[Unused/Opened] All-Stainless Steel Door Chain Security Chain Lock Thank you for viewing. I mistakenly purchased a product for wooden door frames, so I was unable to install it on my aluminum door and gave up on using it. I opened the package, but I haven't actually used it. ■ Product Contents ・ Door chain body set ・ Mounting screws ・ Instruction manual and package backing card ■ Condition ・ Double-sided tape for temporary fixing was attached to the back of the receiving part, but after attaching it to the wall, it was found to be unusable, so the tape has been removed. The tape residue has also been scraped off. ・ Since it's for temporary fixing, you can use regular double-sided tape as a substitute. ■ Specifications ・ Material: Stainless steel (SUS304) ・ Finish: Honing ・ Compatible doors: For wooden door frames ・ Weight capacity: Approximately 150kg (tensile test reference value) ・ Included screws: 3.5 x 25mm ※ This product is suitable for outdoor doors and outward-opening wooden doors. ※ Please note that it may not be possible to install on aluminum or metal door frames.
