Do not buy this. I have bought 2 Francisco runs and put them together myself with little trouble. This one does not have holes in the METAL pipes to attach the screws through. There is an odd ending to the screw they want you to use that makes it clear they expect you to drill through metal with this tiny screw. There is a barcode that says it will take you to an instruction video but there are no instruction videos for this item. Says the company is thanaddo but the item I ordered was supposed to be from tucker Murphy pet. I have no idea if this is the company’s fault or wayfair. But please order Francisco not this one. Or any other one I don’t care. I got the entire frame together before I got to this part. The instruction manual is terrible so there was no way to anticipate. So now I have to tear it apart and figure out how to box up to return. It’s a huge headache.
