Review on SLIIMU Anti Slip Adjustable Stabilizer Accessories by Solomon Inks

I have a 16 foot (two 8 foot sections) Werner brand aluminum extension ladder at home. My house is on a slope, so it can sometimes be difficult to climb stairs and find enough logs to support a leg. I've been looking for stair levelers for a long time, but the cost always seemed too high. Now I find them at a very good price and once installed they work great. But how do you get there? On my ladder, the leveling frame attached to it is too long from the bottom of the ladder upright to the first rung (which is essentially riveted to the uprights). This meant I had to set the frame over the first rung, which limits the overall leveling ability to about 5 inches. See photos. Simply measure from the end of the ladder to the first rung. If this distance is less than 5-1/2" the length of the interlocking frame, you will need to fit the frame over the first rung like I did. (Note: you will need to remove the factory feet.) You will need to drill four holes in each vertical. I used a 1/4" bit and it fits perfectly with the supplied M10 (6mm) screws (and matches the screw hole in the frame). I pressed the frame against an edge of the upright ladder, drilled a hole through the bolt hole, attached the bolt/nut, then drilled the next one opposite, attached that bolt/nut, then drilled the last two holes. This ensured everything was level and a perfect fit. The bolts are over two inches long, much longer than necessary, and can pose a trapping hazard. I ended up replacing them with 3/4" bolts. I used the included nylock nuts to keep those bolts from loosening. I then attached the rubber feet, which was the next problem. The legs have a threaded rod made of steel, which screws into the underside of the legs. Above the threads, the shank is flattened to accommodate the wrench for tightening. However, the two flat areas are not parallel, so the key gap is slightly wider than 17mm on one side, while on the other side it is only 15mm. It was one of the legs. The other foot was closer to parallel. As for the safety product, this obviously poor workmanship worries me. After the legs were attached, I went outside and tested the new levels on the wall of my house they worked great they were easy to adjust and held where I set them BEFORE PARTS - Strong after assembly. - After some work they fit on my 8ft Werner aluminum ladder. - Wide legs seem to be very good. My ladder is at a logical attachment point. The compromise mount limits the leveling height. Poor workmanship in the key area for the "leg" shaft. The bolts come out way longer than necessary, at least on my ladder. I've never seen a ladder so long that you need bolts that long. However, it is recommended to prepare for a trip to the hardware store to have the screws replaced and spend about half an hour installing them on your stairs.
