The door stopper can firmly fix the opened door, avoiding the door handle from hitting the wall, skirting board or nearby furniture, effectively reducing scratches, dents and paint peeling, and extending the service life. When carrying items or pushing or pulling heavy objects with both hands, the door is firmly held and will not automatically close. Automatic mechanical doorstops: press once to lock, press again to release. Magnetic doorstops adhere to various surfaces, such as wood, metal, composite materials, and brick walls. Practical and aesthetically pleasing, they complement various décor styles. Made of durable zinc alloy, they are reliable and long-lasting. Equipped with screws and 3M adhesive, offering two installation options: screw mounting or adhesive bonding (screw mounting is recommended). Strong magnetic doorstops prevent doors from being blown shut by the wind, avoid sudden slamming, and keep the door open to prevent it from hitting walls. Suitable for bedrooms, bathrooms, offices, and other locations. However, not recommended for heavy-duty doors. Floor-mounted design; the doorstop rod length is adjustable to accommodate door gaps from 5mm to 30mm., Manufacturer: WLH Alexanders
