is was installed, we slide the AC unit onto the bracket - what a great device. It leveled properly. We liked it so much we purchased 2 more brackets for our other AC units. Highly recommend.

VERY easy to set up, but you do need to poke your head out of the window to make sure the feet are flat on the wall. If you dont do that, and something jostles the air conditioner, I can imagine dire things happening. The instruction booklet, like ALL instruction booklets, could use some work. Maybe larger, clearer illustrations. But, its true, you dont need any tools. One last thing - you need to use alternate methods to fill the gaps created using this bracket. There will be areas in front of and underneath the bracket to fill. Not a problem - I used bubble wrap. Bottom line - I feel that the entire unit is safer, and therefore, we are safer using it.

This bracket is dead-simple to set up and get in the window. However, Ive had quality issues with both units that I ordered. The first unit arrived with part of the main piece bent, which prevented one of the legs being inserted. The replacements right wing, which is one of the pieces that braces against the window frame, has a lock pin which doesnt seem to fit securely into the holes in the wing. The motion described in the manual to adjust the wing causes the lock pin to fall out. The left wing does not have this issue. Im not sure to what degree this affects the sturdiness of the bracket, but Im a little afraid to put an air conditioner on top of it.

Fit great, supports our large ac. We did install a block of wood between the frame and the window, and did end up drilling two small holes for the wings but I didnt mind - worth it for the peace of mind.

I now have four of these brackets. They are very useful for installing any window air conditioner. Even the smallest A/C units weigh 30-40 lbs and that is a lot of weight to be moving around in awkward ways. I first bought one for my daughter after she dropped her A/C out her back window. It is important to visit the Top Shelf website to see if the unit is compatible with your window and wall thickness before purchasing. You dont need to use any fasteners with it but there are two holes that can be used to screw it to the window frame and I have used a couple of screws to attach mine. Although the price seemed a bit high to me at first, after seeing how inferior some lower cost units were in comparison, I think they are a good value.

Youll likely need a ton of insulating foam to seal up all the cracks this leaves, but it solves a niche issue and for that I am very thankful. The rubber feet pads are terrifyingly hard to press in and fall out almost immediately - also the spring loaded button stops for the arms are not particularly made the best - one refused to pop out no matter what I tried. Rest of the item seems very sturdily built. Like some other reviewers I have outside flush vinyl windows and no real good way to brace a heavier AC. The last AC I put in damaged the window due to its weight so I needed something to help with the bracing, but didnt want to fabricate my own wooden bracket or shove a 2x4 in my lawn. I set this flush with my inside frame, so the arms in front grab on the sides of the window sill - then used a ton of foam to seal up all the cracks. Not the prettiest but definitely is getting the job done so far.

This is probably the most attractive window A/C mount, but the position of the bottom rail forced the unit to sit under the window instead of in front of it. This meant that the A/C units top rail didnt have anything to grab onto without additional parts. To keep the A/C unit stable, I had to cut down a piece of wood to wedge into the window track so there would be something for the A/Cs top rail to grab. After painting the wood to match the window, it all looks perfectly fine... but I wasnt expecting the extra work. Ideally, a universal mount would provide all of the hardware necessary to make install relatively makeshift-free in a large number of windows. I slightly prefer the Jeacent mount thats sold for roughly the same cost, although that mount also required me to use a wood shim to get the A/Cs extension panels to sit flush around the window frame.

This is a great bracket that doesnt require any drilling whatsoever, which was one of the biggest priorities for me when searching brackets online. I live in a rental and wanted to avoid doing any permanent damage to the window sills from drilling holes. Also, Ive been able to move the bracket around to different windows with the greatest of ease when figuring out the proper spot for the AC. Other pluses of this bracket: Easy to take out during the winter Enough adjustments to get the right width and angle of the AC unit Plenty of support for my 12,000 BTU unit Really easy to assemble Peace of mind when installing a heavy unit alone Few notes: My AC unit wasnt as flush and snug in the window as it usually is without a bracket, but I feel like this is usually the case with most brackets. I highly recommend buying some AC insulation foam to place behind the panels and to stuff underneath the bracket in order to fill in any gaps. Also, it may take a few tries to get the right angle. My AC is not totally flat underneath so I had to readjust a couple of times to get it right.

I purchased two of these units for window mounted air conditioners. Assembly was simple and each fit the window opening fairly well. Due to the difference in window frames, perfect adjustment was a bit off but nothing that would cause me to not recommend the product. As we are in the Northwest, we only need air about 3 months a year so being able to remove the units and mounts during Winter is really important. These are great products that secure the window air conditioner without any need to drill holes in your house.
