☆ Bulk purchases welcome! Please check profile for details. [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 I found it unusable after sticking it to the wall once, so I removed the tape. 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.
