Thank you for viewing! This is a holder with a slide adjustment function specifically for SwitchBot, sold on Amazon. Installation is possible with the following steps: ① Loosen the two screws and insert. ② Attach the SwitchBot to the holder. It can be installed by anyone with a screwdriver without double-sided tape, so it's suitable for rentals. (Double-sided tape is required for the pulling operation side of the Switch.) - Type: SwitchBot Holder - Function: Slide adjustment function - Color: White
