Question: do these come with the hardware shown to attach to a door
Document: Well built and great pressure rating. I replaced the worn out springs and now the cabinet door in the coach opens with ease and stays open ! !
I used these gas springs to keep the door on my aquarium hood up when I was feeding or cleaning. Powerful enough to hold the door up but not too much resistance when putting it down.
They are also surprisingly strong for their size.I was never able to confirm whether or not these actually come with the ball stud mounts, so you might want to confirm this with the seller before ordering. If they don't include them then I would be curious as to why they are in the photo.
returned this product.....have no idea what whomever make these thought they would support......very weak to say the least. Oh well..... still looking for a product that will hold up my old truck tool box lid.
had it for a while now and I'm very happy with it .it works fine, not very difficult to install and smooth
great product, received quickly. directions were complete and the kit was complete. I ordered the wrong size which is not a reflection on the product or company. I can use for another project
great product but i'd envisioned it to be a bit bigger. the description did not give me the lenght of product. anyways great product for its size.
german quility,works good,good packing,smooth transaction.thanks. very good,it;s possibility that i will order more of this products in future.thanks again. and
This product is very good for the seat bench that I used it on. It works great and looks nice. The biggest problem is the poor instructions that have poor pictures to set it up. Actual pictures would be more helpful then the poor drawings.
These Gas springs worked perfectly on my heavy, overhead wood doors.They allow full control and are a breeze to open and close. I was hesitant because such a strong spring might require too much force to close but that was not the case. Since my doors are large and heavy I installed two per and they are still easy to open and close. I highly recommend these gas springs, they are really great.
Answer: no
