Question: Are these plastic or metal? I want to be able to leave them outside for an extended period of time and everything rusts here. Thanks.
Document: i have used the horses often and found them to be satisfactory. i hav'nt put much weight on them to atest to that but found them very sturdy...i like the feature of being able to adjust them to different heigths... you want to be careful the first time opening the horses as i pinched my finger but only took one time doing that before i found a proper way of opening them up..you use the bottom tray to extend them open and closing them.
They came damaged on the bottom of one of the legs, but I was able to sufficiently repair. However, when I extended the &#34;arms&#34; on the set and put 25 pounds of 2x6s stacked on them, the extendable &#34;arms&#34; folded. I'll keep them b/c they're decent sawhorses without the extension, but I'll stick to my wooden sawhorses for anything over 300 pounds.
I'm using these sawhorses as supports while I saw boards for my deck. My chop saw is set up on my Workmate bench. The adjustable height on the horses is really nice. I set them once 4 weeks ago and leave them there. The only issue, and minor, is that they have rubberish stops on the face that hold the board. For my use, I want the boards to slide across the sawhorses, not grab and restrict.I pulled the stops off the sawhorses and am much more happy.
Have been wanting these for some time and got them for a good price. Have not seen anything wrong with them. Had a set of horses I made from 2 X 4 that lasted for years and I expect these to last just as long. Also like the ability to adjust the working height of the new horses. Received them in good condition.
Do NOT buy this product! The adjustable sawhorses are overpriced and poorly designed. When my first set arrived, the middle panel that stabilizes the sawhorses was detached. I tried to snap it into place, but it required so much force that I was afraid I would damage the product. I called Stanley and they recommended that I return the product. I did so, and when the second set arrived, the middle stabilizing panels were also detached on one side. This time, I tried to attach the stabilizing panels.
They are sturdy enough so far. I did crack the plastic on one of them by clamping too hard, however, I at least partly blame myself as I was using the wrong end of some cheaper clamps. Got these at the "depot" for 60 bux regular price doe, so $75 on sale on amazon isn't so hot.
My father had a set of these and a set of cheap saw horses and let me tell you it makes a huge difference. I've gotten into making cornhole boards and his other set was just too flimsy and not wide enough to hold them. I went out and bought a set and now everything just runs a little smoother. I will say tho that if you're gonna buy them, do yourself a favor and go to Lowe's because they are about $60 there.
We got these because we don't have a lot of storage space and our older backs won't tolerate extended bending over as we work on projects. These store easily and are great for our lighter projects. Not sure they would work for a daily user, but are perfect for us weekend warriors.
just what I wanted, thank you
I very much like the adjustability feature of these horses. Am getting a little older and now I don't have to bend over to work. Very stable.
Answer: yes
