A: This door closer is best suited for interior doors — such as home rooms, office suites, and hotel doors — with a weight of 20–40 kg and a width of up to 1000 mm. For exterior doors exposed to heavy weather or very high traffic, a heavy-duty commercial-grade closer may be more appropriate.

Q: How do I adjust the closing speed after installation?

A: Simply use the included inner hex wrench. Insert it into the adjustment hole on the closer body: press down to loosen the tension for a faster close, or turn right to left to increase tension for a slower, more controlled close. No special tools or expertise required.

Q: Will this door closer rust or tarnish over time?

A: No. The KAK door closer is constructed from solid stainless steel, making it rust-proof, fade-resistant, and water-resistant. It maintains its appearance and functionality even in areas with higher humidity, such as bathrooms or kitchens.

Q: Does the door closer make noise during operation?

A: The smooth roller mechanism is specifically engineered to operate quietly. Under normal installation and use, it produces virtually no noise — making it ideal for bedrooms, offices, and hotel rooms where quiet operation is essential.
