Parts for drying futon X-shaped extendable futon dryer L-shaped parts: 4 Foot caps: 4 For 29.4mm pipes. For extendable types, the thinner pipe may be around 26.4mm, but it should be possible to accommodate this by tightening the screws. If the screws are too short, please purchase longer ones at a home improvement store. Please note that these parts may not fit all pipes. Some may be fixed with eyelets instead of screws. Have they deteriorated and cracked due to the sun's ultraviolet rays? The drying rack pipes are fine, and disposing of them is difficult because they are non-flammable, and bending them is also difficult. You might even have to pay disposal fees. In my case, I didn't use screws, but I crushed the eyelets on the eyelet-fixed type. The screw size fit the holes perfectly, so I was able to fix it well. I couldn't secure the thinner pipe with screws, but it fit the holes, so I could fix it with screws. Even if you replace the futon dryer, it can cost over 5,000 yen. The screws have handles, so installation is easy. Due to work circumstances, the shipping time may exceed 4-7 days, so please be aware of this. Shipping will be via Yu-Packet Plus with simple packaging.
